Alright so here is the dirty...got the 4.6 and it started havin delays in starting it progressed to now the point it wont fire just sits and cranks...I have not had any rough idling dramatic acceleration delys or misfires...started off with fuel pressure kinda crappy so boom new filter still not what I wanted boom fuel pump/sending unit...hoping that would solve the not starting issue and the pressure issue all together...NO! so for ****es and giggles pulled every fuse/relay and reseated them nothing...it will turn over and run for however long I spray fluid in the intake....I'M STUMPED ON NARROWING IT DOWN ANYMORE!!!!
