Re: Columbus..the 1957 IH 4x4..
Noid lights showed up in the mail today... Injectors not firing ...no time to troubleshoot for a few days

Re: Columbus..the 1957 IH 4x4..
Good luck, I don't know enough about diagnosing the modern stuff.

Re: Columbus..the 1957 IH 4x4..
Thanks Dale..

Re: Columbus..the 1957 IH 4x4..
Got with my tuner guy today.. he looked thru his files where he did the ecm unlock.. he said it should be good.. and to double make sure, he hooked up and checked the ecm itself to make sure everything was there..it was .. he already had his suspicions as to what it might be.. crank sensor not reading.
He says you get the initial injector pulse, then the ecm needs to see engine rpm to continue firing the injectors...that's why I see the 1 time injector fire when cranking... since this was a running engine when I did the swap, he said I need to check the crank sensor wiring.. he said hes seen 3or4 harnesses that were pinned wrong in the past yr or so..and just to rule out the ecm ,were gonna put it in another truck tomorrow and make sure it runs.. ..Still not sure how to check the crank sensor..but he did say if I had a hand tuner I could check the crank sensor signal with it...gonna check wiring 1st..

Re: Columbus..the 1957 IH 4x4..
Thanks Regan and Dale...it seems nothing's simple ..
I've ran all the wiring..checked pin locations, and continuity from plug to plug on cam and crank sensors..everthing checks ok.. guess my next step will be replacing sensors..

Re: Columbus..the 1957 IH 4x4..
Good luck Greg. I bet the crank sensor will fix it. And if it doesn’t, don’t forget a new part isn’t necessarily good.

Re: Columbus..the 1957 IH 4x4..
Long overdue updates...
I'm still fighting the no-crank issues.. I've done everything I know to do.. Checked all grounds...all good..doubled them up anyway Have constant 12v and key on and crank 12v Checked fuel pressure..58psi Checked crank sensor, it bench tests good and backpinned at the ecm plug it shows signal Checked cam sensor, it also bench tests good and backpinned at the ecm plug it shows signal Had 37 (haha) people telling me to change them anyway..so I did..still no crank.. Checked wire pin locations in plugs, all good Had ecm checked twice..no issues there.. put it in 2 diff trucks..both ran fine with my ecm.. Checked injectors multiple times ..all spray good.. checked injector solenoid with stethoscope, can hear them firing.. remove intake , raise up above engine ..crank it over..all 8 injectors are spraying.. Pull engine down to check cam , marks line up perfect.. still will not crank.. Pour gas in throttle..itll crank right up every time and run til poured in gas runs out.. Trying to get up with a different tuner and see if he can figure out what's going on.. Very very frustrating..so far 2 different tuners, psi tech, and 3 different mechanics all say theres no reason it wont run.. So til that happens ,on to other things...

Just one random thought. When engine is cranking over, does fuel pressure stay at 58 psi? Since the engine runs with gas poured into it, it should run with injector sprayed gas. If it isn’t, then I am theorizing something is happening with the actual fuel supply through the injectors during crank. With a carburetor, we checked fuel pressure and volume. If a gas supply line is pinched off going to your injectors, it could display 58 psi static and drop off rapidly in crank as the injectors are firing. Or pump could be cutting off somewhat during crank. |

Re: Columbus..the 1957 IH 4x4..
When I did the exhaust, I didnt like how much side sway the pipes had,,
So i got some 3 hole mounts.. Fabbed up new support bracket.. Works great.. 3 hole mount vs the 2 hole mounts I was using

Re: Columbus..the 1957 IH 4x4..
Also moved the truck over to my temp paint booth..
Gonna have to touch up a few spots with epoxy primer.. Then the cab painting will happen.. Things have finally slowed down at work where I hopefully will have more free time for truck stuff

Re: Columbus..the 1957 IH 4x4..
Doug, the way i have the gauge mounted I cant see it while I'm cranking.. but I have looked with key on shows 58psi, after cranking it still shows 58psi.. I'll need some help to monitor it while cranking..
But the injectors are spraying while I'm cranking it .. Richard..I know what you mean.. I dont have a problem with electronics..when they work..... but when they dont , I get aggravated, real quickly.. I've done several of these..but this is the 1st time I've had all these issues

Re: Columbus..the 1957 IH 4x4..
Me to Dale..!!!.. I'm gonna do the paint 1st though..
So after getting a chance to do some sanding, I found a couple of spots on the back of the cab I just wasnt happy with.. these spots are where the inside cab brace is welded in.. it gave a high/low spot on the outer cab skin.. so I did some hammer dolley work on it and skimmed it with filler.. the drivers side was way worse than pass side.. Then after going over the cab ,I decided to just respray the whole cab with epoxy.. and high build.. So got it all resanded with 80g and started taping everything up today.. Hopefully paint coming soon This is the 2 spots I worked on .. I couldnt get it "perfect " but hopefully itll be ok

Re: Columbus..the 1957 IH 4x4..
Well after several delays (of course) , I finally got all the sanding done,
Inventoried my primers and found that my 2k high build was bad.. probably didnt have enough to do several coats anyway, got plenty of epoxy.. so I'll hold off til next week, and grab some more high build .. I'm gonna do the epoxy, and follow that right up with high build inside the primer working window... hopefully eliminating one round of sanding So I've spent some spare time taping it up.. Hey!! Looky here...truck in a bag..!!!

Re: Columbus..the 1957 IH 4x4..
It's progress. You'll get it done. Almost on the downhill side of things now.

Re: Columbus..the 1957 IH 4x4..
"Truck in a bag". That was a clever attempt to cover up the disappointment of not being able to prime like you planned. Pun intended.

Re: Columbus..the 1957 IH 4x4..
Primer day.....
Sorta...Well....... I reckon if theres a way to screw something up, I can find it.. Got up this morn... Mixed up my epoxy.. Laid down 3 coats...waited 40-45 min between coats... All good..epoxy layed down nice.. Plan is to come right over the top of the epoxy with the high build.. Spec sheet says 30min to 3 days window for topcoat.. Waited a full hour.. Layed down 1st coat..all good.. Waited another hr, sprayed second coat.. Went all the way around the cab ,all was going good til I got back to my starting point.. WHAT THE HECK!!!!!!!!!!!!! when I got back around the truck to my starting point I noticed this fancy paisley pattern in the primer.. Right before my eyes I watched the whole truck cab turn this pattern.. I'm bummed... dang it !!!!

Re: Columbus..the 1957 IH 4x4..
Wow! That is all I can say. You have some real talent. I don't think anyone else could make that pattern if they wanted to do so.
Sorry, but that is a true bummer.

Re: Columbus..the 1957 IH 4x4..
Dammit! That sucks for sure. It almost looks like a chemical reaction. You seem to have the same kind of luck as I do.
