Crank no start

[preston5.9]

I have a 1991 2.9l 5spd it died when it got warm for a while and now it won’t start at all. so i cleaned grounds replaced tfi module, cleaned IAC, checked for vacuum leaks, and replaced fuel filter. I also ran injector cleaner though it incase it was a dirty injector. It holds 40psi fuel pressure and has spark and compression. I’m not familiar with these motors i’ve read to replace crank sensor i’ve also read they don’t have one. What else should i check? TIA

2.9 no crank sensor. it is tfi with a distributor. assuming you didnt cause an issue with the module replacement.

do the injectors have power?

idk if they have power i will check tomorrow

I tested the injectors and they do have power and pulsate like they should. I’m at a loss i’m thinking maybe replace the distributor?

Did you pull the distributor to change module?

If its sparking it might not be sparking at the right time.

Loosen the distributor and pull the SPOUT connector, see if it starts, if not mark where the distributor position is and twist it around a bit see if it fires...

If it does you need to set your timing....if not...we'll go from there.

Also...what color is your new TFI module?

 

[preston5.9]

OK, I will try that. The tfi module was light gray.

OK, I took out the spout connector. Loosen the boat on the bottom of the distributor and rotate it a few times to see if it would fire. Still nothing happened. I was almost certain it was something in the timing. Could it be an ECm issue? I took off the ECM. The connector had some corrosion in it, and I read that the capacitors could go bad inside the computer on the circuit board. I took some pictures if you think that could be it. If not, what else do you recommend. Thank you so much for the help.

I mean....i guess its possible but your injectors are getting pulse, so the ECM is running that...your fuel pressure is good so its running the pump, and you got spark....

But its worth a look

Okay if not that what else would it be?

Wiring.

But i still think its a timing issue

Sorry to bother you. i dont know anything abt these motors or really any old gas motor im a diesel guy. This is just a truck i run around the farm in so i dont wanna just dump money and parts in it. Is there anything else to do to diagnose it if it’s a timing issue.

Timing is set by the distributor and a timing light flashed on the crank. If you loosened the bolt on the distributor and moved the distributor at all, it is now out of time.

Clean off the crankshaft pulley and find the timing marks. There’s a pointer on the block above the pulley on the passenger side, that’s what you use with the timing light to line things up. Bar the motor over until you have the #1 cylinder (passenger side front) at TDC (Top Dead Center). Pull the distributor cap and adjust the distributor so the rotor is right about where the button for the #1 cylinder spark plug wire sits. I like to leave the hold down bolt just loose enough that I can turn the distributor by hand, but having some resistance so it doesn’t just move on its own. Pull the SPOUT connector after putting the distributor cap back on and hook up your timing light.

Now this is best with two people or a starter switch. Crank it over and if it doesn’t fire, turn the distributor slightly one way and if that doesn’t help m go slightly the other way. You don’t have to turn it very far before getting to another cylinder so it shouldn’t take much. Once it’s running, shine the timing light on the pointer and crank pulley. Offhand I don’t remember exactly what you set it at because it’s been about 20 years since I last did it. Once it’s set right, tighten the distributor bolt and shut it down. Put the SPOUT connector back in and clean up.

Okay thanks a lot. I will get back to you after i get a timing light and figure set the timing.

Initial timing is 10* BTDC...with SPOUT removed.

Dont try to time it with the SPOUT plugged in
