On the bright side the clutch hydraulics seem to be functioning fine so we won't need a clutch slave.
I ran the engine for about 30 minutes today and it suddenly died just as if you had turned the ignition switch. It would crank over but not start until it cooled off. Maybe we can look at it after the July 8th club meeting.

I got the car running today and the miss is gone but it is idling high.
...

If something changed drastically, it may have changed the idle.
It needs to be driven at 30+ MPH to reset the IAC.

I can drive it and it will be covered under my shop insurance policy. I will run it tomorrow and if it dies out I'll see if I've lost spark since the fuel system seems to be in order.

The car was trying to quit and the fuel pump was howling the last time I drove it.  Discovered it was out of gas.  I only put 2 gallons in it, so you might want to make your first trip to the gas station.

Dieing after it builds up heat might be that the ICM is breaking down.  They can rejuvenate after they cool down.  You can still have spark but no fuel pump.  The pump will cycle when the key is turned on because that's a function of the ECM, but there won't be enough fuel to make it run.

Mike told me he has it all back together.  High rpm and no power.  We troubleshot it over the phone and he found a vacuum line on the bottom of the throttlebody had slipped off.  Replaced it and it idled down to a smooth 900 rpm.

I had put 5 more gallons of fuel in it when  I delivered  it to Mike's shop.  That quited the pump.

Wouldn't that make you figure that the pump is bad?

Originally it only had a few gallons in it after the pump install.  I occasionally drove it around the subdivision or started it to keep the engine running and to try to find the skip.  The fuel got so low that the pump wasn't submerged enough.  That's the reason for the howling.

It had suddenly stopped running.  I went down and swapped out the ignition module, but that didn't help.  We also swapped out the pigtail from the coil to the module, but still no spark.  Mike's putting his spare time toward getting the Aerodonamic car up and going in time for Run For The Hills, so this one currently comes in 2nd.

Ah.  Not that I doubt MikeMac's abilities, but I hope RFTH won't be the first excursion with the Aerodonamic car.

I haven't seen MikeMac post for a bit.  Probably busy working.

For the fastback, I hope the timing hasn't slipped.  Have to move up the wiring to check for spark.

Timing wouldn't affect spark.  We believe it may be the pickup coil. 

Mike has to replace the transmission on the Aerodonamic car.  Replacing a locked Isuzu with a Getrag.
