Got a e53 4.4L that just stopped
Replaced fuel filter and fuel pump( symptoms pump couldn't supply enough fuel starved at on 4k rpm)
Getting 60psi at tank
Drove it home 20 k's now
No fuel pressure at motor again
Could it be blocked fuel line or regulator
Does the regulator require vacune to let fuel till the motor
Carnt get access to a hoist till next week to get panel off filter
Is the vac switch on front of block right side?
At Whit's end
