electric fuel pump?
i have a question for you i have a 1991 f-150 with the 4.9 inline engine.I had to park it back in february when the transmission let go well i have now replaced the tranny but the truck wont start.i checked and its getting spark but doesnt seem to be getting fuel..when i turn on the key and have it on the front gas tank i can hear the what i believe is the electric fuel pump running but it doesnt shut off unless i turn off the key.I know when i parked the truck it was low on fuel but it was running...is it possable that what was left in the tank for fuel evaporated out and its that empty(i have put in 3 gals of gas b4 trying to start) or do i have further problems?? any ideas or suggestions would be appreciated thanx tim

Elect. Fuel Pump problem
Hi Tim,
I just posted a reply to Bronco Dan's question, and your's sure sounds similar. First thing to do is to make sure you have juice at the tank(s), if so the next thing I would check would be the relay under the hood. There are several things that COULD go wrong but if you have juice and the relay is working, then I would look at the fuel pump, since you will have to drop the tank to get at it (them if you have dual tanks). Chances are you will be able to fix it before you have to drop your tank (I hope)
