    more fun with wires!

    Car was running. I wrapped the wires. Car will not start, but gets spark. Unwrapped wires, looked for any, and all wires/connections that could be bad, and replaced them. Looked at wiring diagram for possible missing grounds, and incorrect wiring, found none. All wiring now looks good. All...

    Bad ECU from the factory!!?

    I used the ECU from AutoZone. I sent the 2 Summit ECUs back for refund.They failed diagnostic tester. The AutoZone ECU is blue. The Summit ECUs are orange. The fit on the aftermarket distributor connector is better on the orange ECUs. Unfortunately neither one worked despite being the exact same...

    Bad ECU from the factory!!?

    Switch was good. Traced wires. wire to ballast resistor had a brown wire with a tracer connected to it for no reasonand then tied into resistor wire.Also discovered cracked connector at ampmeter. Turned over w/stock distributor. It fires but doesn't stay running. I decide that as long as the...

    Bad ECU from the factory!!?

    OK got spark to plugs. Ran 12V directly from battery. Removed 12V from fuse box. Turned over with starter relay on fender. It has got to be the ignition switch. I am going to pull and inspect/clean, and try again later. If no start... I will replace.

    Bad ECU from the factory!!?

    Added wire from the fuse box got 12V to + side of coil. Remove wire, and nothing. I also have spark from distributor.(found that the electronic distributor was no good not producing spark), I also found a bad wire to the sensor on the intake manifold) So now I have a coil, and a distributor that...

    Did not fire. Gave coil 12v does not fire. Checking ignition switch next I guess.

    Changed back over to original distributor. Came in to check thread before attempting to start. Did not yet switch from "hot coil" to original. Eliminating ECU for now.

    Bad ECU from the factory!!?

    I have a points type distributor that I can put back in. Do I go back to stock coil? What about the voltage regulator? What are the symptoms if it is not functioning properly? I have a solid state aftermarket replacement in the car at this time. The car turns over but does not start. It does not...

    Bad ECU from the factory!!?

    OK First check coil resistances. Primary is between 1.3-1.8 secondary is 1.998. Blue wire from ballast to + side 12V. blue ignition wire hooked to + side 12V. Black tach ground, and black and yellow wires to - side of coil. To be extra careful; after everything that has to do with removing wires...

    Bad ECU from the factory!!?

    Possible,but I don't think so. When it turns over it seems normal. And when I said adjusted the rocker arms; I was embarrassed to admit that when I put the rocker assembly back together; I had the lefts on the right, and the rights on the left, but only on one side. I then torqued the assembly...

    Tomorrow I am going to go over everything, and I am going to keep a log of everything I do from start to finish. If the thing does not start after all of my efforts; I will post the log, and maybe someone can point out what I do wrong, or don't do, or anything. I really appreciate all of the...

    Bad ECU from the factory!!?

    Exactly what I was thinking. So I tried the box. Car still does not start. Took box back to Advance Auto Parts to recheck. Box is still good. Now that is isolated as not the problem. Can the coil still be bad despite passing primary, and secondary resistance test? What other checks can I do...

    Bad ECU from the factory!!?

    Dig this! I just got back from Advance Auto Parts. I had the ECUs tested. They were all bad! Tested one off of the shelf. It passed! I bought it, and am about to install it. In conclusion: I received 2 ECUs in two days new in box direct from Summit, and both were junk, and cost $4 more each (not...

    Bad ECU from the factory!!?

    Already checked those wires both with key on, and off, and verified that they are wired accordinding to diagram/instructions. Plug to ECU is only a year or so old, all wires are like brand new. If ECUs turn out to be OK; I will probably go after HEI distributor next.

    Bad ECU from the factory!!?

    Worked on today. Changed out bad wires checked, and added ground wires. Fixed possible short near ampmeter gauge.Checked reluctor with brass feeler for the 10th time. Checked coil; coil is good. Used 2nd coil, and measured primary, and secondary resistance on both. Both measured the same...
