HELP! Ok i have a 96' GMC Suburban 5.7. trouble starting. 1)When i turn the key the wants to turn over but it is just flooding. 2) When i turn the key and pump the gas pedal it just flooding. 3)when i turn the key and hold the pedal to the floor(not pumping) it tries to turn but takes est. 10-15 seconds and starts. now once its started i can drive anywhere it seems. But when i turn it off same thing all over again to start it. in last 6months i put a new fuel pump and filter in it. someone said it is a cold cranking problem,but i can go out in the cold and hold the pedal to the floor,turn the key and after 10-15 sec of it trying to turn over it will start. just dont why it wont by just turning the key. 7 Answers

Does the fuel filter cause my truck not to start. I put $15 worth of gas in it because it wouldn't start, and my fuel pump does come on when I turn the key
