I have a 1987 ford bronco 2, I have been having fuel problems. I recently changed my relay switch. After that it would cut off on me. I then changed my fuel filter and it still cut off on me. I checked my lines and found a leak in my cartridge fuel filter. I bypassed it buy adding another fuel filter. The car drive for a while, it cut off on me a couple times, but when I added gas it worked. I was driving when the car was going like it was getting no gas, i parked, the car cut off, then it doesn't start....what can b the problem?????
