1990 still won't start. Just cranks and cranks
Here is what I have done:
New thermostat
New overflow reservoir
New battery
New cables
New plugs
New wires
New CPS
New distributor
New fuel injectors
New fuel pressure regulator
New fuel pump
New fuel filter
New air filter
New/different (boneyard) throttle body (off running 1987 Waggy)
New/different (see above) IAC, TPS, and MAP sensor
Tested my fuel pressure (the dealership said my pressure wasn't accurate). In 10 tests I read 5 36s, 3 37s, and 2 38s. That tells me that my fuel pressure is a-ok.
The plugs are brand new. The truck has not run since the were put in. I pulled one the other day and it was "sooty," I assume from turning the truck over and over trying to get it to start. There was no oil on the plugs, just carbon.
I know the truck tended to run a little rich in the past. I also have smelled a little fuel out of the oil filler cap on the valve cover.
I have not tested the spark plugs for spark yet, so that will be forth coming, but I can't imagine that is it.
How can I test that it is getting the air that it needs? When I installed the TPS on the throttle body, how do I determine exactly where it needs to be placed? I just put it on, but of course it can be adjusted by loosening the torx and moving it slightly right or left...
I have followed every vacuum line and there is no violations anywhere.
I even put in a brand new headliner...just to appease the Jeep gods...It got me nowhere..
HELP
