Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** can be caused by anything from a bad sensor to the security system acting up. If the security light is on when cranking the engine then it is engaged. If not then it is more than likely a fuel system problem or a failing crank position sensor, which is a common failure. You need to use a computer scan tool to see if there is a crank signal when trying to start it. If not then it needs to be replaced. It can also be an issue with the ignition module or the distributor. Please let me know if you need more help.
