2000 Chevy Suburban will not start no fuel at fuel rail, fu
changed fuel pump and filter
replaced old style sender unit as per recall
to new style i have checked fuel pump relay
and all fuses are good
Answer
Check the fuel pressure and comeback with the readings-fuel pump might not be producing fuel pressure that will cause the fuel rail not to have fuel-
Good morning
thank you for your help.
yes we checked the fuel press, nothing at the
schrader valve. I now dropped the tank again
and checked voltage at the connectors, pump
and sender unit both have 0 volts. removed the top
half of the fuel/relay box and checked connections
and for signs of coarosion all look good. I did see
next to the fuel pump relay a small recpt marked
Prime. will the aid in trouble shooting. next
I will pull the relay and run batt voltage through
the grey wire and check voltage at the pump
connector so I can rule out a damaged or burned
wire. I have questions re: the security system
is it possible that I am in some type of anti theft mode dissabling the fuel pump.
thank you again for your help.
If you have any idea what I should check next
please reply
thank you Lori

Could be the ATD device
Have you check the ECM B fuse 20amp-see below
