Intermittent Fuel Problem

Every once and a while when I try and start my wrangler 94 2.5 yj. There is no fuel pressure and it has trouble getting a prime. I dump some fuel into the throttle body and it will fire right up and run for a few weeks. Last night it would turn over and want to fire but not enough fuel to get it to start. I poured some fuel in the throttle body and it would run only until the fual I poured in ran out then it would die. While towing home I put it in gear and it started right up. Today it started and ran fine. Has anyone evr had this problem? Could it be an o2 sensor? Fuel pressure regulator? Fuel pump going bad? Maybe a relay? I am at a loss.

possibly fuel pump, but you need to check power at the pump when its not starting. only way to tell whats going on. if power is at the pump, and no pressure, then the pump is bad.

if there's no power at the pump, then the pump isn't the problem

"The danger to America is not Barack Obama but a citizenry capable of entrusting a man like him with the Presidency. It will be far easier to limit and undo the follies of an Obama presidency than to restore the necessary common sense and good judgment to a depraved electorate willing to have such a man for their president."
