Chrsyler Pacifica shuts off after a few seconds with remote start

Question

Installed a Compustar CS300 with a Fortin INT-S+, used the suggested #7 install instructions from the Fortin install sheet. The vehicle will start for a few seconds then shut off. I took the INT-SL+ out of the car, hooked it up to the flashlink module and flashed it to 3.06 firmware. Once back in the car, held down the program button and plugged in the module, LED illuminated. Then plugged in white connector and LED stays lit. Press lock on the remote start and it goes off. Turned the key to Ignition and the LED never blinks. Still wont keep the car running. I don't think it's "learning" the car? Tried locking the doors and starting, when it shuts off the red security light on the dash blinks two fast then one.

Answer 1

Try without datalink, so cut the blue and white wires from the datalink connector. Also, ignore the step that says to press lock on the remote starter remote.

For the wiring, double check the orientation of the yellow and yellow/black of the int-sl+.

For firmwares, I would actually try the 0.55 as its specific to that exact problem.

Comments

Do I still hold down the black button when I plug the INT-SL back in, then the white plug?

I flashed it to .55, 3.0 and .3. Tried them all with blue and white unplugged, not pressing lock key and waiting. Then tried with lock key and waiting. Then I plugged blue and white back in, didn't press lock and waited. Then pressed lock and waited.

Still nothing.

LED stays on constant with .55, it goes off with .3 and if I remember right stays on with 3.0. I noticed after buttoning everything back up after starting it with the remote start and turning it off, the security light blinks. Then I cycle the key off and start with the key again and they go off?

I have yellow/black going to transponder plug side, then purple going to transponder plug side. I have yellow and pink connected together going to car side on transponder. Purple/White goes to ignition plug side.

I am pointing my finger at the purple/white and the purple wires. You mentionned "plug side" for these connections. I think i am reading it wrong but, something may be going on here. 

 

The int-sl will program mainly on the Purple and Pink wires. You should be able to put a meter in Vdc on that purple wire and read some voltage with the key on; about 1.xx - 4.xx volts. 

 

0.55 or 3.06 should definitaly program on these vehicles.
