    After all the info in this thread, my guess is your ignition coil is bad. Do you have a spare coil to try?

    Or it could be a bad connection from the ECU to the negative coil post. That connection...

    That pretty much does says ignition is the problem. Did you also say your tach reads some RPM when cranking? That would also say the ECU is working since the tach uses the ignition coil signal as...

    I never really looked at my volt gauge when starting the car, so I just did and mine also shows a little above what your shows. I know the battery does not drop that much so it's just something with...

    The two pin connector from the pickup sensor near the drivers side firewall gets very corroded. Check that connector.

    FYI:

    The stock DeLorean ignition ECU and the Ford ECU Bill R run pretty much hold full dwell always. I updated to a GM module which has a very wide dwell change. That and a 1.5 ohm coil let me...

    Yes the frequency valve is on the pass side valve cover.

    All ignition ECUs (and point engines) break or connect the ground side of the ignition coil. The positive side is always powered usually...

    The new fused fan fail unit is now ready for sale. I did a bench test with two OEM fans and a static car test in my car with Toby fans. My car is still down waiting for a new clutch so no driving...

    Idle ECU controls the idle motor to hold idle RPM at 775 RPM. It uses the ignition signal to read RPM and a temperature sensor to modify starting position of the idle motor.

    I had to wait till I was 55 years old to get my car. With my daughter working and married and my son in his last year of collage that was when I could afford to get my car. I'm glad I made the move...

    I ran the 40 amp test on the hot side with the new thermal conducting epoxy. To my surprise it ran just about as hot as the T88 epoxy test ran. The new test heat peaked at 90.9 deg. C and the old...

    Ran the test on the new thermal conductive epoxy at 40 amps. As I expected the cold side temp was higher. It peaked at 73.7 deg C where as the old epoxy peaked at 59.8 deg C.

    So I expect the hot...

    I'm still waiting for the new epoxy top to harden so I went back to the old epoxy unit and finished the testing on the cold side.

    At 40 amps, 20 amps each fan the cold side peaked at 59.8 deg. C....

    I poured the top side today with the new epoxy. I found heating the epoxy to 115 deg F made it thin enough to pour. It's still more work than the T88. My testing when it all hardens will convince...

    I got my thermal conductive epoxy today. This epoxy has a filler and is really messy to prepare since you have to mix each jar (the filler settles). It's also much thicker than my T88 epoxy. ...

    It's a good thing to check. Best to use a clamp on DC current meter that you just clip over the jumper wire. Make sure your engine is running.

    I played with one of those when they first came out. It's just a heat pump (much less efficient than a compressor). Takes a lot of current to run it.

    I'm thinking my unit will be fine running...

    I ran the same test with my external sensor attached to the cooler side (away from the power in pin "40 amps"). As expected that side did not heat very fast. The temp stabilized at 59 deg. C in the...

    Heat is mostly produced by the fuses which run 3.38 milliohm cold. As the fuse heats the resistance increases. The wiring to the fuses and the fuse socket also add a little heat as do the "relay"...

    I do remember you have my RPM relay. All versions had the "HOT START FIX". Just pop the case off it an look if the jumper is on the end terminal or moved in one pin.

    iYour hot start issue sitting on the black top on 100 deg day would probably be fixed if you jumper the solid state RPM relay to "HOT START FIX". I had the same problem (three hours sitting and...

    There are different back plates also. The stock DeLorean AC hoses need a special back plate. If your going to make your own hoses than that would not matter.
