04 diesel dodge.tach

OK, at this point I am losing my mind. We are installing a Python 990 in a 2004 Dodge Ram 2500 Diesel (automatic). The alarm is in and functioning correctly (to include programming) but we can't get it to start. We have tapped Pin 24 of the forward ECM connector, AND tried the pin at the crankshaft sensor. It still won't crank. I know we need to crank it longer than normal, and we have it set for a 4 second crank time. However, to get it to crank that long, you need to shut off the tach sense in the program. At this point I'm lost.....HELP!!!!

Ok, just a couple quick ones to check. Did you reprogram acc state during wait to start on? Also the 990 has wait to start built in so you don't even have to hook that up, it's feature 3-13 for future reference.   Just out of curiosity does it do anything? Acc's, ign's kick on?

Acc state has been tried both set to on and off. Everything seems to be order during remote cranking, but I will double check. There is the possibility we don't have an acc. hooked up correctly. We had to run another wire from the alarm remote module to the fuel relay, because it is an aftermarket fuel system. However, it is power off ign power, so if it's not coming on, maybe we missed something. How many ign/acc wires should be hooked up?
