Hi there. I own a 1986 Jeep Comanche Custom 4x2 pickup with a 2.5 Throttle Body Injection or Fuel Injection. Last week Friday, I was heading home from the truck stop, where I parked my semi truck for some home time. At first my truck was running great, filled up the tank with unleaded gas, packed up my belongings on it and drove home. While I was heading home on the freeway, the engine gave up, so I shift to neutral, started up again and it ran for a split second. I decided to safely pull off the side of the road and get help from AAA. I was towed to a shop, where a tech there has moderate knowledge and experiences on AMC Jeeps. He found out that there was a faulty fuel pump, so that was replaced. He ran it for 10 mins and it seemed great, until he was ready to drive off from the bay. It stalled, he tried to start it, but no improvements thereafter. He checked the fuel pump relays and they're good, did a spark test and it showed spark from the plugs and wires and the ECM is good. He took apart the TBI and cleaned it, but he didn't looked into the injector and checked if the injector jet worked. He's about this close of giving up, but I advised him don't. I'm thinking of 2 things: One the computer may be bad or two, the injector gave up. Other than that I don't know what else can be the cause of that stall on the Last Friday's drive on the freeway. Thank you very much for hearing me out.
