Jeep won't start, please HELP!
My 2004 Jeep Wrangler LJ won't start. I was driving down a washboard dirt road and didn't see a small washout. I hit the washout going about 25 and the Jeep quit. After some fairly thorough searching on this forum, I attempted the following:
Checked the fuel pump relay and fuel fuse under the hood (by swapping with relay/fuse known to be good).
Removed the crankshaft positioning sensor and tested with multimeter (results showed good, based on a forum post I found). I then reinstalled.
Checked for spark at each plug by pulling the rail and jumping with a screw. No issue with spark on the first three cylinders from the front of the Jeep, so I stopped.
Attempted to check fuel pressure, but the '04 does not have a port on the fuel rail. As I didn't want to cut into the rail or get too involved, I went with the starting fluid route.
If I spray starting fluid into the throttle body, the jeep will start, sputter and fail.
As I did not hear the fuel pump whirring noise when I turned the key to on (in addition to previous information), I assumed the fuel pump or regulator was bad.
So, I replaced the entire fuel pump assembly yesterday. The Jeep still won't start.
What am I missing?
The Jeep acts fine in every other way. The check engine light has not come on, so I don't think it's stored any codes. It will crank but won't start. I still do not hear the fuel pump whir when I turn to on position. When I test the wiring for the fuel pump, the multimeter shows resistance, so I assumed it was good. I am no expert with wiring, so I could be reading that wrong. I'd consider myself fairly mechanically inclined, and I can follow directions. I managed to install a Mopar fuel injection kit on a Jeep CJ years ago, so this type of work isn't completely foreign to me. I'm being as thorough as possible to provide any necessary details for proper diagnosis.
If we cannot find a solution, does anyone have a recommendation for a repair shop in Tucson?
