The truck wants to crank ...all fuses and relays and fuel pump are in working order ... But the security light will not come on and therefore the truck will not start ... Is there a way to bypass the security system?
Expert:  Gary replied 2 years ago.
there is no way to bypass these security systems the only way around them is to replace the pass lock sensor or the BCM which are the 2 big things to cause security system problembut usually when there is a security system issue the light would blink when cranking it overwill the engine run on starting fluid ?
Customer: replied 2 years ago.
No... It does not
Expert:  Gary replied 2 years ago.
usually when these theft systems are activated the fuel injectors are just shut off and it should start with starting fluiddoes it have spark when cranking it over ?
Customer: replied 2 years ago.
Yes ... It's getting a spark
Expert:  Gary replied 2 years ago.
this engine needs spark and fuel and compression to runis the fuel pressure 60 PSI key ON engine OFF ?is the compression over 125 on all 6 cylinders ?
Customer: replied 2 years ago.
We don't have the equipment to check that ... I'm going to tow the truck to a Chevy dealership
Expert:  Gary replied 2 years ago.
since it will not start on starting fluid that is telling us we either have spark at the wrong time or the compression is low or the spark plugs are gas fouled out
