Quick troubleshoot request please.
 

I have been getting my '90 Cab repainted and it sat around for a bit. Now we are having trouble getting it started. Have replaced the DME Relay and the battery is new. Turns over strong, but no spark.

Anyone have this answer in their back pocket?

ps - already tried searching, but probably not defining my search parameters very well. Could use help on that too:) 'no spark' turns up garbage.

Sure there's fuel?

The old standbys are to disconnect one of the coil wires and see if spark jumps, and crack the fuel feed line where it goes into the fuel rail to see if it's pressurized.

Dear Tagsley

If in fact you don't have spark I would first check that there is 12 volts at the coils.

Thanks guys. Will do and report back. Research is turning up something about a flywheel sensor as well, so trying to learn more about that too.
