truck wont start no mater how hard i push the clutch in. i pulled the code p1670 with a superchip had held programmer. i read that it could either be the IDM or the CPS where should i start? i need this truck back up and running asap.

it aslo threw a cam sensor code with it. please help guys

 

Communication error between PCM and IDM. Check your fuses. I think the IDM relay is one of the relays on the fuse panel. If so try swapping the IDM relay with the accessory relay.

 

So they are the same type of relay? I just take the accessory one and use it for the IDM?

 

Yes. All the relays on the fuse panel the same.

 

What does the accessory relay control? Could I steal that and use it so I can drive the truck till I get one if that's the problem?

 

The accessory relay controls the power windows and radio and things like that. Yea, you can drive the truck with out it.

 

Ok can I get the relay at like a napa?

 

I'm pretty sure you have to get the relays from the dealership. They're about $13 I think?

 

Ok sounds good. Thanks for the help guys

 

Now what guys? Tried changing the relay out with another one and still nothing!. I'm completely stumped right now.

 

I can bump start it and it will run just fine.

 

Please explain.

Atleast that rules out any IDM issues.

 

My drive way is a hill if I role down it and drop the clutch in second it will start. Would that be the clutch sensor?

 

Can you clarify the problem a little better? Is it that it won't crank at all with the key, or will it crank but not start and run?

 

You can try swapping the starter relay
