I spent yesterday and today changing the upper gaskets on the truck. I made sure to mark the distributor, followed all directions, then put it back together (almost). I could not remember where the ECT sensor I had removed the terminal from was, so left it hanging. Maybe I got a little antsy, but I wanted to hear the engine fire up and run. I double checked all nuts, connections, etc and fired the engine.
It cranked, fired right up, sounded great, then shut off after about ten seconds. So I fired it up again, it started, but this time it had a really bad knock in the engine. I found the ECT sensor (thinking that might have been the cause), plugged it back in, but no luck. The engine will not throw a service engine code when left running for a few minutes. I do not want to leave it running much longer than three to five minutes because it sounds so bad.
have the same problem?
