Engine Stalls

wes79 · Mar 29, 2004

Ok guys try to help me out. I have a 93 xj 4.0 with about a 118k. My jeep stalls when i am going down the highway. It just dies and sometimes it comes back to life a second later and sometimes not. If it dies completely it wont start for a while, It cranks but no fire. Recently if I wait a few minutes jiggle some wires around the distributor and the box that the center wire on d cap goes to. I have replace the fuel filter recently. I think it is something electrical.

Sounds like your Crank Position Sensor. Do a search for CPS or the like.

I'm putting $$ on CPS. Some say to clean connector and so on, I say replace it and keep the other as a last resort spare: mine did the same thing and it wasn't till I replaced it that I got rid of the problem.

btw, that box that that wire goes to is the coil.

dont jiggle that coil wire with the jeep running. if it pops off you could get a nice bone jaring shock.

check the hard vacum line that goes to the map sensor from the throttle body... it to could be cracked...

of course my money is on the cps also.
