Re: Crusty Rusty Leaky Squeaky 67 Step
That's great Vic i'm glad to hear everything is working out for you.
You will be tearing up the streets again in no time. Don't be too hard on the old girl she is just trying to live up to her name "squeaky" haha Is the belt squeal something as simple as a misalignment? Last edited by Xeen; 06-16-2018 at 10:00 AM. |

Re: Crusty Rusty Leaky Squeaky 67 Step
Very clean work on the bed access panel and fuel system! Bummer about the belt squeak, my buddy chased the exact problem on his 67 Camaro. I don't know what he ended up doing to fix it..
Very informative thread as always. |

Re: Crusty Rusty Leaky Squeaky 67 Step
I have a question on your "dim" check engine light. Where does the signal for this come from? Are you tied into the original check engine light that came with the harness?

The relay box has a separate LED MIL in it that seems to operate correctly and doesn't have the dim glow when the engine is running. Only the redundant light on the dash connected to ignition 12V and the MIL wire displays this behavior. If the circuit works by supplying either a ground or an open, there should be no dim glow. Light would be either on bright or off. However, I ran across a post on one of the forums that said the ECM worked by supplying ground when a fault is detected or 12V when running and no fault present. If that were true, I could see how the light might have the dim glow since the charging system operates at 13.5V+ which would result in a net 1.5V+ difference across the redundant MIL. I don't recall where I saw that post, but offhand it doesn't sound correct. So I've just been ignoring the dim glow. I need to pull the console to fix the starter wire problem, so I may throw the meter on the MIL wire and see for myself what it's doing.

Re: Crusty Rusty Leaky Squeaky 67 Step
On my Ls swap I wired a check engine light and mounted it on gauge cluster bezel. Ecm provides ground when a fault is detected and other wire is 12v ignition feed. Hope that helps people that were curious.

Got the Continental Elite/Gatorback serpentine belt installed today and it's quiet as a church mouse. Don't know how long it will stay that way, but it was great to hear nothing other than exhaust noise. Now I can remove the alternator and send it back to the manufacturer to have the regulator replaced and then dyno tested. Hope to find some time to get the bed back on this weekend. We finally had to put my dad in a skilled care facility. It's a hundred miles from here and we've been back and forth nearly every day getting him set up. The place is in his hometown, so he's been pretty upbeat since moving in. Truck stuff has had to take a backseat, though.

Re: Crusty Rusty Leaky Squeaky 67 Step
The bed is back on, although I'm still doing some adjustments. Found out that with the Accuair in the lowest position, the driveshaft just barely kisses the bottom of the air tank. So if you moved forward, it squealed a little bit. So I spaced the tank up .400" while the bed was off and now the top of the tank just barely touches the underside of the bed. To remedy the situation, I installed the 1/4" thick, square rubber insulators between the frame and the cross sills. I'm still figuring out how snug the fasteners need to be for it all to sit just right. Posted a photo below of the access panel in the bed. Should never have to pull the bed again for fuel tank maintenance.
To all who expressed their opinion that the carbon fiber side mirrors looked out of the place, I say thanks for being honest... and check out the replacements. These are '69 GTO/Chevelle mirrors. My second new car ever was a '69 GTO Judge and I always liked the profile of the side mirrors. The passenger side is at the limit, adjustment wise, but you have a clear view out of it. The driver side view is way better than the ones that were on there. I was able to position them to cover the existing holes, so I sealed them with a dab of silicone and it's good as new.

Re: Crusty Rusty Leaky Squeaky 67 Step
I just got caught up on this, wow it looks great! I like the new mirrors, good call on that. All of the electronic problems you ran in to are disappointing, I expected better out of GM.
Kudos for hanging with it. -Richard

I've been working on the universal bed mat cutting out all the various openings. They're made out of some tough material. Finally figured out a combination of a jig saw, various hole saws and a coarse drum sander works the best. It would have been nice to find one that fits out of the box, but this will have to do.

