1998 Chevy Silvarado, Code P1351

I have a 1998 Chevy Silverado and it is not starting. I hooked up the computer to it, the code reads p1351 Manufacturer controlled ignition or misfire, could you tell me what this means?

Steve Says,

Thanks for asking me your question. This code is set when the computer sees too high of voltage in part of your ignition system.

The most likely cause of your problem is a bad ignition coil. When the coil goes bad it causes incorrect voltage in the ignition system and the computer sees this and sets the code.

Other things that could cause this problem consist mostly of wiring problems. Rubbed through wires, bad connections, faulty connectors, etc.

I hope this has helped. Please post the fix when you know what it is.
