Engine Mechanical problem
1991 Chevy S-10 6 cyl Two Wheel Drive Automatic 227000 miles
Reading through some of the other forums, this is the one that helped me best. 1991 s-10 4.3L will start when cold but will not start hot. Fuel is not injecting into the throttle body. Tried bypassing the fuel pump relay and no sucess. Read another post about checking resistance on the ect sensor. That was within range. Could this be a low oil pressure problem? Has good oil pressure when running (have to spray fuel into throttle body while cranking to get started) but how can I test the oil pressure switch? I don't want to condemn the ICM just yet but that's my next step
have the same problem?
