The jeep is getting fuel, but not getting spark. I put in a new cap, rotor, coil, and distributor in, still nothing. the cps is the only thing i haven't replaced(it was done 8 months ago), if that isn't it, then im fresh out of ideas. any body know what it might be

Well... It could be the cps again.. Sometimes new parts just have a random flaw that causes premature failure. Get a code reader on it maybe? What else has been done to help diagnose/narrow possibilities? Does it crank at all? Turn over at all?

its cranking but not starting, it just cut out on me when i was driving, i pulled over, waited a little started it ,then every time i tried to hit the gas, it would die

If it starts at all, it's not the cps. Sounds like another sensor, maybe TPS or an o2 sensor.

Edit- have you load tested the battery and alt.?

coyote1

it's not running, an 02 sensor wouldnt have anything to do with it not starting, neither would the alt

What year is your jeep?

Crank sensors usually are all or nothing but NOT always.

Especially with aftermarket crank sensors. They are not exactly known for their reliability or longevity.

You mention it's not getting spark. That means the crank sensor is a primary suspect here.

And if you replace it, buy it directly from Jeep......well worth the extra money.

if yours is a renix era...my other jeep had an issue that i was not able to track but my buddy i gave it to found out that is was the connection between the computer(inside the cab) and the wiring harness outside in the engine compartment.he got it running and drove it for a year and then he blew it up and now i have parts

its a 94

have you taken out the coil and tested the oms resistance? and with a voltmeter check to see if you are getting power to the coil
