Greetings and Welcome to Just answer.
I will do my best to assist you. When you are finished please click on accept only if you are satisfied. I don't get paid unless you do.Please do not accept if you cannot leave positive feedback. I don't know if you are a tech or a just working on your own vehicle so we may have to fine tune the answer. I only know as much about your problem as you have told me in your post, so my answers will be based on what you tell me so please add all the details you can.
So if you turn the key to start, the engine cranks but will not start, and jumping the starter will make it start?
O, not starting with the key in run and jumping the starter is likely the theft system. IS the light flashing? This has the black pellet in the key?
This is a different style theft system. Do you want to eliminate it? It is likely the cause.
The good news is the bypass is 200 or less. Use this link and if this is not the problem, you can return it in 15 days. Using a different link to the site does not have the same policy as I have an agreement with the owner.
It should be on, but the module may be bad and that will cause the light not to go on. This bypass module eliminates the need for the theft module in your car.
Not easliy and even if you do, it may cost more than the bypass. IF you order the bypass through the link I posted and that is not the issue, you ahve 15 days from the day you get it to send it back for a refund. So this is risk free diagnosis or atleast elimiante the module, but my money is on the module.
