Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I' m Chad. Welcome to JustAnswer. I' m reviewing your question now, and I will be post back with your reply ASAP
what is the mileage on it?
have you checked fuel pump pressure ?
so when you start no flashing security light ?
you could have a ignition switch problem(electrical part) if it is springing back and cut off power on fuel pump ?
do you have one or 2 keys ?
is there any prior work that was done that you think could have contributed to this problem ?
Can you check the fuel pump relay , it will be labeled (F/PMP ) in the fuse box under the hood ?
please let me know

I think this will suppress the light from displaying , the past 4 years is this first time this happened .
1- since you mentioned , check the grounds to the injector , stick a test light back probe the injector connector and see if you losing the ground from the pcm when it dies ?
2-we need spark & fuel to stay running , what are losing when it is dying can you check ?
3- what kind of scanner do you have ?
power from ignition switch and ground from computer for injectors connector .
hey how are you
1- injectors you need both , they are supplied by power from switch and ground from pcm ,
if you hook up your test light lead to positive side of battery and back probe the injector connector one of the wires should make test light pulsate while it is running, so hook up ur light and crank and watch the moment it dies are you losing ground or try the other test lead on negative side of cable and check for power , or you are losing power when dying or both .
it should throw a light but if the computer is bad in it , it might not , you can go and see in the scanner under pending codes file if any exist but have not thrown the light yet ( we call them pending faults or codes )
i m online all weekend till 12 pm every night , so just let me know and we can go from there
yes you are correct
if you have 2 test lights hook one on each wire , just an idea
