Well, this problem is still occurring after changing the ignition switch. It's happening a little more frequently now and I haven't noticed it happening in a turn anymore.

I guess I'm going to have to replace the cps and see if that's the issue.

I'm at a loss.


I swapped out the cps and the issue is still occurring.

Any ideas as to what it could be?

The only thing left I can think of is the FP is cut'n out.
Replace the fuel filter and open that filter up looking for crud.
The fuel rail needs XXX amount of fuel psi to 'fire' the injectors. Have the rail ck'd for pressure amount. What is the min needed for your system to run?
What dia is your fuel line? I would want a min of 3/8" steel line from the FP to the rail.
How is the ele. to the FP fused? If it's a circuit breaker that auto-resets, that may be the issue.
When the engine quit. Were you pull'n or coast'n?

Check all grounds, battery cables, and wires going to coil. Make sure all is secure and clean.

It dies when pulling and coasting.

I guess lll get a new fuel filter and check the old one.
The fuel line is 3/8. The pressure should be around 40 psi.

I've driven it around 1000 miles since the swap and had no issues until around mile 900 or so.

Still SWAG it's the FP. Tho when most FP's goes bad, is just quits......
Have the rail psi checked.
AGAIN-How is the FP electrical circuit protected? Fuse or what??
Have you called the tech's who made your set-up and picked their brains?

I'm not sure how its fused. I only have one main fuse in my harness.

I'll get the psi checked.

I haven't called hesco yet, but I will do that this week.

What's SWAG?

On the cherokee forum ( I posted there because of the engine) a poster suggested a clogged fuel sock in the tank.

Do cj's have a fuel sock in the tank? If so, do I need to drop the tank to change/ inspect it?

yes they do, here is a real bad one....
if you haven't, check the wires going to the CPS they can touch the exhaust and short out

Is there a link to how to get to the fuel sock and change it? I guess I'll have to drop the tank. Any advice on that? Would it be wise to change the pick up tube while I'm in the tank?

I'm going to pick up a new fuel filter and inspect my old one this weekend.

Also, I've tried hesco but they weren't in at the time. I sent a pm to them and will try back.

I talked to hesco and they suggested that it might be the IAC valve. I changed that with no luck.

Still haven't been able to check the fuel pressure or the fuel sock and filter.

I tested the fuel pressure and its holding at 35-40 at all times.

I've noticed lately that a lot of the time it's dying when I shift it into reverse. It still dies in drive, but it happens a lot more when I shift into reverse and try to accelerate.

How close is that steel fuel line to the exhaust?
