My vehicle listed above is FWD. The engine randomly has issues turning over. I try starting it and it will crank but not turn over. I stop, wait a few seconds, and try again and it will crank and turn over. This happens 50% of the time randomly. I have a new alternator, new battery, new starter and recently replace the fuel relay trying to figure out the problem. Any idea what the issue could be?

Hi,

Just so I am clear, when you turn the key to start and it does this, you said it cranks but does not turn over. What do you mean when you say it cranks? Normally cranking means the starter is turning the engine over is trying to start.

Maybe getting a video would help just so we are on the same page. However, here is the wiring diagram. We need to suspect the ignition switch or depending on what it is doing it could be the transmission range sensor.
