Engine Performance problem
1993 Jeep Cherokee 6 cyl Four Wheel Drive Automatic 200000 miles
ok my inline 6 want to crap it starts fine. But as soon as it starts it dies runs for 2 seconds then dies or Idles really rough then dies. Best I can figure it does so untell it uses up the fuel pressure. So far I have changed:
idle air control valve
trottle position sensor
fuel pressure regulator
coolent temp sensor
so far im up to 500 in parts.
I hooked up a pressure guage to the fuel line and before parts it was about 31psi before start then would drop to 15 after start and then just kept falling tell it died. Now that I changed the fuel pump its worse.
the only differance the fuel pump made is now my fuel guage doesn't work.
I have no idea where to go next. Any ideas? Would like it running by work in 2 days.
have the same problem?
