The car will crank fine but when you push the gas it has no accelerator, no power.

Hi,

This can be the result of a few things such as fuel pressure, a plugged catalytic converter, and so on. Is the check engine light staying on when the engine is running or flashing? If it is, then you should scan the computer for diagnostic trouble codes. Here is a quick video showing how it's done:

I realize most people don't own a scanner, but often times a part store will do it for free or lend/rent one to you.

Next, a plugged catalytic converter can cause a major power loss. Take a look through these links:

Here is a link that shows in general how one is replaced:

Next, low fuel pressure can also be an issue. Here is a link that shows how to check fuel pressure:

There are other things as well that can cause power loss, but these are the most common. If you can, let me know about the check engine light as well as if there are any additional symptoms you noticed such as a rattle, hissing sound, or anything you can think of.

I will watch for your reply.

Take care,
Joe
