Ok I've got a '73 Ford F-100 with 390 and a Holley 4bbl and I had the carb rebuilt a few months back. Got the carb back and put it back on and turned the key and it fired right up. Idled high becuase it hadn't been tuned yet. Turned it off and came back to it a month later and nothing. It would not start. Is it possible that the fuel pump went out or bad fuel. I replaced both fuel filters a few days ago.

 

Is there any fuel squirting into the front barrels when you open the throttle?

 

Ya and I pulled the fuel line off the carb and fuel spurted out
