My son was driving his truck (89 2500 5.7L auto) last night. We were on the phone talking when the engine died like he turned the key off. He drifted off the road safely and put the truck in park. He tried to restart the truck. The engine started, but as soon as he put the truck in drive and pull away, it died. Since then, the engine spins with no issues but will not start. The ignition is giving bight blue spark on all 8 cylinders and the injectors are spraying a beautiful pattern against the throttle plates. It will not even sputter. What has been done to the truck over the last year. A full tune up by me, everything in the ignition system replaced except the module and coil. Distributor is tight and I set the timing by the service manual. Truck has ran flawlessly the last 10,000 to 15,000 miles, until last night. What I suspect are the ignition module, temp sensor, TPS, and oil pressure sensor. These are the things I know will stop a TBI engine from starting and running. I don't have an OBD I scan tool and I can't get one locally, I've tried. No shops are open in our small town or I'd just take it in. It's damned cold here and windy at the moment. Also, can't find any vacuum leaks. This truck has to go to work this evening. All I can do is throw parts at it and hope. Is there anything else I should look into?
