Newbi to Jeep Forum. Great site to harness a wealth of information for DIY repairs.
When feasible I would appreciate if all the 1000 years of experience in Jeep industry could weigh in on there thought regarding the following issue:
Issue. Driving 55 mpd down the road and the engine coughed (like i was running out of gas) a few times and quit running. Would not re-start. Towed it home and checked the following:
1. Attached fuel pressure gauge to fuel rail and it reads 40 psi when key is turned to power (Not positive if this is the correct terminology) after 1:45 fuel rail pressure decreases to 0.
2. Disconnected and reconnected both crankshaft and camshaft connectors (X3), still doesn't start.
3. Swapped fuel pump relay with a good known relay.
4. No check engine light before engine quit.
5. No codes when I checked also.
6. There has been no modifications done to the engine or electrical system for the past year.
Question. What should be the fuel pressure at the rail and would it be constant??
Jeep Specs: 97 JEEP WRANGLER TJ, 4.0L, Manual. 116K miles. My Mods: Swapped to DANA 44 G2 Core, 4.56 Disc brakes (Rear), re-geared front to 4.56 and chrome molly axles swap, Rubi 3.5 Suspension w/shks and swapped rear track bar, HD-Y-Link steering kit, Brute force Diff covers (front & rear), 33" AT sport tires.
Thank you in Advance, Larry
