ive got a problem with my xj. i was away on a trip and it staled out on me and wouldnt start. i had it towed to a shop and they did diagnostics.it came up as ect voltage too high, no cam signal , and no crank reference signal....I have had it all fixed and it drove home fine till the next day and now its staling out on me again i cant figure out whats wrong with it and i cant afford to keep getting it towed can anybody please help me

the work should be warrantied, take it back, ...sounds like a faulty sensor/code was diagnosed, WHAT DID THE WORK ORDER SAY ble for 1WHAT WAS DIAGNOSED/REPAIRED/REPLACED?.... Try taking off battery negative cable for 15~+ mins and reconnect, prob won't help but, may reset the ecm and no start...

all three sensors were replaced

Is the check engine light back on?

If the shop replaced all the sensors and the problem still persists, next I would suspect the wiring or maybe even one of the new sensors is bad.

The wiring to the crank position sensor runs close to the manifold. It can be damaged pretty easily.

no now that all the sensors have been replaced the check engine is not on i just drove it home from the shop and it ran fine i got back in it to run somewhere real quick and it staled out on me again no check engine lite. it started back up again a lil bit later but only to stall out again it starts up fine after sitting for a few hours but i dont know why it keeps staling out. could it be the fuel pump getting ready to crap out.

check the pick up in the dizzy, it might be that. if you suspect the fuel pump, turn the key to on position, u should be able to hear the pump humming in the gas tank, if you are not certain about the pump noise, pop your hood, unscrew the valve cap on the fuel rain and press the valve, if it shoots out a strong stream then your pump is good. there are alot of things that can cause engine stalling, u just need to keep trying (from the cheapest repair/replacement and work your way up

i meant *fuel rail*

im just having a hard time with it cuz its my only vehical and i have spent pretty much all the money i have on this jeep.

Could be a defective crankshaft sensor. I had one replaced and it was bad ( I guess they have a history of being crappy).
The shop replaced it with a new one that has worked fine ever since. The shop did not charge me for the new one since the other was defective.

get a fuel pressure gauge and hook it to the fuel rail, try to put the gauge in a place that you can see from the driver seat and tape it in place so that it wont interfere with closing the hood. now go for a drive and see if the fuel pressure drops while driving if it does then you have a fuel pump problem, if not then youre all good. go put the gauge in your special tools drawer. then go get an obd II scanner with data stream capability and go for a drive. monitor the signals from the crank and cam sensors there have been cases where the sensor rings have gone bad causing a wierd signal and making the engine die. also just a side question is this only happening after the engine is shut off and all you hear is a loud click? or does this happen during driving cycles?

[phillyxj570]

it either just wouldnt start up or it would just cut out while driving. i have alread did what you said. i took it for a ride with a fuel pressure gauge hooked up and it was the fuel pump. it staled out on me on the side of the road i had my buddy run me to a auto store and i replaced it rite there where it staled out and it has ran flawlessly ever since ive had it fixed for bout two weeks now
