Topic: no spark need help

[tom85]

so a few days ago i pulled the old motor out of my 89 pickup which ran and put my new 22re into the truck. now it wont start i narrowed it down to no spark and that's about as far as i got.

Best thing to do, is grab a FSM and go through the wiring with a volt ohm meter.   When I got my 87 22RTE, it wouldn't start.  Turn over, but no fire.  But I didn't get serious into it, since I was gonna replace the motor anyway.  When I ran through the harness with a volt ohm meter, I found the wires going to the coil, had fried, because it ran directly over the exhaust.  So, I had a spare harness, and I spliced a longer section up and around the firewall to the coil.  So, now I have no wires running over the exhaust at all.

yea ill check into it maybe I pinched a wire putting it in

That's a very common mistake.     Just pull the harness from the ECM and push it back into engine bay, and pull the wires from the coil, and find the wires and check for resistance. 

When I put my motor in, first I went from a 22RTE to a 22RE, and I wanted everything perfect.  I had many people tell me to go through the harness.  I'm glad I did.  I must have spent 2 whole days with a volt ohm meter, fsm, and alot of beer.  In the end I was glad I did.

I should have done that with my 85 I had bad y connecters for the fuel injecters. I try to look into it tomorrow if I get a chance

well I took the truck to the dealer to get it running. Turns out i had the distributor in 180 deg. out. they cleaned the throttle body for me to help the idle. and there was a recall on the tie rods so they replaced that for free. Runs like a champ now i just have to finish breaking in the motor then start my lift and sas
