i have a 92 f15o 5.8 it starts then shuts off if i pump the peddle it stays running tried fuel pumps , filter , module tpi, cts, air valve, checked timing, im lost . can anybody help.
Maybe get a fuel pressure gauge on there and see just what is going on
i did that im getting 40 pounds key on and running
OK that sounds about right for idle, I don't have specs in front of me, so I'll assume you've checked that is the correct spec. It should be higher with key on, engine off (KOEO), then drop some when engine running at idle. There are a couple other things you can check on fuel pressure - 1) pull vacuum line to regulator and plug it, pressure should climb about 5 psi. 2) Turn engine off and watch fuel pressure, it should remain constant for about a minute before falling.
