I got to enjoy my second experience with a cracked head on a 2000 jeep. I pulled the head with the intake and exhaust manifold still attached as I just could not get to the lower bolts on the intake manifold. I thought I was being clever and installed and properly torqued the intake and exhaust...

I've only had the Jeep a couple years so I don't know the history of the oil changes. I used Pennzoil dino oil but put in a heavier weight than spec. the last change to see it it would boost the oil pressure. It didn't. I did have to add a small amount coolant but I (incorrectly) assumed it...

I just wanted to share what I went through to diagnose the source of the low oil pressure in my 2000 with a 4.0. The engine has about 150,000 miles and has good oil pressure at start up and then the idle oil pressure drops close to zero when warm. Often it seems the problem is sending unit...

I received a computer from FS1 in December. It didn't work. I thought my diagnostic skills were wrong so I checked every sensor and harness and went through the troubleshooting manual. Again. I was sure the computer must be defective. On March 12 I did an "RMA". No response. I started calling...

I can't get this link to work - but it seems an inline check valve is not a strong solution: https://www.jeepforum.com/forum/f9/who-has-added-line-fuel-pump-check-valve-684229/index4.html Wish I would have seen these warnings before, I installed a check valve today but wanted to do some more...

Just a quick update. Amazon is sending me a replacement Delphi FG1353 at no charge. That's good customer service! I'm hoping the second one lasts longer. For me the toughest part of the job was removing and replacing the large plastic nut that holds the fuel module to the tank. So I blew $29...

Yes. If I cycle the fuel pump a bunch of times before trying to start the Jeep, it will fire. Its my understanding the check valve was part of the Delphi module I replaced. This is the part: https://www.amazon.com/dp/B00MBI3H7C/?tag=wranglerorg-20 It looks like the old Mopar part number for...

For what its worth, I installed a Delphi FG1353 in my 2000 Wrangler in July. It worked great at first, but after less than 3 months I'm back to the long crank problem. I bought it through Amazon so I'll see if they will warranty it, but I'm really not looking forward to doing the job every few...
