Hey everyone,

I've been going crazy trying to get my Durango started once again. When I go to start it, it just cranks and cranks, but there are no RPMs (either on the tach or from a scanner). The check engine light is not on, so there are no codes to help.

Here's what I've tried:

[ul][*]New Crank Position Sensor (okay, 2 new sensors just in case).[*]New Cam Position Sensor[*]Checked fuel pressure - 45 - 50 psi.[*]Noid light shows the injector firing once when you start to crank.[*]Backprobed the crank sensor and can see that it's giving a signal when cranking (0- 5 volts)[*]Checked that there is 5 volts supplied to the sensors from the PCM when the ignition is on.[*]Checked all the fuses and links - all good. Swapped the links around, just in case.[*]Battery is charged with 12.6 volts.[*]Checked and cleaned all the ground staps.[/ul]
Do you guys have any ideas at all? I can't think of anything else to try!

idk for sure but maybe you could check the coils

 

Yeah, that's the one thing I haven't checked yet. Since there are 8 separate coils, you'd think that enough would be working to get it started at least.

 

You always check for spark and fuel first.

Second, What spark plugs are you running?

Third it might be a relay/fuse.

 

I am with hydra spark plugs andyour coilscan make a difference. I once ran bosch in mine and had the same problem after 400 miles. GO Platinum 4's.[sm=boosign.gif]

 

Does the cluster show no bus????
