QuestionThe gas is not being pulled from the tank to the fuel pump. I have blown the fuel line from the fuel pump back to the gas tank and it appears to be clear and the fuel pump has been replaced.
AnswerI'll have to guess which engine your car has, but the first thing that comes to mind is a problem with the push rod or cam lobe (depending on which engine you have) that operates the fuel pump.
Did you notice a "springy feeling" pushing on the lever as you installed the pump? If so that is OK, but if not, something isn't right with the installation.
Take the fuel pump back off and look in the hole - do you see the push rod or cam lobe that actuates the pump lever? Did you push the rod back up out of the way when you installed the replacement pump, or did you somehow miss the cam lobe, so that the pump is not being operated?
The other possibility is a problem in the fuel line somewhere - such that you can blow air back through it, but when you try to suction fuel from the front, you get air instead of fuel due to a pinhole somewhere in the fuel line on the suction side.
Still another thought: When you blew back into the tank, did you hear bubbles in the tank? If not, maybe your gas level is too low, or the pickup tube has fallen off inside the tank.
This should be an easy one - you'll just have to do some detective work. Of course it is always possible that the "new" pump is defective, too. You can put in a vice and operate the lever by hand - you should feel a strong vacuum if you block the inlet fitting with your thumb, and you should feel pressure against your thumb on the outlet side.
Is there any chance the in and out are reversed on the hookup to the pump lines?
OK, I'm out of ideas here. Go forth and figure it out!
Let me know, please.
