2000 chev K2500, Start and Die

All,

I am installing an Rs 850-lcd on a 2000 chev K2500 (old style or classic).  When I give the command to start it does so for a brief moment and dies. I can hear the ignition come on and the fuel pump prime and I have double checked my connections.  I am energizing two ignition circuits and a HVAC circuit in the truck so I should have plenty of power where it needs to be.  I am using the tach sense wire and configuration (white wire off the coil).  I have performed the RPM sense mode twice now( this proceedure does not work the way the book says it should FYI) but no luck getting it start correctly.  The instructions read poorly and there is not a troubleshooting section.  Anyone been down this road before with this type of unit?

I installed a VIPER two way last week on my girlfriends Durango with no hiccups.  For what it is worth I think the Viper kit quality was better (larger gauge wire, more on board relays, heavy duty construction, better instructions)

Thanks.

I called autopage because the websites invites anyone to do so with questions and was basically told to "beat it".  I'm not a dealer.  I can understand.  BUT THEY NEED TO STATE THAT ON THE SITE!  This is a cheeseball company and I do not recomend the garbage they produce.

I am off now.  I have a busy day of sharing my AUTOPAGE eperience with as many people as I possibly can.

2000 Chevrolet K2500 ext cab 4x4 with 5.7 vortec and yes, I just found on the window sticker it came with pass lock. My mistake for not checking earlier.  The truck is waht they call a classic due to the fact it was the last year they manufactured the previous body style as opposed to what is currently being produced.

I don't know how this pass lock works but I can tell you the key I have for the truck does not have a bump in it and the one I had made at Wall mart works just fine. If that helps how do I get around Pass Lock? I know there are several smal gauge wires at the key switch that I probably need to wire to the RS-850-LCD but how?

Thanks
