Well I followed Adny's advice.
The repair noted in the page he sent me had already
been done on my truck, though I found that I did also
have quite a bit of corrosion on the blue-yellow stripe
wire splice that controls the fuel pump relay and the shut down
relay.
I stripped, cleaned, and soldered these these up, but
no avail.
I tried ohming the resistance of the fuel pump circuit
from the relay output to groung and it was reading 12 meg.
I crawleed on the ground, gave the tank a rap or two with
my hand, and ohmed it again. This time it was 5.7 ohms.
I jumped in the truck, started it up and got it into the
garage.
It looks like the fuel pump must be bad or intermittent.
I guess the tank is coming out again.
One thing I negleced to note in the first message was my
truck has 150K miles.
The tough part is a few guys from work suggested to just
replace everything in the tank the first time I had it out.
Oh well, I guess the free advice was worth more than the
cost this time.
Thanks for the reply - Al
