The solenoid has been cleaned.

I'm sure the map/tps is correct but I will double check. It was doing this before I tore it all down as well, just woulnt run, where as now it clears out and runs.

The factory tach works, the aftermarket one shows movement while cranking and nothing while running.

Can I temporarily ground the it with thick amp wire? Like a wire from the head to the battery just to test?

Also no check engine light. Would autozone be able to pull the code?
