I chaged my fuel filter out. Its not my fuel pump bc i have pressure at the rail. Im not getting any gas into the engine im thinking a bad sensor somewhere. Any ideas would be much appreciated

 

then that means ur injectors are not pulsing check ur CPS its common failure.

 

Bought a new cps at autozone put it n tomaro n see if that does the trick. I sure hope so

 

Had the same same issue on my 88 went in some real deep water it fried the CPS and trouble shot it and that is why it ended up bein. So Hopfully it solves ur problem.

 

i just changed the cps out for a new one. nothing changed still tries to start but doesnt turn over even with starting fluid, so that made me look at the plugs. NO spark? dam jeep. so now im considering control module or coil. any further help by anyone would be awsome.

 

gotta do the quick checks

1) fuel?
2) spark?

spark is super easy to check so look at that and check back.

fuel isnt too difficult either. I like to probe the injector wires first to see if its getting a signal. if it is then 99% of the time they are working

 

Why don't you start by telling us what your original problem is/was.... have you had the computer codes read?
No Spark, check battery, cap, rotor, wires, coils, Cam position sensor and crank position sensor.
No fuel, pull a injector, crank motor is it spraying fuel. Check fuel pressure, just because fuel spray at the rail doesn't mean there is enough pressure to run the motor.

 

I was driving n the engine jus cut out is what happend. But i have no spark.

 

Problem could be in the coil ive checked and replaced all the other things you listed

 

do you have a multimeter? You can probe and check to see if you are getting a signal to the coil. You should see a voltage change as the coil is "fired" by the ECU. if you are getting either constant voltage or no voltage, then its not the coil. if you are getting proper signal but no spark (check if the coil wire sparks to ground on the block or somewhere) then its likely a bad coil. coils going bad arent too normal, but with wheeling hard the vibrations/impacts can ruin it for sure

 

Ok ill do that. Would i have to take it out to test or just leve it in

 

Moved to OEM from Advanced tech.

 

either way is fine as long as you can probe the wires and get a reading. You can do that with the coil disconnected. to actually test the coil (not the leads but the high voltage side) it obviously will need to be connected

 

The coil wouldnt effect gas into the intake would it? Im pretty sure the no spark no gas to intake is connected

 

no connection. the computer sends a signal out to the coil to fire and forgets about it. If the coil doesnt fire, the computer has no idea.
