Engine starts up just fine when cold. Let it warm up and shut it down, the starter is so slow it won't start the truck. Let it cool for 5 to 10 minutes and it starts up fine. No matter how long it runs for, after warming up the starter doesn't have the power to rotate the engine fast enough to...
Ron, I have learned so much on this site from your posts. Thanks a lot for helping me, and all the others you have helped that in the end, wound up helping me lol.
It was me. I was the problem. When I did the engine swap, I forgot about the trans to intake vacuum line. It shifts like new now! I really need someone to come take all my tools before I do something REALLY stupid lol.
I dont have a tach, but I'm certain my 87 2.9 4x4 auto isn't supposed to ride 1st gear all the way to 44mph then shift into 2nd and ride that to 60 before hitting 3rd. And idk if there is an overdrive, if so, it don't work. Had it up to 75 and of never kicked in.
I did not see a fuse spot for it in the under dash box. I don't have a fuse location under the hood. I did however notice my break lights don't work and with the requirements of the breaks to be on for the 4x4 to kick on, I'm hoping a new break light switch will fix two problems.
I have zero experience with these. No clue how they work. I just know this one doesn't. In park, in neutrual, engine on, engine off, either button held for 10 seconds nothing happens. Where do I start my trouble shooting?
Whelp the fuel pump quit again. Following these instructions from this page ( THANKS RON!!! ) I found a bad relay, brown base.

Fuel pump relay's coil gets 12volts with key on, but has no Ground so relay doesn't close
That 12volts comes from EEC relay(brown base)...
I just replaced the IAC and that made no difference. I DID notice if I allow the pump to prime 20 times before cranking that it will start, run for 2 seconds then shut off immediately.
With that in mind I'd assume my previous thoughts were wrong. I'll rediagnose my fuel system, starting with...
I've tried to pull codes. Even though I have a spot on the dash that says "Check Engine" it doesn't illuminate. My multimeter is digital so I need to buy a test light.