Re: Crusty Rusty Leaky Squeaky 67 Step
Well, a lot of water under the bridge since I last wrote. I finished up the bed mat and got everything back in place. Looks a lot nicer than seeing the butt ugly access panel. Plus it's much more anti-skid than the spray in liner.
I also repaired the starter circuit wiring and ran a dummy wire for use with an ECU controlled fan relay in the event the PWM fan controller takes a dump. Having the wire there will probably mean I'll never need it, but just in case. ![]() Pulled some much needed maintenance (oil change, fluid checks, etc.) Also removed all the plugs to have a look. They looked pretty crappy, but I figure they're like that due to all the past fuel issues. They should clean up after some highway miles. While all this was going on, I removed the ignition switch and put the fuses back in the Advanced Keys pushbutton start only to find the truck would crank but not start. I put the stock ignition switch back in and it started just fine. Put the fuses to the AKPBS back in and it started with no problems. So I just left the stock switch plugged in and cable tied it up under the dash for the time being. It was finally time for a test drive. Ryan and Rachel (twins from Houston) are visiting, so Ryan and I hit the road. Drove less than a block before deciding something wasn't right. Popping and banging like it did the time I had a vacuum leak. Pulled over and checked but that wasn't the problem so we limped back home. When I originally installed the vacuum referenced regulator, it was set at 60psi out of the box. But when you attach the vacuum hose, it pulls about 5 or 6psi off at idle. According to the documentation that came with the LS3, it needs a vacuum referenced regulator set at 60 psi. So I adjusted the pressure up to that amount at idle and it seems to be running better although not 100%. It still has an intermittent low speed surge and is harder to start than it should be. It will start on the first try as long as you don't even rest your foot on the accelerator pedal. I have a bad habit of driving with two feet and if I come up to a stoplight with my left foot on the brake and the right still resting on the gas pedal, it will want to stall out. So I'm going to have to retrain myself to either use my right foot for everything or move it well away from the gas if I need to stop. I've read that poor idle quality, hard starting, stumbling and etc. are fixable via the tune. However, I'm reluctant to take it back to the guy that did the work on it back before we went on our trip. His communication skills left a lot to be desired. I don't know whether I could take the truck in to my local Chevy dealer who sells the GMPP crate engines and have them return it to the original tune to see if that improves it or not. It's drive-able but it doesn't instill confidence when it displays these little quirks. I have an Innova 3160g code reader / scan tool due to arrive tomorrow. Jason7121 recommended that I connect a scanner and drive around to capture some live data. It should also allow me to see if the ECU toggles between open and closed loop like it's supposed to. I don't know if the permanent emission codes that were set are interfering with the operation or not. Will post more when I know more.

Re: Crusty Rusty Leaky Squeaky 67 Step
Vic - vacuumed referenced regulators should be set with the vacuum line off. Also, within the tune, the fuel pressure should be set the same all the way across instead of a sloped line. Fix theses 2 things and install a new set of plugs and I think you will be pleasantly surprised at how different it runs.

Re: Crusty Rusty Leaky Squeaky 67 Step
First off, nice build thread, very nice work sir. Question, I am working on my floors and rockers and cab corners and they are all loose and I will have to re-align like your doing. My question is how did you pull the rear cab posts forward when they attach to the floor pan with bolts?? Did you make new holes for the bolts in the floor pan? Come along pic reference.
Thanks, Tom Quote:

Re: Crusty Rusty Leaky Squeaky 67 Step
Used CRLS to haul Dad's old recliner to the Salvation Army this morning. Up to its old tricks... popping and banging, not wanting to start on the first try, etc. Seems like there may be a problem with the O2 sensor heaters. Once the engine warms up fully, it settles down and runs a little better, although it still surges at part throttle a little as well as an outright misfire now and then. After it warms up, if you give it full throttle, it cleans out and pulls hard. But then at city speeds it starts to act up again.
I put the new scan tool in Live Data mode and the only numbers that looked really odd were the O2 sensor voltages. Kept banging back and forth between .05V and .9V. The graph looked like a series of spikes. But then again, I don't really know what to look for either. It now has the original two permanent DTC's (P0131 & P0151) and has added two more of the same as well as two more in pending codes for a total of six codes. (The same two codes repeated three times.) I'm going to put it in "record" mode tomorrow and put a few highway miles on the truck if it will cooperate to get a more complete data dump. I have an appointment at LSXkilr on the 25th to see if they can isolate the problem(s) and get it running right. I'm at the end of my rope. I removed the pushbutton start completely and reinstalled the ignition switch in the dash for now. If I ever get this sorted, I'll reinstall it. There's a show in Bonner Springs on the 28th we go to every year. Be nice if CRLS was able to make the trip without puking.

Re: Crusty Rusty Leaky Squeaky 67 Step
I think you should take it back to the guy who tuned it and tell him you want him to reset it back to stock configuration and see how it runs at that point, without a baseline it makes it tough to diagnose potential problems.

If it has a mass air flow sensor make sure arrow on sensor points toward the throttle body I have seen this on backwards several times.

Re: Crusty Rusty Leaky Squeaky 67 Step
Hey Vic, Sorry to see you're still having problems with the LS. I did a quick search on Rock Auto to see if your MAF sensor was available through them. They have the GM part for $50.89, and an AC Delco version for $48.79. There are cheaper alternatives, but if you're looking for true GM, these are available, and they have cheap and fast shipping too.
