    Stalls randomly, No Spark, Not The Distributor

    Hello and thanks.
    Ive owned 4 Cb7's over 10 years and never had this happen.

    Short story, car runs and stalls and runs and stalls. Dash lights are on, and its getting fuel but no spark. And its not the distributor because i swapped that and no luck.

    Here is the long story:
    So it just stalls out while driving home from work. I check that its getting fuel first and its good. So move on to spark, No Spark. I give the distributor housing a smack with a rubber mallet and she starts. So this morning I head to pick and pull salvage for a distributor. I put it on and the car starts for 2 seconds and thin stalls again. This time it wont restart. So I put the old distributor back on and it starts. I drive around my block and it stalls. This time I just pull the key in and out and it starts. next time it stalls this doesnt work.

    Please Help, I gotta get it running this is my only to work.
    Thank You

    main relay or ignitor in dizzy



    how are you checking fuel pressure? can you confirm the pump is actually running when this happens? if it is, id be leaning towards ignitor. if not, prolly main relay.

    at least thats where i would stsrt

      I would start with a new distributor. You do not know why that particular car was in a wrecking yard. I have had a similar problem in the past with my car and it turned out to be the distributor. I had to replace it twice with new parts (different issue with new distributor), so never assume replacement parts, new or used, are good if you still have a similar issue after replacing that part.

      For spark in our cars, you should look at the distributor (cap, rotor, ignitor), the coil, the ground under the thermostat and the ECU. But since you said that if you tap the distributor ti will run, that would be my first go to.

        Im checking fuel pressure by loosening the nut at the fuel filter and turning the ignition to the on position. The fuel pump primes and fuel sprays out.
        I already swaped the dizzy. It started, ran for 5 sexinds and wouldn't start again. Put the old one back on and its back to running and randomly stalling. So figure ive eliminated the igniter and coil.
        Im headed to the junk yard to pull a couple relays and ingitions.
        Thanks for your response. Any further insight or experience would be greatly appreciated.
        Thanks all!

          Than you. Your absolutely right. Ill swap another dizzy in first and check for spark at the coil as well. Yeah did the fallow back down the line but nothing was working from spark plug, to cap to coil. I also did put a knew cap and rotor on.
          Thanks again. Out door right now to get parts. Ill check back.

            Ok. Its was either the ignition module or the main relay.
            I just replaced both at the same time because they were so cheap at pick & pull, and I needed it ready for work tomorrow. Thankfully one was the problem.
            Thanks again.

              Pop the cover off the relay and look closely for cracks in the solder joints. If you have a small soldering iron, remelt the solder and keep it for a spare.

              I just had the relay in my 90 go bad, but I couldn't get it out of the car easily, so I left it there and simply mounted the new one much lower in a more accessible location.

                i vote towards ignition unit (module)

                below is what i changed out due to similar symptoms. my ride would die midway to work. after swapping out main relay, plugs, wires and distributor, i finally diagnosed it to my ignition unit. autozone tested it and it failed. swapped it out and it works. #7 is what i changed. on hondaautomativeparts.com, its called ignition unit. autozone calls it ignition module. so below is the picture so you can reference it and call it whatever you want. lol. good luck.

                  The main relay controls the fuel pump, so if you were getting fuel, it is likely not the main relay.

                  Glad you got it sorted though!
