Sweet man, so when do you think you will be driving this thing?

In the next week or two in naturally aspirated form. With turbo about 2 to 3 months from now.

Custom throttle cable installed and temporary intake idea thrown in place. I'll shorten up one leg of the 90 degree bend and lengthen the other to move it away from the radiator to clear the fans.

Coming along real well

Cool man! I bet you will be glad to be driving Mr.Green Jeans again..

OK, so technically the engine would run right now, but I can't start it until I fill it up with fluids and put an oil filter on it. I need to form one more transmission line to the radiator... I still need to wire up the fans and mount them as well. I will need to rewire 2 injectors as I must have pulled on them too hard while doing the fuel lines and the wires came right out of the clips...

Fuel lines went in today and pressure tests good at key on position. Finished up the cooling system hose routing for the steam line return to the old radiator heater return spot. He's getting there!!! The next day or two I should have an initial test drive under my belt and be working out any bugs.

[Hankster]

Hell yeah, your close now!

Looking good, keep at it. I know how it feels to be so close to driving it. I just need gas and to get my drive way clear of side jobs, LOL.

Well I went and bought all of the little things to finish it up in the morning, but we went to Furious 7 and then to a car show with the Bad Boyz Mustang Club of Iowa and then I had to mow which pretty much killed off the day. This week looks like rain with bad thunderstorms and possibly tornadoes this afternoon. Hope I get to finish it this week and it doesn't blow away!!!

coming along nicely

First little "pop" of a test fire. Once exhaust and wiring is all tidy, I'll take it for a test drive.

Clicked on the link but the video came up as private and wouldn't play? Tease!

[bnoon]

Trying to fix it.

[bnoon]

Shows as public now...

[68Timber]

Awesome! I lol'd a little over your reaction, but only because I get that way too.

Yeah, it was a true "yay" moment after the Friday night I had at work. Was supposed to be a half hour maintenance window for our server that turned into a 5 1/2 hour mad thrash, that then killed half of the day on Saturday to sleep. Sleep pattern was still a little off last night too.

Tonight I can tune it and remove the VATS that kills the truck after a second or so now (I left it in on purposed in the video, just didn't have time to fire up the laptop yet). And I also need to mount/wire up the fans, and tape up the harness... Then I can maybe test drive it.

[bnoon]

I went to program the truck last night and no fuel pump prime with key on. Verified power to the fuse block and ECU through the PSI harness. Looks like my ECU died. Used/verified one from Ebay seller coming by Saturday. Delays delays...

eff that

that is ****ty news man. computers are a pain sometimes

[bnoon]

No doubt.

Well Friday I got the used PCM from Ebay seller. Plugged it in, worked fine. Pulled the stock config, removed VATS, downstream O2 sensors, and reprogrammed it. Fired right up. Then, as I was topping off the coolant with it running, the dang thing dies and no fire on restart again. Killed another one. Something is wrong with my wiring... I had thought that I had caused it with loose battery and ground cables the first time since I had left everything loose just in case I needed to rip off the wiring really quick for fear of fire or something, but apparently I really did wire something incorrectly. Another used PCM is on its way from the same company and tonight I will be going pin by pin checking for power where there shouldn't be, ground where there shouldn't be, or dead shorts. Ugh.

Yeah, it comes up with stars and punctuation marks on the forums.

I went through pin by pin and found ground where there were supposed to be grounds and power where there was supposed to be power, nothing out of place. The only thing I was seeing that was questionable was about a 1 volt difference from keyed ignition power vs. power direct from the battery through the junction block, so I'm thinking that the 1 volt difference may be back feeding through the PCM somehow and killing it. I'm going to move all other keyed ignition powered items off to their own feed, power the ignition feed to the PCM through a relay to get full battery power, and upgrade the grounds to the frame and body and bring them all to one point to eliminate any voltage differences.

sounds like the "non-running" state is OK. how much running time do you get before the PCM dies? do you have enough time to make the same ground and voltage checks while its running?

[Dieselwrencher]

Wow, the quick start up sounds really healthy! That sucks about the ecm fry-ing issue. It's always some small PITA problem. Good luck with it Brad!

The first one only had a few split second test fires on it for running time, the rest was about 20 minutes total of "key on" time while I was checking the fuel pump for prime pressure/etc. The second PCM had about 8-10 minutes of "key on" time and 8-10 minutes of run time, so similarly a 16-20 minutes total with the keyed power turned on. It's a power issue, not just while running.

Thanks man! The 5.3 with this LS9 cam is very mild compared to the built 350 that used to be in there, but the power brakes will sure thank me for that LOL! The 5.3 with the 4L65E will be quicker too with the steeper first gear I'm thinking, then comes the boost...

[bnoon]

Runs and drives wahoooooo!!! I still have to go bleed the brakes and install the fans and tune tune tune, but it's alive!!! Slow drive through the neighborhood points out the rich condition right now, but to have it MOVE under its own power... So nice!

I put the power feed to the pcm on a relay and separated the other power feeds to the speedometer adapter on a different lead as well as the fuel pump all as I stated before. The second PCM even still works! Now I can burn my final tune to my third PCM and have a true spare. Ahhhhhh I feel so good right now.
