Well I believe I have 2 separate issues but too much info is better than too little
A couple months ago I started noticing a lack of power at heavy acceleration I could not get the engine above 3000 rpm except in park also could not get to go into passing gear (even manualy dropping to 3rd or 2nd) this got better as weather got warmer (felt normal with normal driving attitude)
My fuel pump has made a high pitched whine since I purchased vehicle 23000 miles ago (found that this can sometimes be normal)
Anyway what brings me to you is now the truck will not start I came home for a quick lunch about 15 minutes trying to leave the engine would just turn no start no cough quick troubleshoot found that I could not hear the pump whine
after replacing fuel pump truck started right up I let it run for a couple minutes called it good went to bed
overnight truck fired up in morning, again for a quick trip and again for lunch (about 9 milies driven)
upon my return the truck died in park and have not been able to start since I could not hear or see the fuel pump relay functioning could not hear pump (this one quiet) could hear pump running after jumpering relay pins 87 & 30
(constant 12v at 87 with 12v at pin 85 (relay terminal relay removed))
truck still would not start
I replaced the relay still nothing
I have not yet done the fuel pressure test or checked into my spark
I was wondering if you might have any other ideas before I throw a pressure regulator at it
