With full tank it was parked for 2 days. My wife leaves for work and makes it 1/2 mile before fuel gauge drops to E and jeep dies. I have 3.19v at the tps. It stays the same when I unplug the crank position sensor but climb to 3.26 when I disconnect the cam position sensor. I've read threads that say crank position sensor will kill fuel fire and Guage. Can someone point me in the right direction. I am starting to flatspin
You're on the right track to figure this out but you didnt say if you have a no start condition or not. The cam sensor can cause a no start as well as the the crank sensor. In your case, if it is a no start and based on what you posted, it sounds like something else is causing the problem.
Try the same test, but disconnect both O2 sensors and check the wiring going to them for damage.
What else might cause no spark no fuel. Pcm is only 25k old(jeep dealership ) dude on here said o2. They are only bout 8k old. I know they don't last forever but it has ran with them disconnected. Both. I'm stumped.
So is this a recent event ... running with the O2 disconnected?
Bout 4 year ago cpu went bad and delayed the coil output as a result of this the exaust system exploded. Split manifold, gutted cat,and opened the muffler up like a beer can. It has been back together and running great for almost a year
