2007 Ram Cummins starter runs for 1-2 seconds after engine starts

Question

I have tried everything I can think of but can't solve this issue. Using chrt5 and install diagram c (I have no +starter wire) all updates are current. The starter stays engaged for too long. I don't want to break my starter or my flex plate. Please help.

Answer 1

Can you confirm for me if the Green/Red in the 20 pin connector is connected to the Purple of the T-harness?

Answer 2

I just inquired into this and:

 

This is normal if you are using the Evo ALL in standalone mode, the slight overcrank was added, after the issue of Ram diesels not cranking enough when COLD in standalone model.

 

if you want this not to happen the only options would be to ADD a separate remote starter to control crank time and turn off standalone option D1

Comments

Is there a older or different firmware I can use that does not have the extended crank time. It is almost exactly 2 seconds too much crank time. Yes, the green/red is connected to purple for the MUX connection.

Can you give us your service number (on the bottom of the evo all unit, 12 digit number) so we can see what firmware you are currently using and recommend one if possible to fix this issue.

You have to use connection C, but will need to connect the Green/Red in the same position listed in on connection F. If I remember correctly, the pin that the purple wire of the T-harness goes to, is either empty or completely something else on the 2007 RAM and any other vehicle that typically uses connection F.

 
Also, turn off the Run Status option in the evo settings. Option E2

Yes Robert I am using connection c with the yellow wires hooked together and the green and red connected to purple. All of this has already been stated, but thanks anyway. It does the same thing with option E2 off it was just the last thing I tried last night.

Yes I know, which is why i was pointing out a mistake.
 

Even though you have to use connection C since you have no start wire, the Green/Red goes to the same position as connection F, not connection C;  In connection F, the Green/Red does not go to the purple wire on the Tharness. It connects to the MUX wire at the ignition switch.

Robert, your highlighted section goes right around a box that says; If you do not have a + start wire use connection C. It does not say pick a few connections off of this page and a few off of connection c.

Another thing, the purple wire of the t harness connects to the MUX wire in my 2007. All of my wiring is correct.

---

So, Jesus Monroy, what you are saying is that this is not going to work properly with my vehicle. Is there anything that can be done about this? I'm assuming that you either work for or with Fortin so would there be a possibility of a specific firmware for me and several others who are having this same problem with this model year pickup? I have seen this question on here and some Web forums with the exact same problem only on the 07's.

The vehicle is overcranking because the ignition may not be being powered correctly.

So, that said, test the ignition wire at the main ignition harness when remote starting. If there is no power there, at least try doing the ignition connection as per connection F. The vehicle ignition circuit may want to be powered from the ignition harness and not the Skim module.

---

That vehicle has been done thousands of times since it came out in 2007 NikBa47, and what Robert is suggesting makes sense, since you are having issues right now, and the only way to figure out what's happening especially in this case where we cannot physically see the vehicle and test wires ourselves is to have the client (you) run the tests for us.

 

What he is suggesting makes sense, if you can test the Ignition wire on the 5 pin connector at the end of the ignition switch on the vehicle (middle pin) we need to see 12v on that wire when you remote start the vehicle.

 

Also Robert telling you to try and hook up the MUX wire is to eliminate the chance that there is no mux wire present on the OEM connector for the immobilizer. connecting it at the IGNITION switch eliminates this possibility.

Doing connection F will eliminate possible missing wires, just disregard the starter connection since you do not have this wire in your vehicle. The MUX wire connection is very important in your vehicle because that is the wire that sends the signals (varying voltages) to turn on ACC, CRANK, etc...

Alright then I guess I will have to make a video and post it to YouTube for you guys.

Ok guys here we go. On the end of the ignition is a 6 pin connector not a 5 pin. Within that 6 pin connector is: Pin 1-Ground, pin 2-Mux, pin 3-ignition 12v, pin 4-empty, pin 5-empty, pin 6-12v B+.

I wired this thing up using the w2w method guide 5061 ommiting the connection to pin D6 because I don't have + Starter wire. Still same thing.

I then wired up using guide 5051 Still with the exact same results.

Here are my current connections. These pin outs are from my factory service manual and they match the wiring in my vehicle.

Hey nick, at the moment i think your best solution for remote start would be to use a regular remote starter system along with the evo-all, and not use the evo-all as a stand alone remote starter. There's no way we will be able to find a 2007 ram locally any time soon to run some tests on (it would also have to be a ram that has an overcrank issue...it can actually be any vehicle from that generation). I'd love to just give you a beta firmware to test out but we need a car/truck for that.

 

You would still be able to remote start your vehicle with 3x lock since most remote starters have either an external trigger (physical connection), or can allow the EVO to communicate with it the 3x lock. Or, just go for regular aftermarket remotes, range is much better then what oem can ever offer.

 

Any low current or high current remote starter will do the trick. Cranking will then be controlled directly by the remote starter and not the evo-all.
