have a 1997 xj 4.0 automatic, recently its been hard to start, I have had to put the pedal to the floor while turning it over... And the fuel gauge reads empty after I filled it up. Now When I hold it to the floor and attempt to fire it up its starts barly, turning over and shaking terribly only for a second or 2. When I check the fuel pressure test port fuel squirts out... Does anyone have any ideas?? Any insite will be appreciated

 

You are confusing the computer. The computer does not need any mechanical input from your foot to start the Jeep. You have a bad fuel pump ground and that is why the guage is reading wrong. Ask me how I know.

how do you know?

 

The pedal to the metal position is used on OBDI and II to clear a flooded engine. He is telling it that it has flooded, which may not be the case. The coputer as Blue said is set up to start the engine with no throttle engagement.

 

U say it runs rough and then dies or u get it started and it runs rough then smooths out. or it run rough when u drive it down the road?

 

Where was the ground that fouled on yours?? I'll start there save me from searching.. Thanks

runs rough for a few secs and dies, now it wont start at all.

 

It was just the relay... Easy fix for once
