My high volume mechanical fuel pump works great, and there is NO switch to forget.
|
I'm glad you found your problem. I had the same situation happen and it was a bad coil that would shut off whenever it got hot.
|
I run a mechanical fuel pump but I have been thinking about also installing an electrical one so that the carb bowls are completely full before starting, especially when the car has been sitting for a while. I seem to remember thatmany people have had problems with the Holley electrical fuel pumps.
What type of electrical pump is most reliable? Wayne |
Ture007, lack of fuel or extremely low on fuel in the carb causes a lean condition which leads to a backfire on occasion.

Wayne,
I ran a Holly Blue Electric pump on my Cobra for 10 years and never had any problem. I must have gotten the one good one they made from what everyone else says about them. The coupe has an Aeromotive on it. Ron :) |
How did you verify the pump was bad? Only 3-4 psi of pressure will not cause the symptoms you said you had. My own car runs at 3-4 psi on the mechanical pump and 6-7 psi on the electric with no change in how it runs.
Did you ever pull the dist and check the roll pin like I originally suggested? |
You stated at the beginning your pump pressure was fine.
I hope this works for you. :D :D |
Thanks everyone for all the help. Turned out to be the magnetic pick-up in the distributor. Working great now!
|
How did you determine it was the pick-up? Seems funny that it would be intermittent.
Good reason to carry an extra, though, and they're cheap. Thanks, Lowell |
