No crank no start

Hi Vman,

Welcome to 2 Car Pros,

Can you elaborate on the PCM being bad a little more? What did the computer say specifically when you connected it?

Can you verify that the check engine light comes on when you turn the key on? And when you try to crank it does it go out?

Hey MPNANTO,
I'm not exactly sure what the computer said Because my mechanic was doing the test and just telling me I know he said that there was no communication with the pcm and the faults kept saying powertrain control module and he tried to reset it and it just kept popping up. The check engine light does come on when I put the key in but all the lights come on and when I turn the key all the way everything shuts off and nothing happens at all. When I had the keys reprogrammed to the new pcm the computer was communicating with the new pcm just fine and everything looked good there was no faults at all and the same thing happened when you turn the key all the lights come on but when you turn the key all the way everything shuts off and nothing happens

Sounds like a possible high speed CAN network issue disabling the PCM amongst other modules on this network. To even begin helping with diagnosis on this we would need the code numbers and the modules that they came out of.

How would I get the code numbers? I'm lost I have no idea what else it could be. Someone told me it could be the fuse box but I don't think it's that. When I turn the key I can hear a click by the wires behind the glove box by the fuse box but I don't know I know a little bit about working on cars but not much about electrical.

Hello,

If you can you please shoot a quick video with your phone so we can see what's going on, that would be great. You can upload it here with your response. This video shows how to scan the can for issues.

Have you checked fuse #41 for power in the central junction box behind the kick panel?

If there is no power the computer wont communicate. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
