    Thursday night I was at the track and just finished a run and I was heading back to the pit area when the car stumbled and died. It re-fired and died again. I had another racer look into the carb while I cranked and there was no fuel. So I disconnected the fuel line running from the pump to the carb and it was dry. I figured it was the fuel pump and I ended up towing the car home and went out the next morning and it fired up then died again and would not re-fire. I pulled the line from the pump again and it was dry. I took the line and aimed it at the ground and cranked the car and I got nothing to come out. Pulled the line from the tank to the fuel pump and it's full. I took the pump off and took it apart and everything looks fine in it. Like I said it's almost new. I blew the fuel line from the tank out thinking it may have crud in it and blew out all the vents inside the pump re-installed everything and It still won't fire. I pulled the fuel line again from the pump and it's bone dry.

    Specs,
    Almost full tank.
    Edelbrock fuel pump. 1 year old but less than 500 miles on it.
    Edelbrock 1406 carb that has run perfectly for 2 years.
    LA 360


    Before I buy a new fuel pump I'm wondering if you good folks have any ideas.

      Yeah, but before I dropped $150 I thought I'd see if I was missing something.

      Mechanical. I pulled the fuel line from the tank side and stuck a short piece of fuel line in a gas can and still got nothing, I'm reasonably certain the pump is bad so I ordered a new one. If that doesn't do it I'll pull the timing cover and see what's up, but I don't hear anything weird in there when cranking so I think it's ok in there.

      What happens when you pull the cap off the tank?

      I've had a short piece of fuel line, that connects the pickup to the hardline collapse as well

      with the pump off you should be able to look into the eccentric / timing chain area with the right light and mirrors OR an endoscope.
