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 |
