Good info!That appears to be the oil pressure sender connector though it seems further to the rear than it should be. Could be that I'm having a little trouble getting oriented from the photo. Can you get a photo looking down onto it from the top?
The engine would not stop with the oil pressure sender connector disconnecting though it would cause a red Check Gauges light together with a zero oil pressure indication if it came unplugged.
I did, and I think he said something like you might be getting only 10psi when the specs could be between 40-50psi.Had you told your stepdad that someone already checked your fuel pressure at the pressure test port right after the engine stalled and pronounced it ok before he said he thinks the fuel pump needs replacement?
I just bought one off of Amazon, anyhow I hooked it up to the Schrader Valve and fired it up and its right at 50psi. When I turn the key to run, the psi jumps from 0 to 49 and after 5 minutes its at 22psi.The pressure is supposed to be very close to 49 psi. Borrow a fuel pressure gauge from Autozone (they're free to borrow after a making a refundable deposit) and verify what it is before buying a fuel pump.
I bought the Bosch Fuel Pump but have not installed it yet. Those readings were with the existing situation.A fuel pressure regulator only limits the pressure to no more than about 50 psi. It would not be the cause of low fuel pressure which would be caused by a weak fuel pump.
Did you install a Bosch fuel pump as is recommended or was it a store brand or aftermarket like an Airtex or Spectre?
Sounds like it to me. Make sure your gas tank is as close to empty as possible before dropping it. Also be aware some of the plastic fittings on top of the gas tank will be brittle by now so be careful so nothing breaks.I bought the Bosch Fuel Pump but have not installed it yet.

Does that sound like its the issue then?
Turn key to Run, pressure hits 49psi, then slowly drops to 25psi over 5 minutes = bad fuel pump?
OK so little update here,Sounds like it to me. Make sure your gas tank is as close to empty as possible before dropping it. Also be aware some of the plastic fittings on top of the gas tank will be brittle by now so be careful so nothing breaks.
That confused me, there is no run position on the ignition switch. And when does it drop to 44-43, when the engine is not running?With key turned to Run, pressure hits 46psi then after 2 minutes it drops to 44-43psi and does not go lower than that.
With key turned to On, pressure hits 49psi and holds strong there while running.
Oh "run" I was told was the notch right before starting it, with not starting the Jeep I can hear the fuel pump start and the psi jumps to 46 then slowly drops to 43ish.That confused me, there is no run position on the ignition switch. And when does it drop to 44-43, when the engine is not running?
But it holds steady at 49 psi when the engine is running? If that 44-43 psi is even after it sits over night, that sounds ok.
Still can't say why the engine stalled at the stop light, not sure where to go next with this.
That all sounds fine so long as it doesn't drop much below that 43 psi after it sits overnight.Oh "run" I was told was the notch right before starting it, with not starting the Jeep I can hear the fuel pump start and the psi jumps to 46 then slowly drops to 43ish.
While engine running its right at 49.
Did you ever find the solution to your issue?? CPS or fuel pump? @tomtaylz seems to have the same problem.Ok "hoping" someone might have a suggestion or direction to go with this.
We were driving to the store tonight, hit 40something mph and the engine cuts off. We are now coasting down the road towards a stop light, I have no power steering, brakes are hard to depress, but still have all electric in the cab so I throw the hazards on. I shut the Jeep off, and try to restart it, and it just cranks and never turns over. I repeat this a few times waiting a couple minutes in-between attempts.
Just then, another TJ rolls up next to me and the guy says, "you alright over there?", so I tell the guy it just won't turn over and we stalled while driving. So he pulls over in front of us and gets out, then one of his buddies tools up across the street, and seriously asks if he can check the fuel pressure, like they were familiar with things like this, and he says there is good pressure up there on top of the engine through this little valve. The friend also actually had a scan tool so he plugs it in, thanks the Jeep for having the spot to plug it in being so conveniently located, and says its not throwing up any codes at all. The check engine light has never came on, so he says to me that usually when theres no codes and the Jeep dies, "its something stupid" causing it.
I have no idea where to go with this info besides calling a friend or posting up here in the hopes someone might have an idea or if this has ever happened to anyone before.
Any insight is greatly appreciated!
Are we talking of the problem that I had when I started this thread or the problem that was still present at the end of the thread?Did you ever find the solution to your issue?? CPS or fuel pump? @tomtaylz seems to have the same problem.
Sounds more like your initial problem of having the engine shut off while driving. Here is a link to his post about the issue.Are we talking of the problem that I had when I started this thread or the problem that was still present at the end of the thread?
I only ask this because there was multiple issues that have all been resolved and i'de like to give you or @tomtaylz the best info.
