my best friend is in the hospital and his gf is trying to make it back and fourth to see him but her jeep is having some issuses and im tryin to get it fixed for her. It has been an on going problame for the past few monthes she can be driving along and then come up to a stop sign and as she starts to slow the jeep begins to spudder and dies. Then ysterday she was on the interstate doing 60 and it completly died on her. my buddy replaced the fuel pump two weeks ago befor he whent into the hospital and it ran fine till yesterday i was thinking maybe a cps could be goin skrewy on it like my 89 did but just want to get some advice befor i get home today to work on it i dont want to just start throwing parts at it but i realy need to get it figured out befor she makes the 2 hour drive back to see him tomarrow. Any advice would be appriciated

What's missing when it dies, fuel or spark?

Any other symptoms, like loss of lights etc when it died on interstate? And sudden death, or bucking and choaking first?

Several things can be in play, the CPS could be a possibility. On a background of sudden cut out: either no fuel or no spark, and a new fuel pump (brand?) has been installed, also check and refresh all grounds, check connections as a benchmark.

when it was dieing when coming to a stop it would spit and sputter then die or somtimes it would just spit and sputter then pick back up it almost acted like it was flooding out but on the inter state she said it just cut off with not hesttating or anything i cant tell whats missing when it dies becouse u cant duplicate it it just does it randomly the fuel pump came from napa and the fuel filter was replaced at the same time

Whats the fuel pressure in psi? Is the pump wiring shady?

its round 47 48 all the wiring is good i replaced the crank sensor last night and the pic up under the distributor cap and it seems to be fixed now ill let ya know if the problame comes up agien thanks for the help

Those pressures look pretty good. Curious to see if the cps and cam sensor replacement fixed it. Good chance they have
Let us know.

well so far she has put 180 miles on the jeep and it hasnt died or sputtered since i replaced the cam and crank so im not sure witch one it was but it fixed the problame

Sounds promising
