Hi,
I had to replace a small section of flexible fuel line back by the engine. About 8" worth. Everything went well. I disconnected the fuel line, the fuel ran out, and I replaced the old line with new.
But when I turned on the ignition the fuel pump doesn't come on briefly and the car won't start.
The fuel pump has been moved to the front of the car so there's no wires to worry about back there.
Does the fuel lines have to be primed or something like that if they get drained? Yes I did put about a gallon of gas back in the gas tank.
Thanks!

If the fuel pump is not pumping for ~1.5 seconds when you turn on ignition then you must have upset some electrical connection. Check all your connections again at the relay board to include fuses and relays. You may have also inadvertently grounded the AAR lead or done something similar. Your problem is electrical.
AFAIK you don't need to prime the pump.

I had to climb under the car in the front, to get to the fuel pump. It was getting 12volts so I did the old wrap on it with the handle side of a screwdriver. It worked! Thanks for sending those positives waves my way!

This is what I had to do to my fuel pump once. Unfortunately, it died within a couple weeks. Hope for the best, but when you have to start whacking the side of your fuel pump to get it to work, it means it will be headed towards failure soon.
