Hi Chevelle Fans,
Its summertime almost and I thought I was solid to go this season and we are having fuel issues with our numbers matching stock SS 396.
History: I drove it 2 weeks ago and drove about 40 miles with zero issues. Took it for a "Sunday" drive... nothing fast or racing like. Parked the car in her climate controlled garage and covered it. This week I went to go use it and the motor just cranked over and over with nothing. Checked spark and all good... then pulled fuel line at the carb after attempting to manual mist the carb and not see or hear any fuel... pulled the fuel filter in the stock carb and its dry! No fuel... also:* Poured a 1/4 cup of fuel in the carb and she fired right off.
So then I went to the stock AC Delco fuel pump and pulled it and it appeared to be making the correct sucking and pumping noise as I put it in a vise and exercised it, pulled and inspected the shaft that strikes the fuel pump and it is fully intact and looks appropriate to me. So off to ORiellys and purchased an after market fuel pump... closest unit I could get do to Covid 19 mess. Installed it and the same result... No fuel. I do have fuel from the tank to the fuel pump but as an extra I even blew out the fuel lines to make certain. Re installed the fuel pump again with correct vent line (smaller one) going back to the tank and supply line to the pump. Same result...
What am I missing? Don't tell me the lobe that drives the shaft just went to heck and I need to tear into the motor? I am I installing the fuel pump incorrectly? I did do a series of crank tests with the fuel pump off to see if the position of the push rod changed after a series of cranks and it would appear not.
Help!
