This is killing me
I have a 1994 XLT 2wd 2.3L 108000 miles. It developed this problem, when it's cold it starts but after a couple of seconds it shuts off. Sometimes it starts up and runs and sometimes it does it again. Once it is warm and I shut it, off say when running to the store, I come back out and unless I open the throttle a little it just cranks. Seems to be running a bit rich. What I have done: Replaced CTS, TPS, AIC, EGR Controller, coil packs, plugs & wires. Checked O2 Sensor, fuel pressure KOEO 40 psi, Engine Running 35 psi. Let it set and the pressure drops off about 5 psi in 30 min. The truck runs fine once it's started. I'm wondering if the injectors may be leaking. Any Ideas?
