Also tried swapping computers - both work in the running truck, neither work in the non-running truck. I read the codes; 116, 565, and 636. One is evap. Solenoid, I verified that it opens the vacuum line when ign is in, another is engine coolant temp sensor out of range, the sensor is brand new. Won't it be out of range until the truck is running? Third is trans. Temp. Sensor, since trans was also rebuilt, there is probably no fluid contact yet, since trans has not been completely filled? Is there a way to check these sensors w/ a volt/ohmmeter? The connections at the coil show battery voltage on the right connector with ign. On, while cranking, left connector shows 3 volts less than battery voltage. Coil has also been replaced, as terminal tip was broken. I've checked wiring & connectiors, no visible problems or corrosion. I've replaced fuses and the relay. I'm stumped!
