1995 Starting problems
Car started great when I left for work this morning. Meet the wife for a little breakfast. When I went to leave the car was hard to start. It turned over fast but wouldn't start. Kept fooling with it a few minutes and it started. Once started it runs great. Did the same thing when leaving work and still not starting like it should. Any idea where to start? Seems to be a fuel issue?

First check just to make sure there is no fuel in the vacuum line for the fuel pressure regulator. If wet, that's your problem.
Then if you can (and better at home) determine if there is any spark. If not, the ICM might be temperature sensitive and acting up when hot. If you end up at the ICM, hard to test for this symptom and replacement is best way to make sure. Easy to replace and would not rip the opti out at this time and jump the gun.

Just as a possible guess, if the check valve in the fuel pump went bad it could cause this symptom.
If the 2 second prime does not hold the fuel pressure, then when you turn it over and oil pressure is built up, it will close the switch for the fuel pump and the pump will come on. Then with fuel pressure the engine will start.
If the fuel pressure does not hold during the 2 second prime for a normal period of time, this could be a problem.

Just got back from B-I-L's shop. Looking more and more like the Opti. Has great fuel pressure, he had a new ICM and coil. By the time the tow truck got it there it wouldn't even crank. He'll start disassembly Monday.
