Asked by Apr 11, 2013 at 03:08 AM about the 2002 Pontiac Grand Prix SE

Question type: Maintenance & Repair

I blew a head gasket a while back,
had a trusted mechanic friend
replace it. It started for a second,
then shut off. The security light kept
flashing and simply WOULD NOT
start! He replaced some sensors,
checked over everything 10x over,
ran diagnostics, checked fuses- no
luck! We towed it out to a group of
mechanics who had it for about a
year- working in it when they could..
Disassembled and reassembled all
sorts of stuff and FINALLY found a
pintched ground wire. They DID get it
running, although the security light
remained on, and at this point, it had
sat for so long- who knows what
went bad! They said to drive it and
"clean it out." We drove it a little for a
couple weeks, things were a little
rusty- but working! (Still with security
light) One day, my husband parked it
for about 20min. When he went back
to start it- it wouldn't! We had it
towed, put fuel injector cleaner in the
gas tank: nothing! It sounds like it
wants to start but Won't turn over.
Any suggestions?Also- before the
original problem: I
was experiencing issues with ALL of
the INSIDE lights randomly shutting
off on me! All the outside lights were
still working. Had fuses checked, but
everything seemed fine. The lights
NEVER went out when anyone was
looking at it- mysterious :) didn't
know if it could be related

assure good ground connection from a battery that's newer than five years old to the chassis and to the engine, be sure the positive side has no corrosion as well, with renewed power you problems should magically disappear~

body control module, GM troublesome for 30 years,vats pass key signal generated bypass unit should correct security issues ,no start no injector activate , 35$ override module to eliminate body control security issues,no injector no start. baker electronics is one supplier to note,others also

Try to start it and leave the key on for 10 minutes the security light will shut off and it will start after that
