after filling up at the gas station, randomly my '88 cherokee 4.0L starts and runs for about 5 seconds and dies. fuel pump working, fuel filter clear. egr has been bypassed for some time but has never given me problems. after removing filter and draining lines, now runs for about 25 seconds and dies. possible fuel delivery problem, or sensor(s) or computer?? getting plenty of pressure at fuel rail. a lot of hesitation when it does run. any help would be appreciated. thanks

are you getting a check engine light?
