We have restored a car that sat for 12 years.
We have replaced the entire fuel system, pump and everything at the tank, distributor, lines, all fuel accessories, etc.
(we also did the brakes, all hydrolics, cooling system, all rubber, fluids, etc)
So the car was running.
When I took it on the first test drive it was bogging down when I tried to get some speed.
It would buck like a horse and gurggle.
Then it died all of a sudden and seemed to have lost all electrical power for a few seconds.
I couldn't get it to start after that.
I thought it might be low on fuel so I put 5 gallons of premium in it.
After trying to get the car to run we checked the obvious stuff starting with the fuel pump and found that despite the battery being charged (13v)
we were only getting about 9v at the pump.
After some research on the subject, we added a ground wire to the harness but it did not help.
So my question is this:
Where does the fuel pump get it's power from?
Does the pump get full voltage all the time or does another device vary the voltage depending on condition?
We need to trace back all the points where the power is fed and find where the resistance is.
Thanks!!!
