ive got a 94 bmw 318 is that has been a money pit. orginialy the car has been having a hard time starting up. recently the car has had a motor replacement because of a cracked head and still has a hard time starting. i think its just a fuel problem, i was wondering if anyone knows a quick and easy way to trouble shoot the fuel pump, so i can see if that is even the problem. thankyou for your responses in advance
