On a 1995 jeep wrangler 2.5 manual tranny with no a/c when you try to start the jeep the starter turns over but the dash lights dont come on the relays dont energize for the ignition or the fuel pump so...


Look for any ECM fuses in the fuse block.Wiring diagrams are available online but difficult to find for Wranglers. (WHY?!!). Schematics can be found in the back of any Haynes or Chiltons manual.I haven't had this problem yet but will watch to see what you come up with. Good luck.

Engine hesitates when starting in first and when throtlle depressed 1/4 inch or so


Check all vacuum hoses for small leaks, check throttle position sensor and map sensor, possibly intake air temp sensor as well. Instructions for that can be found in most inexpensive manuals such as chiltons or haynes, you can also have codes scanned at most larger parts stores. Use digital multi-meter for individual component tests.
