I have a 2004 Grand Am V6. When I turn the key to start, it cranks for about a second, then stops cranking. I swaped the starter relay with the fan relay (since they are exactly the same down to the part number on it. ), but it still did the samething. I then used a remote starter to crank the starter directly, and it cranks over like it should. With the key in the "ON" position and the remote starter, I am able to start the car. So, since the starter worked, and the relay didnt fix it, I decided to install a new ignition switch. It still does the same thing, but if I keep trying, it will sometimes crank over and start. Im confused... anyone have this problem before?

I had the same issue .... I took it somewhere and the guy said that the PCM output was weak and could only drive the starter relay low for a few seconds.

I had issues with the security indicator coming on.... so I thought it might be that.
In the end, with the Berger Fix installed correctly => http://www.bergerweb.net/PasslockFix/ the security light is OFF, but the car still cranks for a few seconds.

the guy said, that i could replace the PCM ($500) or wire in a push button directly to the starter relay. I chose that option..which works most of the time.

I'm still wondering whether the computer could just be telling the starter relay output to go off after a couple of seconds..... if that is the case...what are ALL the reasons that the computer would turn off that starter relay after 2 seconds ?

How could I read the voltage off of the PCM? (He supposedly did) Is there a way to read with an OBD2 tester with some software whether the computer is turning on that signal ? Or to activate that signal? If I could activate it I could see if it craps out after 2 seconds.

Thanks for any help !!!

Welcome to the group. Instead of posting to a dead 4 year old thread, you should post a new thread so it's easier for people to help you.

You didnt know. Dont sweat it, just keep an eye on the dates that are posted above the username. That will tell you how old it is. :)

But sometimes its better to create a new thread, versus revive a dead thread.
