So I have my 1987 F150 up the mountains for deer hunting. After the morning hunt I drive up the road (unpaved through rocks and hills) a few miles back to see what other hunters have gotten. Well I went to turn around and going from Reverse to Drive I stalled out, no big deal right? Well it wouldn't start back up. I checked the coil wires they were tight. I sprayed ether into it and it starts and then stalls. So I figure it's not getting fuel, go out and buy a $130 fuel pump and still doesn't fix the problem. I have no computer and no phone service up there and minimal tools. I got a hunter to drive me into town where I made a call and got my brother to drive up 2 hours to get me then back down. Rough Monday-Tuesday...Now I am going to get a 4X4 tomorrow and drive up and pull the truck out of the woods to my cabin (its 2 miles into thick deep PA woods) I walked it twice today. I AM BEAT! Someone please help! The next time I go out there I want it to be my last

 

Hell of a place to break down. And by the way I did jump out the Inertia switch and that wasn't it either

 

the first thing I would check would be the fuel pressure, what pump did you replace?

 

I tried pushing the pin down to see if any gas would spray out and it didn't.

What do you mean by which pump? Its a silver cylinder mounted on the frame
if that helps

 

ok, I believe you changed the in line high pressure pump, did you try turning the key a couple times without starting it to build up pressure? if it still doesnt start it might be the in tank fuel pump, does it have dual tanks?

 

Yes Thats the first thing i did was turn key on/off....it does have dual tanks, but the front one is not hookedup..I disconnected it back in August because there was a leak in it

 

And yes it was the high pressure pump, I didn't realize there was one in the tank

 

Yep, three fuel pumps.

 

So I guess the one in the rear tanks needss to be replaced

 

Definitely maybe.
