  • HEI, External Coil, and No Start

    So I was driving along the hwy and the car lost power and died randomly. I had the car towed back. I thought the hei module was bad so I replaced that, still no start. I thought the coil was bad and I replaced that, still no start. Is it possible that my timing jumped on the hwy and that caused the car to shut off? Seems plausible but not likely. You guys have any ideas why the car won't start otherwise. Thanks for the help!

    Hey Venchei!

    So do you have spark or not? If you do not have spark -it can still be the crank/cam sensor within the Distributor. Have you tried swapping the entire distributor? It is possible to be jumped cam timing if your hydraulic tensioner is not in prime shape and if it jumped more than one tooth. You should be able to determine that if you have spark or not. You can still get spark with jumped timing.

    If no spark -there is also the possibility of a bad ECU. Have you double checked all of your HEI wiring connections?

      Hey Mike,

      Yeh I remember the last time I had a no start it was the distributor crank/cam sensor but the car wasn't on the hwy running when that happened. Connections look solid, I'll check those and the timing. Might be that crank/cam sensor again

        Check for spark first before you do anything else. That helps to narrow it down!

          I pulled the first spark plug and it has spark. On the first turn it sounded like it was about to start but continued to turn over.

          Time to check the timing.

            I have had 2 different Probes, both shortly after buying them, just up and die on me when I was driving out of the blue. Ended up being the timing belt both times. Good luck and keep us updated.

              So I've found out that the timing is correct and I have spark... I'm thinking my fuel pump or ecu is bad. What do you guys think? Here are some links:

                Well when you turn the key on, you should hear the fuel pump prime. Do you?

                With a bad ecu I think you'll get a code zero

                  Next thing to do is to crank the car. Shut if off and immediately go to the fuel rail and crack one of the 17mm banjo bolts to see if you get some spray.

                  P.S. Don't do this in your garage with a kerosene space heater going

                    Hahaha yeh that was an interesting experience... It's parked under a car port outside a friends house lol. Battery is dead so whenever someone returns I'll get a jump, start the car and see what happens but when I cracked the fuel rail barely any gas leaked out.

                    Update: No fuel coming to the fuel rail after cranking the car multiple times; moreover, I heard nothing from the fuel pump upon turning the key to the start position. So we may have solved the mystery gang!

                      You should be able to jump your diagnostic box if its a 93-95 to force the fuel pump to run. not sure about 96-97

                        Replaced the pump, still no action. Actually just tried this and I hear the relay clicking but the fuel lines are dry, so the new pump is not running, maybe I have a wire short but the gauge on the instrument panel is reading. Going to drop the tank again and check the connections. Am I missing anything?

                        Should've tested it while it was down... Yay, opportunities to learn!

                          After taking the tank down. I recorded this. Tested the 'faulty' pump and turns out it works too. So definitely a short but I have no idea how to trace it and fix this problem.

                          Furthermore, I removed the pigtail and ran the same current through it to the pump and found that the pigtail worked just fine; this is truly a mystery. Also found that the enertia switch wiring was modified with two fuse lines as placeholders (they weren't blown). I have to be missing something. Not sure what though.

                              Does the fuel cutoff light come on the dash when cranking? If so the inertia switch or whatever is left of it is bad.
