That is normal. When in RUN, the PCM primes the pump for just a couple of seconds and switches off the relay until you turn the key to START and stays running. Instead on a meter, use something that draws some amps, like a headlight bulb, to see if enough amps go through the wiring. It can happen that you can see a no load voltage but drops off with an actual load. When plugged in, do you hear the pump run while it's priming?
That's pretty low voltage while cranking. Is the battery good?
The battery has been sitting for a looong time. So it's a little weak. I'll get it onto a charger tonight. The pump is out of the tank and in a different room but back when it was installed yes, I could hear it prime.
If there's low amps under load, what's the busted component?
Looking at the Bosch paper work now, and wondering how to get a refund from Amazon. I want a better pump. Called Newparts Inc. of Gordonsville, TN (the seller) and left a voicemail. Was told to expect an email reply.
Load testing completed. I am reading 0.1v negative side and 0.3v positive side. So no problems are obvious. I'm thinking next; get the pump installed and hook up the tank. I'll repeat the load test with the tank connected, but not strapped up.
Amazing, isn't it. Back in the day, GM had a problem with distributor caps. They were scrapping defective ones, but they kept turning up, then were returned to the store again.
Turns out someone was pulling the caps out of the trash and re selling them.
