Toggle switch to the fuel pump relay in PDC would disable it for sure you could crank you brains out but it won't run...

Not yet that I know of... But Ford and Chevy's do...

Sad thing is the FSM here is corrupt so I can't see it...

Man I'm truely sorry for you loss... Yea... It time to do a bit of hunting...

After digging through the books and wiring diagrams there in no fuel pump relay in a 2005 Cummins. The lift pump is directly controlled byt the ECM and the FCA is directly controlled by the ECM. As a matter of fact the only 2 relay even listed for a Common rail is the 2 for the grid heaters that's it...

Talk to CajFlynn he's had a exhaust brake on his 01 with automatic trans but the last I knew it wore out... He can tell you... As for me I'm still running around on the factory brake pads from the dealer when I bought my truck brand new in 2002. NEVER done a brake pad replacement yet. I've serviced the calipers twice now but continue to re-use the old pads. Exhaust brake are well worth it and save your rotors and pads considerably.

Yeah typically they hiss out the tailpipe...

Got you covered... http://mopar.mopar1973man.com/personal/2002/bhaf/bhaf.htm Then a good source for them... http://www.vulcanperformance.com/Big-Honkin-Air-Filter-BHAF-p/bhaf.htm

Hopfully you tested the red wire (ECM trigger) to ground? It's possible the valve was jammed partial close... As for the exhaust brake it shouldn't be making a sucking sound the diaphragm unit might be damaged.

To keep this from getting lost I'm making a write up page for it. http://mopar.mopar1973man.com/cummins/2ndgen24v/high-idle-diag/high-idle-diagnostics.htm

Payette, ID yesterday was $4.259... Still hovering at around $4.509 near home...

Well you could just put a pull knob switch on the stick and pull it out when every you want it... It be up to you to use your head and remember to let go of throttle before pulling the knob. Running the truck with the exhaust brake on will cause extremely high EGT's and extremely low power...

Spray the top of the water with WD-40 and the bug problem is delt with because as they hatch they are coated in oil and die.

Well I know the solenoid could be purchased at a Dodge dealer yet.

Great minds think alike... That was my parting conversation last night was use like a reed switch and place by the throttle arm so when the throttle is at a idle the exhaust brake would be set automatically. This would omit the ECM control. Now my problem is Jacob's Brake web site has now dump all their PDF documents on the Cummins exhaust brakes and can't seem to find a wiring diagram of it now... :banghead: I'm guessing the red lead to the ECM is going to be grounded to set the exhaust brake?

Ok... The P0122 code is from our testing last night so dis-regard the P0122 code because when you doing the voltage test with the APPS unplugged it trip that code. (Summary) Since we know the exhaust brake it triggered by a idle state of the APPS sensor it tells the ECM that the APPS is in idle state by grounding Pin 1 on the ECM this sets a timer in the ECM for about 3 seconds and then ground the pin for the exhaust brake causing it to enable. Cumminapart seems to have power and good connection on the exhaust brake wire but getting no trigger. His APPS is stock and the tag is .505 and measured a voltage of .3xx last night so it should show idle state ground. So where we stop was think of figuring out a way to trigger the exhaust brake without the ECM lead (Red Wire).

Southbend Con OFE and use my truck like a Cummins Skidder...

Thing is lets be honest and real here a second... Most people today don't have deep pockets to keep replacing parts on there truck so when someone comes up with a way to re-condition a part with a few O-rings and keep the price down... You just earned a spot on the HTML pages with your write up...

One of the new boxes has a connection to the OBDII port and picks up the Oil pressure and Boost pressure correctly... So yes SGII most likely could if we had the proper PID code for it.

Also like the oil pressure is known by the ECM but SG II can't see it either... I know what you mean...

Yeah there is a few wiring mods for extra grounds and filter to being added to the PCM. As for experience with it sorry but no I'm a manual truck which it never seems to bother them. But the filter can be purchase at most vendors on the internet.

Thank you for the wonderful write up and it will get converted to the static pages... Once again Thank you!
