The engine could have jumped time, or you could have moisture inside the distributor cap.

SOURCE: shuts off while driving. no fuel pressure. pcm fuse blows/ fuel pump relay inserted.

Sounds like the fuel pump is shorted.

Did you check the fuel filter?
or possably the catalitic converter is cloged, check the exhaust pressure.

SOURCE: 97 jimmy wont start

Check for a bad distributor cap and or rotor..........a bad cap and or rotor can caues firing (cross fire)across the terminals and introduce spark to the wrong cylinders at the wrong time.......
hope this helps.....good luck!

You mean it will crank but not start ? Do you have normal compression, spark and fuel pressure ?
If the timing belt broke you won't have compression on all cylinders.

theres probably no sprak on it, try removing whichever spark plug cable and make contact with ground, see if it makes spark.. try this when u try to start the car only... if theres no spark, this means u need to replace the distruibitor..(where all the spark plug cables meet)

Hesitation while exceleration


Have these things checked for #1:

and the throttle position sensor, also have a fuel pressure test done, especially for the hesitation.

I would check the fuel lines themselves and make sure there is no blockage. If not you might want to check your fuel injectors and see if they need to be replaced. also make sure you didnt install fuel filter backwards.
