You said you had the car running well for sometime and then suddenly, a few months ago, it wouldn't start. Is this before you started the frame off restoration, or after you had begun putting the car back together?

If the car has not run well since before the restoration, I would suggest going back through your connections, one by one, and confirming not only that the routing is correct, but that each connection point is clean and secure.

If the car was running well after you had things put back together and then suddenly wasn't able to start, I would be trying to figure out what exactly you were doing on the car right after it last ran well. Perhaps you have notes or a log you keep of your progress or maybe just some pictures that'll help you figure it out. If it wasn't a specific part that you were working on at either installing or replacing, then it might have been something nearby you bumped loose while in there.

I would try and figure out a better timeline of when the problem started and what exactly changed at that point. Then focus your efforts looking there.

It has been running after the frame off. I have basically just been assembling side stripes and rub strips. I had a problem with high beam fuse being blown. The thing I did just before it would not start was to check relays and fuses... I have checked them again, cant find anything wrong.

Did you solve the high beam fuse problem? What was the solution?

Is your battery in good shape and fully charged?

Would you be able to post some photos of those fuses and relays you checked? Perhaps someone on here might be able to spot something you're overlooking?

No not really, did not get to check it since it does not start. I tried switching high beam and low beam realys to see if one was bad. Still blew fuses. Relays are "new" never been used. Bought them back in 2007. And had them stored in a bag inside the house. Car started after this. Changed fuses, since it has been upgraded from sealed beam, someone said there could be more load on the fuses. Also read on deloreango that they recomended putting in larger fuses because of this. Car would not start before I changed fuses...

According to manual if voltage between terminal 1 on coil and ground shows less than 0,5V there is a short circuit in ECU module. Mine shows 4,5V.... (Battery Voltage over 12V)

If you have over 11 volts on the battery and less than 6 on the coil terminal that would indicate a bad coil. Check the resistance of the primary of the coil. It should be between 0.95-1.4 ohms. If you are using a "performance" coil, they do not seem to live long in a Delorean. Get a stock coil.

I just bought the coil from Deloreango, a Bosch coil. Car would not start before replacing as well. I have measured the coil. All seems good

Ok, let me try and get this straight:

1.) Frame off restoration nearing completion and car has been running well.
2.) As you are checking through the systems, you try the upgraded headlights and they blow the fuses (original fuses I see as being 20 Amp in fuse box spots 14 and 15).
3.) You swapped relays (never used spare ones you bought back in 2007) for the low and high beams (and assumingly put regular sized replacement fuses in for the ones that blew?).
4.) While the relay swapping test did not fix the headlight problem, the car itself would still start.
5.) You changed the headlight fuses to a larger type (how large, by the way?) but this has yet to be tested since the car now will not start.

Is this sequence correct?

What I am unclear about is what happened between steps 4 and 5 because from what you wrote, the car would still start after the relay swapping but then you say the car would not start before you changed fuses. It seems like there is something missing between those two steps?

Sequence is correct.

As far as I remember the car started after swapping relays. Then it stood for a few days and would not start again.

25 for low beam, 30 for high beam.

You said, you replaced the ignition resistor. Have you gone back and checked all the terminal connections on it. Oxidation within the female spade receptacles can still cause a high resistive poor connection.

I will check properly!

Also confirm you have good connections of the coil wire at the Cap. I inadvertently knocked mine off the cap once when sticking my hand between the engine and back wall for something else I was working on.

I assume your are smelling raw fuel after cranking attempts, this would at least confirm the FP is running and it is an ignition issue.
