fuel pumps buzz way to long, and will not start, until pumps stop! done the filter, changed pumps, done the dual function reseroir, than done bypass on the reseroir! (problem, the year 1988.)

Hi,
did you find out why your F150 wasn't starting? Was it related to the buzzing fuel pumps?
thx
The ECU in the driver kick panel is the problem. If you take it out and open it up you'll see a blue capacitor has gone bad and may be hanging by only 1 leg. It is rated at 47 mfd and 16V. You can replace it with one from Radio Shack as we did yesterday. Now pump runs about 5 seconds and the truck starts right up. The computer will not give a SPOUT signal(spark out) until the pump turns off.
I have a 1993 thats doing the same thing Iv spent a lot of money trying to fix it still doing it If you find out please let me know [Iv took it to shops they say I just dont know]
fuel pressure is 50 Iv changed the regulator Im showing a 213 code which means loss of spark Im ckecking that out now
