No Spark??

My 535 has been sitting for a few months... last week i went out to move it... and there is no spark. Ive got 12V on either side of the coil but it will not fire?

Any Ideas?

Got Bently?

Could be alot of things wrong. Check for fuel, air, and power to the computer. Check your fuses to make sure they are seated correctly.

This happend to me on the weekend.

There are many possible causes, including reference sensors and ECU, but mine was a simple loose connection. There are FI 2 connectors on a brace at the rear of the intakes, one was loose - corroded ends, cracked plastic. Fixed.
