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.
 
sounds like your sucking air or the pump took a dump new don't mean nothing anymore .
 
electric pump or mechanical?
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
 
Broken diaphragm? Had this exact same issue last year.

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.
 
I guess I need to finalize this thread. It turned out to be the eccentric wheel broke the tip of the key and was spinning free. The key had a slight nick or ding on the corner when I installed it but I didn't think it would become an issue. I guess at 6400 RPM you will always find the weak link.
