haven't checked security system yet, but this has come about as to why truck fires, but dies right away. injector test light only flashes 2 times while cranking, engine dies right away, and when I put code reader on, under test monitors the 07 monitor says STS failed. What does that mean? The owner has never used the security system, can it be bypassed?
Hello. I would need to know more information about the vehicle in order to give accurate information. Depending on the year, make and model of the vehicle I would be able to determine what may be going on. It is also important to get the power train codes from the computer.
