Hi there,

You need to scan the ECM for codes first.

Can you check for spark?


Customer: replied 1 year ago.
How do I do that?
Expert:  Gary replied 1 year ago.

Can you remove two plug leads from one coil, and get a friend to crank the engine.

Spark should jump between the coil towers.

My bet is you have a faulty crankshaft sensor.

I hope my advice has been of assistance to you.
