    Ok... So I got the car to start on about the 3rd time cranking it today. Drove it up the road a few miles & came back. Ran perfectly normal, no CELs. Pulled into the garage & shut it off. Won't restart. This is maddening... Before I tried to start it I checked resistance on all the injectors, they were all between .012-.014 ohms. Put 12V to each injector to see if they're firing, yep. So, we're back to no injector pulses other than the prime cycle. I can't even just crank & crank because it fires enough every time to kick the starter out.

    Yes, I've swapped relays around too.

    When you drove it was it long enough for the temp to come up to operating temperature? I just fixed a problem with my 00 GTP where it was hard to start when cold or wouldn't want to start at all without pushing on the throttle, wouldn't do it once it was at operating temperature. It was the Idle Air Control Valve. IAC. Swapped it with a spare I had and firing up on first crank like normal. Just a thought.
