Q: Turns over but wont start

asked by on

Why will my truck turn over but dont fire
My car has an automatic transmission.

There can be a few different possible causes of no start.

The fuel pump may not be pumping fuel (Have to check fuel pressure).

The ignition is not sparking to spark plugs (Check coil for spark and signal from ignition module).

No injector pulse can be due to no signal from the ignition module.

Have some basic checks to isolate the system to diagnose and go from there. If you would like, a certified technician from YourMechanic can come to your home or office to definitively diagnose your vehicles inability to turn-over issue.
