Car will not move forward gear 1?

Hi,

Is the transmission an automatic or manual? Also, when you say it won't rev, what is happening? If you have the vehicle in neutral, can you rev the engine?

If you haven't already, I recommend scanning the can-bus to see what codes are stored. CAN stands or controller area network.

Basically, the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them. This is where I recommend starting. It should point us in the right direction.

Here is a link showing how it's done:

Let me know as much as you can. If you have already scanned it, let me know what codes are stored.

Take care,

Joe
