cx2300 series cranks,starts,stalls

Guys, i have a 2007 gmc with a 2300 series remote start.  a pkucg2x bypass module. remote start cranks, starts breifly stalls and contimues to crank.  does this 3 times.  i have tried with the key in the ignition and with the key in the ign it cranks but does not attemp to start. When the remote makes its first attemp the dash lights up and the fuel pump cuts in for a few seconds the it attemps to start.  it seems as if the pump is not cutting back in when it briefly starts.  really fustrated and any help would be good.  THANKS

Looking at your last post from the prior thread on this car / remote starter / bypass...

Did you change anything from then?   Did you verify the wires with a Digital Multi Meter?

First - there is no need for the remote start ( CX2300 ) to be connected to the start wire and the ECM.  Disconnect this.

If you are going to use the PKUCG2X, then you need to follow the Install guide for the Type D install.  Did you add the ACC2 circuit?  Did you connect to the Resistor Code wire as illustrated?  Did you program the PKUGC2X as per the install guide?

The method of install described by Jim Hunter does not use the PKUGC2X bypass.  It uses a "key in the box" with an extra programmed / working key.  It would be advisable not to mix the two different methods.  Do one or the other.
