I have a 2000 dodge durango with a 4.7 V8. I drove it to work the other day and it ran good then when i went out after work it wouldn't start. I had the batt and alt test and they were good. So i replaced the camshaft postion sensor and the crankshaft postion senor and still nothing. Can someone think of any thing else to i should do?

 

What your fuel pressure while cranking?

 

I thought of that and I have checked the fuel rail and all is good. I think it might have something to do with the security system.

 

Look under the hood in the PDC and swap the Auto Shut Down relay with a different one of the same number like the horn. Also check all the main fuses in the dash, especially the automatic door lock fuse.


Also you could try to reset the factory alarm.

 

I already done all of that. i am gettin it towed to the stealership and get them to look at it. if it is an easy part i will do it myself thanks for the advice.

 

Might be your best bet.

 

I am getting my tank back today after pay the stealershipathousand bucks to replace the CTM. The pass door lock short circuted and shorted the CTM, which caused the alarm to mess up.
