Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Have your idle air control solenoid checked.This controls the idle at the proper computer outputs.

Why does 1992 isuzu trooper runs for a few seconds then stalls and won't keep running? I've replaced the fuel pump,fuel pressure regulator,and fuel filter. Spark plugs and wires have been changed also


hot or cold engine or both?





which engine, to work on one, you need to know what it is

and what EFI system it uses. or its all just a crap shoot.

no new distributor cap and rotor why skip the full tune up,. why?



first questions.

1: can you save the stall with a a fast right foot.

2: why change out pump etc, if fuel pressure is at spec, a $20 tool would have saved you 5 hours hard labor and bath in fuel? why?





Stalls 101.:



the engine can stall for over 50 reasons are you going to do all 50?

surely not. why not consider diagnosis.. as a path.

1: car stalls, right foot saves it. and can drive fast if i keep foot busy.

a: ISC stuck closed.

b: EGR valve stuck open (depends on which engine options)

c: low compression on one or more cylinders.

2: can\'t save it from stalling (right foot)

a: fuel pressure is low. (wires bad.)

b: lost spark, for any reasons.

c: lost 12vdc to the EFI system( killing spark and fueling)



stalls.

hot or cold or both

stalls, can save it or not, hot and cold

hot restarts are easy and it runs good hot,yes./no.



there is lots more to it, then just stalls. lots more.

Check your fuel pressure it should be 60-66 psi with key on engine off.If its not within these specs then replace the fuel pump and filter.Sounds like the pump might be weak.
