I'm the guy who asked about the 88 Formula running hot. Now it has
intermittent starting problems after backflusing the radiator and
replacing the radiator hoses.I was able to read a code 54 from the
computer which my Chilton Book describes as "Low voltage to Fuel Pump"
I read elsewhere that it shows that there is less than 2v. to the
I'm thinking fuel pump relay or wet wiring, but I don't know for sure.
The car runs great once you get it started.
The people in this group seem to possess a good deal of expertise so
what's your take on this ? What would you do to fix this ?
Thanks for all of your valuable input.

I would probe the wires entering and exiting the relay. This will
tell you if your getting the right voltage there. Then I would probe the
wires by the fuel tank to check voltage back there if the voltage from
the relay was good.
I could be something like a corroded connector, a wire that has a bad
section, even the relay socket or pins being corroded.
Thanks for your reply. I did check the relay contacts and the plug
also. I didn't see any corrosion but I cleaned everything anyway.
There was a fair amount of moisture in the area around the relay
cluster on the firewall.
I also noticed that if I let the car sit overnight it starts fine. If
I start it in the morning and then restart it again later then I have
a problem. It's almost like something is taking a really long time to
reset itself (the relay ?).
