2001 F150 4.6l triton V8
I have replaced the fuel pump, fuel filter, all 8 injectors
and my F150 will not start. The fuel rail pressure is
within specs. The engine will turn over, but is seems
to drain the battery quickly. It's a new battery. I know
the fuel pump comes on for about 2 seconds before
starting. I am unsure about while cranking. I also
replace 2 of the original coil packs. One of them fell
apart when I removed it, i.e the spring fell out and the
insulation boot fell off. Will a spark tester work with
coil packs? What else should I check? Feeling
frustrated...
