Ok i have a 97 xj and it wont run. Last time it ran it would run fine then after a while driving it would shut off if u hit a bump or stop, but would start right back up. Then one day it wouldnt start at all and just turn over. So i replaced fuel pump, cam shaft sensor, crank shaft sensor, new plugs and wire what could it be. Its been down for a year and i am baffled. Can it be the computer or what? Please help im tired of looking at it and wanna play. Thanks

Does it have spark?
What's the fuel pressure in psi?

"Its been down for a year and i am baffled."
Have you considered taking it to a shop for service?

Sounds like a wire has chafed and is opening or shorting to ground when the engine moves.


Examine all wiring in the engine bay for chafing through the wire loom to the wires within.


The wire loom exiting the fuel injector plastic manifold on the left side of the valve cover has been known to chafe on the fuel rail.


Examine the Crankshaft Position Sensor wiring closely. It has been known to chafe on the intake manifold.
