I have a fully charged battery but no spark. Battery does turn motor. Oh I should tell you guys nothing was done to the car. I drove home last night everythings fine tried to start it today and nothing, Checked for spark,none.

 

Are you using the same key? It could be an immobilizer problem.

 

I tried other keys.

 

When you say "no spark", does that mean you've tested for spark at the plugs?
If there's really no spark and the engine cranks, then it sure sounds like an immobilizer or ECU problem. Less likely, but still possible, are other electrical problems like intermittent connections or grounding issues.

If you don't already have a volt meter, now is a good opportunity to get one. Radio Shack, Northern Tool, Home Depot, and many others have DVMs for about $10. It will be an invaluable diagnostic tool in sorting out electrical problems.

 

Yes I checked the sperk plugs.

 

Key light blinks doe that mean the immobilizer?

 

It should blink, then stop with the key on.

 

It keeps blinking with the key on.

 

In case anyone wants to know, it was a module for the alarm. The alarm ia a viper 5902 with remote start.
