You just need to convince the PCM that you aren't stealing the truck. So, need to disarm the security system. Usually, unlocking one of the doors with the key (twice??) will do it.

Run your VIN thru the equipment listing on Dodges website. See if your truck originally came with the secure key. (grey key. normal keys are black.)

 

The alarms disabled. The headlights are no longer flashing and the horn isn’t honking anymore

 

It says no records found

 

For a 99??? That's odd..... It even pulls up my 96.....

 

This is the tag on the drivers side with the vin. I have a friend who has a friend that is supposedly able to flash the PCM. We will see. Before I let him go messing with the electrical on my truck what should I check first before he gets here?i don’t have a clue what my next step is. Thanks

 

Well, according to the build sheet, (it seems it is case sensitive....) you have remote keyless entry, but, I am not seeing anything about a security system.... Of course, I don't know if it is specifically mentioned or not.....

8 Liter? D70 rear? OOooooo. Nice.

Dealer should be able to program a fob for it, but, not inexpensive..... Don't know if the locksmith could do it as well.

 

The locksmith that came out the other day said there is no radio signal coming from the skim halo thingy. He then deduced that my vehicle didn’t have a transponder at all despite what I told him. I think it was disabled or became irrelevant when the ctm was replaced by the previous owner. That ctm did not have the vtss enabled, so there fore there was no factory alarm going off. Sometime later, I replaced the ctm with a used one when my gauges quit working. 2 months later we accidentally manually armed the alarm then triggered it by opening the doors from the inside the next time we opened the truck. The ignition has been able to turn with almost any key that was thin enough to fit the slot as long as I’ve had it. I reinstalled the ctm that was in the truck when I bought it. That immediately stopped the alarm condition (horn, lights flashing), but it still won’t start. It doesn’t sound like it’s getting gas but we have pressure and can hear the pump initialize when turning the key. I’ve never had problems starting this truck. Earlier I posted part of the vtss section of the service manual where it mentions that a no start condition will cause the pcm to have to be replaced. Is that what’s happening here? Thanx

 

Keyless Entry is the alarm
I can't remember what vehicle it was, but one you had to get the fob and do something in both the truck and fob for them to "shake hands" and there was another procedure where you programmed a code (you got from the CTM) into the fob and then they worked. The locksmith was using a Skim key scanner, which won't work on your truck. As most 2nd gens don't have a Skim key. Call an older locksmith if you can one they was around when these trucks where.

 

Procedure for 'mating' fob to truck should be in the service manual, but, I think you need the DRBIII to do the first one, if you don't already have one that works.

 

I reinstalled the previous ctm and that turned the alarm off. Still won’t start.
