BE THE FIRST IN THE WORLD TO SOLVE THIS!!
This car is fast, smooth and reliable. Reliable because I learned it and respect her. After 5 hours sitting, she will crank, but no turn over. However, disconnecting the battery for between 30 minutes and over an hour, she will start. Greatly hesistate, but start. After around 12 minutes running she can be cut off and back to normal.
She fires quick when you turn the key and starts nice and smooth. This car runs like a champ. But no one is this world can lift this one burden. I did not go to dealer because I was told they cannot be trusted above all. I have put over 300 dollars into "so-called" solutions, assuming now maybe bad ground. What do you think, or shall you also scratch your head? What I done is below...
Mass Air Flow Senser
Crank Sensor
Oil Pressure switch and change w/Filter
Alternator
Battery
$44 Iradium plugs new (used but good wires)
Air Filter
Just Installed ICM!
I think I think this is all

O fuel pressure is great and so still is spark. However I was told when no start, check it then to confirm pump good or failing. But how can pumps have these intermittent issues that look electronic?

Best way to check it, cheap, is have a can of carb cleaner handy.......
When it won't start, spray into the intake....then attempt to start.....if it starts and runs until the carb cleaner burns up, you know you have a fuel delivery problem...either the injectors are not firing(possible SECURITY problem).......or insufficient fuel pressure......just depressing the schraeder valve and seeing fuel does not mean it'* enough pressure, you need a gauge attached, 40-50 psi.....
If it still doesn't start with the carb cleaner, then you must check for spark.....
Have you scanned for codes?
