A little confusing since you said it won't crank...
I'm assuming it will crank but won't start.
That being the case, sounds like you are losing residual fuel pressure.
Put a gauge on the fuel system and verify.
Some(most) EFI pumps have a check valve built in to maintain rest pressure.
You didn't mention changing the pump, so this could be the problem.

All,
Well, I need some more help. I thought I had the problem solved, but it
seems I don't. If I keep replacing items, I may soon have a new bus!
The problem is that the van will not start for about 45 minutes after it
reaches running temperature and I turn it off. It runs great while it is
running. Cold start is not a problem. No problems at all. If I drive
about 20 miles and go in a store, when I return it won't crank. If I wait
for another 45 minutes or so it cranks. Drive a few miles, turn it off to
go in another store, and the same thing happens again. The engine turns
over, but no cylinders fire.
I have done the following
1. Replaced the ignition switch
2. Replaced the coil
3. Replaced the fuel pressure regulator
4. Replaced the idle module
5. Replaced the air valve
6. Replaced the injectors
7. Cleaned all ground connectors, those on the motor and the bonding cable
between the frame and the transmission. The van has never been to the beach
or run on salted roads. No corrosion any place.
8. Replaced the temperature sensor.
9. Replaced the wire from the computer to the temperature sensor.
Tomorrow I am going to see if I can find some liquid air and try cooling
down some connectors to see if that may be a problem. I think that the last
time this happened it was getting fire. I will check again to be certain.
Any suggestions will be appreciated. I'm getting too old to keep this up
much longer.
George
84, Georgia
