I’ve got something going on that is confusing the hell out of me. It might be something stupid that I haven’t thought of, but I really don’t know.
1987 2.5l TBI 4sp, between work and whatever else, it’s been dead about 4 months now. Started initially then died after about 30 seconds. Then stayed as a crank no start. After my basic tests, I’ve got fuel and spark, and my timing is good. I don’t know why I suspected something with fuel, but if I unplug the fuel relay and pour a small amount of gas into the throttle body it’ll run for a few seconds perfectly fine.
Fast forward to now, I noticed if cranked too long gas starts free pouring out of the exhaust and spark plugs get all fouled up. After that, when the plugs are cleaned up, I can disconnect the fuel lines completely and it’ll run for several minutes, until wherever it’s getting the fuel from runs out. I did a fuel pressure test on crank and get about 13-16 psi. I have changed a few things but kind of wanted to start at a baseline. I desperately need help, because I cannot figure it out. Anything would be appreciated immensely.
