Ok...very informative reply. Thanks.

Hey, I just might take you up on that offer Steve.

OK. Can I jumper the connections to check that? The plugs are new and do not seem to be overly wet when I remove them.

Sitting in the driveway. No high rpm's involved. maybe 2,500 - 3,000 tops. Maybe I should try another ECU. All I see on this vehicle is a Transistor module approx 4 x 5 on the passenger side at the feet. Is that the ECU for this car?

Hello all, I have a 1978 280Z and it will only start after sitting for a few days. After sitting for a couple days It will run until I turn it off, then I cannot start it again until it sits for two more days give or take. I tried another ignition coil. I changed all the spark plugs. Tried a new rotor. It has a newly remanufactured distributor. Sounds like it's flooded maybe? It IS getting a good blue spark It is getting the spark, at the right time (took valve cover off, made sure position of dist in relation to cam lobes on #1) Before the mandatory two day wait after last run, It WILL NOT start if I introduce Starting Fluid into the engine. It will NOT start if I introduce fresh gasoline into the cylinders. (Again, there is a blue spark and I'm sure it is at the right time) Took the plugs out and cranked the motor over, fuel mist comes out as expected. I can hear the fuel pump running and fuel circulating in the fuel lines. However, if I just wait two days without trying to start it...BAM! It starts right up. ONE time. Could possibly be a spark that is too weak to overcome compression suppression? Never seen anything quite like this. It defies the rule that says.... If you give a healthy and properly adjusted motor good fuel, air and adequate ignition all at the correct time, it MUST start....because it has all 3 and still won't. I'm stumped. HELP!!!!!!
