6/16/2010 HouseCallAutoHook up a code reader to the diagnostic connector under the dashboard on the driver side. This is the way vehicles are diagnosed. The codes will lead to the repair necessary. The cost of the tool is not that much considering that a shop will bill you a similar amount PLUS parts and labor to fix the problem. There are instructions that come with it and it is easy to do. After you read the code or codes, write them down and repost with the codes and we can tell you what parts to buy to DIY if you are up to it. http://www.autopartswarehouse.com/.../E203030.html
If there are no codes found, let me know that. It probably has a bad crank or cam sensor or it has a bad ignition control module.

6/12/2010 HouseCallAutoI do not recall there being a ground wire. Can you explain where this wire was attached to before you changed the starter.
6/13/2010 justinThats what i am trying to figure out it took me about a week before i could get the starter off because i didnt have the extension to loosen the starter bolts but there is a black wire about the same thickness as the red one that is attacvthed to the solienoid there is also a smaller black wire connected to the solienoid. I looked all around the frame by the starter and couldnt find the hole for it.
