Thanks for the observations.
It's difficult to be working on the electrical inside the cabin and simultaneously, listen for the humming/priming noise at the fuel tank. I'll get me an assistant next time.
One of the times that the fuel pump was mistakenly replaced, it was really a pats problem. I had to remove any metal objects, such as a metal key ring from the key, use only one key to turn the ignition on(no second key dangling on the plastic key ring). Have to have a free transponder system between ignition-antenna switch and the transponder key.
My next trip to the US, I will purchase: Haynes Repair manual, OBDII code scanner/reader(I had one but I can't find it) a Timing light, and couple of fuel filters. In the meantime, the broken truck is blocking my garage.
I'll do some more electrical test, and probably end up changing the fuel pump once again.
