"PS: are you the Red from club4ag that had his car stolen a few years ago?" Yes indeed. You've got quite some memory, the last theft/attempt was a true theft around 1995. The last attempt was some years later, they literally BENT OUT THE FREAKING WINDOW FRAME because I had the door locks shaved so they couldn't be punched.

"You say it does turn over but dies again... that to me points to another possibility: circuit opening relay going bad. "
Nah. Been there, ran a bypass jumper (pins 1/2) to take the COR out of the circuit completely. And then used a test light on the fuel pump power leads, so I could see from the driver's seat that the fuel pump was getting power, during crank and "on".

I only wish it was the COR! I'd actually removed it, opened it up, confirmed both circuits engage with just a 9v transistor battery (which is a good way to test 12v relays, if they engage at 9, they'll engage firmly at 12) AND I checked the contact arms visually (no pitting or anything) and with a multimeter to make sure. Then rechecked again after re-assembling it, because I've seen Bosch relays where parts are fixed through the case, and shift when the case is closed.

"Run a direct 12V feed to your pump to rule this out, or attach a light to the existing feed and check if the light stays lit after starting. " Done and done as above.

"it pays to know what is NOT the problem, so check out everything you possibly can. " ABSOLUTELY! I assume you've read Sherlock Holmes and know the bit about "once you've eliminated all the...whatever remains, no matter how improbable, must be the problem" or words to that extent?

Or as it is sometimes called, "the relentless applicaiton of logic". There's only so many parts in this system, and one of them is hiding under obscurity. I'm almost mad enough to build a pulse generator out of a 555 timer, and feed the car a fake distributor signal in order to eliminate THAT as a possibility. If I had access to a scope, or a tech with a scope...But as they explained to me, no one has scopes anymore, the OBDC port is all they need. (HA)

Even then...logic says it is nothing under the hood, or else it wouldn't do highway restarts, when the whole engine bay is way much hotter. THAT has to point to something, I just don't know what. Fuel pump? Fuel tank vent system and charcoal filter valving? Some other "startup only" circuit?

There's got to be something that hits this specific problem.

Adding insult to injury, the guys on Top Gear (UK) had the nerve to test a Nissan GTR in that gorgeous blue metallic color. If I had a spare $85k I'd be ready to dump my old ride instead of fixing it.

I couldn't make the first payment on a GTR, but that's OK, given US speed limits I'd be safely in jail and it would be in an impound lot before the first month was up anyway.<VBG>
