    Well he was back on the road until Monday evening. When he returned to work and went to start it, it fired up and stalled several times. He applied a little throttle and it backfired then continued running. While on his way home he lost power and it then stalled and could not be restarted. He had it towed home and that is where is currently sits. The previous owner had it converted to fuel injection. I'm not sure as to the system which was installed. First thought which comes to mind would be fuel filter and/or fuel pump. Any ideas as to where to begin would be appreciated. Thanks!

    First thing would be to spray starting fluid into the intake. If it fires right up and then does after burning it up then after checking all the injectors, trace the lines all the way back to the fuel pump to check for leaks. If you still havnt found it then check for voltage at the pump and pull the pump. I had the same thing wrong with my TJ and with the pump out sitting in gas, when I primed the pump, it would whirr but not send fuel to the hose.

    I thought the 85 came stock with a mechanical pump and I'd assume since it was converted to EFI it would need to have been switched to electrical. Do you think is a correct assumption?

    I would think so yeah. Just check off the easy things. Spark plugs, spark plug wires, battery, alternator and then start at the intake and move back to check if it's the fuel system.

    Sounds like a conflict of interest...

    For who?.... He had a mechanic buddy come over and determined it was the fuel pump. That will be on his to-do list.

    Well he's having issues with it again. An 87 CJ probably wasn't a wise choice for someone without the time or ability to troubleshoot and make necessary repairs. He's thinking of selling it again. I'll keep everyone posted so if anyone is looking.

    That’s a sad moment, definitely a good idea to have some sort of knowledge about Jeeps to get involved in that sort of project...

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
