Help! Fuel Pump

[Rob82]

Hi have a 82 crossfire and I am have problems with the fuel pump. When I hook up the battery charger and put it on start boost the fuel pump will work and the car will run for a few hrs then when I shut it off and try starting the fuel pump will not come on until I hook the battery charger and set it to boost I already changed the fuel pump relay and that is not it I have a fuel pump ac delco that I will be putting in this weekend is there something I am missing as to why it will start only with the battery charger....

Hi Rob (?), welcome to the CAC!

What model fuel pump do you have? The original or did you go 84/85 yet?

When mine failed, the car even ran, but wouldn't take well to trying to accelerate at all; anything over 1500RPMs would make it die.

If it's still the original, i would swap it out for the newer style.

Are your connections onto your battery tight?
If they're not you will be getting a drop in voltage across these connections; which could affect a motors performance.

I just have a new AC Delco fuel pump that I will put in this weekend I am going to check all the grounds too... I heard that I can upgrade to a 85 fuel pump...

Yes they are tight I also put on new cables too but I will check all and see if they are all tight.... I will be working on it this weekend and see if I can get it to go..
