I am also working on a 2002 isuzu axiom with the 3.5 engine that also starts for a few seconds then shuts off and will not start back up i did an engine over haul on it, and the engine ran before i removed the engine, did you find the problem?
ok i have a 1998 durango with the 5.2L 318 engine. had trouble with a bad cell in my battery. I went out bought an optima red top battery for it 800cca. put it in and had same trouble. No start without putting foot on gas. wouldn't stay running without holding foot on gas. CPU has to relearn it's programming once you unplug it for long periods of time. mine was without power for about 2-3 weeks till i got new battery. Start with this.. first check under air filter make sure a squirrel hasn't made a mess under your air filter and it's clogging the air intake. Then pull off the lid to your injector cover ( the screw down lid coming from the air box ( with air filter in it) to "carb") make sure all your cables move freely. put that all back together and close hood. Start truck with foot slightly on gas pedal to get started. keep it at about 1k to 1500 rpm for about 1-2 minutes. Rev motor to about 2500rpm and let it die out if it will. Get out lock doors with key fob if you have it. if not make sure to lock doors. ( trust me it worked for me) let sit for 5 minutes. come back out and unlock door and relock door 3 times with fob ( if you have it ) or key if you don't have a fob. Then unlock it with the key and enter vehicle. Start truck as before and keep it around 1k to 1500 rpm again for about 30 seconds rev it up and should keep running. Mine did. I think the iac was stuck from sitting and has now since loosened up. Good luck hope ti works for you.
Your fuel filter may be at it's life time and will need to be replaced. Start with the simple and replace that, the other thing also that would cause the engine to shut down would be a faulty oil pressure sending unit. What is the oil pressure on the dash when the engine shuts down. You need at least 8 PSI to have the engine stay running. Check your Fuel pressure at the shredder valve and you should be 62-65 PSI with the engine not running and fuel system energized, once the engine is running it should drop about 5PSI. The last thing that could cause this would be a bad ICM, once the ignition system heats up the ICM fails and the engine shuts down. A mentioned, start with the simple and replace the fuel filter and check your fuel pressure to ensure your fuel Sending unit has not gone bad and will need to be replaced. Good luck and keep me posted.
you might have a regular key instead of a microchip key. the micro chip key sends the signal to the computer. If you have a regular key it will start and a couple of seconds it will shut off and do it over and over again.
