Haven't worked on the jeep in a while. Got an SRT4 so it's gotten most of my attention along with a bathroom remodel. Noticed my kick down cable was frayed badly, replaced it. Cleaned the interior up a little, test drove it and it would red line before shifting. 3rd wouldn't take until about...

Finally got around to this past weekend. Fuel pump is getting full battery voltage on cranking. I jumped power to the pump to help prime it on key on and it fired right up. I shut it off and it started a few times no issues, then it started taking longer and longer. I’ve realized if I pump the...

I’ve got to check fuel pump voltage. Got 6 or 7 other jobs going on right now ontop of the day job, I forgot to do that. Ack. I know I’m getting battery voltage on the out side of the pump relay. I’ll check for voltage drop. The pump has a super short burst upon key on engine off. Usually pumps...

I’ll run a compression test. I just replaced the head gasket with a severe duty fel pro one. Followed torque spec and sequence, etc. I’ll be working on it a bit over the weekend. I’ll update you guys if I make any progress. Sent from my iPhone using Tapatalk

I’ll run with 4x4jeepmanthing’s injector comment and try to unplug an injector at a time to see if I get any change. Sent from my iPhone using Tapatalk

I thought the same about voltage. I charged my battery and even tried boosting it with a commercial booster (up to 250A , 6/12/24v) with no change. Sent from my iPhone using Tapatalk

Not arguing your advice, but I am curious as to why it would run perfectly after it finally gets started if the pressure was low? Sent from my iPhone using Tapatalk

Ether (starting fluid) ignites more easily than gasoline. I seem to be getting consistent spark from the coil and distributor. Also, 4.0L auto trans 4wd. Sent from my iPhone using Tapatalk

My apologies. 94 Cherokee 4.0L. Haven’t ran a fuel pressure test on the engine. Just verified fuel delivery. Occasionally it will randomly start on its own with no ether assist. But then you run it a while (not driving, just idling in driveway) and then as soon as you shut it off, won’t start...

First time poster, first time XJ owner. Jeep won't start. Cranks all day, shows only code 12 and 33. Fuel pump kicks on for about 1/2 second when ignition is keyed on, Schrader valve releases decent fuel pressure. Unplugged MAP sensor, checked ASD relay, checked fuel pump relay. I understand the...
