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 isand 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 bothstalls, can save it or not, hot and coldhot restarts are easy and it runs good hot,yes./no.there is lots more to it, then just stalls. lots more.

Procedure for replacing sensors
depends on the sensors most disconnect the battery replace the sensors should reset itself if not any trans shop can reset them
Need to replace lower radiator hose for 2002
these things must be done very carefully-try to get the fan/shroud assembly off and out of the way-you may have to go from underneath-removing the lower engine shielding-Denny
Engine cranks and tries to start but wont
I would first pour some gas in intake if it fires or runs a little could be fuel filter or fuel pump.if it don't fire pull a plug out and crank see if theres spark that's where id start
