Hi Guys! I've scoured these pages the last couple days, but can't find anything that matches my specific dilemma. I have a 1990 Wrangler w/ 150k miles on it, recent acquisition by my future son-in-law. It was running relatively fine, but it quit suddenly on a recent trip. It started cutting out when hitting bumps, then finally quit altogether. After dragging it home, hitting the forums, swapping a few parts, following all the sensor tests and wrapping my head around this TBI setup, I am afraid I have a partially dead ECU. -All ignition parts replaced- Ignition Module, Coil, Wire

Hi all, I am new to this forum, and to Jeeps in general. I recently got a 1990 Comanche 2wd, with the 2.5 TBI engine, and over the past few months have been trying to get it going. It was parked for about 10 years due to a bad transmission, and possibly the issue that I have now encountered. I am going to try to be as thorough as possible, but I am stuck and need some outside eyes. My dad is a professional mechanic with his own shop, so I have tools etc. at my disposal, but this thing has both of us stumped. Issue: I replaced the fuel pump and tank, flushed the system, along wit
