So I just installed a new electronic fuel pump. All lines got drained when I took the old one off. How do you go about primeing those lines with fuel. I can crank it with starting fluid but there is no gas getting to the injectors and it will eventually shut down. Is there a trick to it?....Thanks in advance.

I did the same thing recently and mounted my pump to the firewall.
In my haste I hooked-up the pump incorrectly so when I cycled the pump through the ignition it was actually running backwards. Obviously running backward will not suck any fuel. Once I corrected the wiring and turned the ignition the pump immediately sucked fuel and pressurized the system. The car started on the next turn.

Investing in a pressure gauge to add to the fuel rail is worth the money to trouble shoot the system too.

Make sure your pump is hooked-up correctly.....they will run backwards too....

I will confirm that today.

Thank all of you for all the advice. That's what makes this forum the best out there....... (IMG:style_emoticons/default/beerchug.gif)
