Jeep died again
92 4.0 aw4.
fuel pressure issue.
first.
would get 40psi on rail.
go to start.
0 psi.
replaced fuel pump.
when I removed it. was not pumping.
found blocked fuel line.
blew out with air.
now with new pump it starts. but psi drops to 20 upon starting.
then drops to 15.
0 fuel in return line.
does this mean regulator is bad ? or injector leaking ?
