Re: Fuel Pump on and off???????????
Did you change the fuel filter? If not, it could be causing your pressure to be low.
It could also be a leaking regulator.
Make sure that your battery is good and fully charged. I know...it sounds dumb, but the 96+ CSFIs are very tempermental. If the battery is weak, it won't have enough power to turn over the engine and provide enough power for the fuel pump to reach the proper pressure. Usually when this is the case...the problem is more noticible in the morning when it's cool. As the temperature rises so does the battery voltage, giving it enough power to start.
Have you checked your fuel pressure? How do you know that it is a fuel related problem?
