i have a boosted hatch with 450cc injectors. every now and then when i try to turn on my car the fuel pump doesnt come on so the car will just crank. so we have to put the key in and out waiting for the fuel pump to come on, and we know it comes on when my AVCR screen comes on. whats going on? has the fuel pump gone bad?
