03 Chevy Blazer Crank But no Start

Asked by Aug 13, 2017 at 01:27 AM about the 2003 Chevrolet Blazer 4 Door LS 4WD

Question type: Maintenance & Repair

Hey guys fixing up a 03 4door Blazer for my
mother. Crank but no start. So far I've done plugs
and wires, air filter, fuel filter, repaired fuel lines,
new battery terminals, new battery, new starter,
new ignition control module, new coil pack,
cleaned throttle body, cleaned plenum, blah blah
blah blah blah. Still crank but no start. I have spark
and fuel pressure is also fine. Put a scan tool on it
and got code P1626. Loss of fuel enable signal.
Also security light flashes alot. I know other people
have had this problem and know the fix. Please
help. Much appreciated.
