SO, I just went out to my jeep and it wouldn't start.

I can hear the fuel pump engaging and the engine cranks and almost catches, sputters for a few secs and dies.

CPS maybe? What other things could cause this??

Johnthepanpire

It's a new fuel pump, already drove 60+ miles on it with no problems.
Starter is a few months old (but it cranks fine, just no start)
Plugs, coil, dizzy all that stuff is new.
I just did a tune up a month ago with just around the town driving so it's not any of that stuff.

I would get in there and test your CPS. It could for sure be responsible for your crank-no-start troubles, especially since you've recently replaced most everything else that could be a likely cause.

Out of curiosity, what brand fuel pump did you install?

F1Addict

Also, an audible fuel pump is no guarantee that it's delivering enough fuel pressure to squirt through the injectors, you might want to check pressure at the rail.

Johnthepanpire

I was planing on doing that too. I don't think it's a pressure issue but we'll see tomorrow.



Any other ideas in the meantime?

It's a Performance Electric.

Ok just tested the CPS, resistance was fine (0.0 Ohms) but when I checked the ACV on crank I got .2

From what I read on here about testing CPSs, mines fried. Correct?

cruiser54

Yep. If you checked it for AC volts with it unplugged from the harness.

Ok got the new sensor, but, HOW THE HELL do I get it off?! I can't get anything up there with enough space to turn!
Would a universal joint work, if so what size?

Johnthepanpire

Nevermind, I found the thread on here

New cps, still no start. Same thing as before.

I'm really starting to get pissed off and I need my jeep back

Could be your coil or the cam shaft position sensor.

Johnthepanpire

It's a new coil and can I check the cam sensor, if so how?

Johnthepanpire

It barely sputters a little bit and dies. Could that be a fuel pressure problem?

Keep the ideas coming everyone

cruiser54

Yes it could. Did you check the new CPSs output?

The sensor in the distributor doesn't keep a Renix Jeep from starting like the later models. You can unplug the dizzy on a Renix and it will run.
