python 1500esp not starting

I just installed a python 1500esp in a 1996 hummer h1 and I am having problems with the remote start not working. Everything on the alarm works except the remote start. When I engage the remote start it waits for the wait to start lam to go out and the the starter engages for a split second then stops and all accessory and ignition power quits at the relays. Any help would be greatly appreciated. Thank you Ryan

Also I have tried with and without engine checking also with tach sensing and voltage sensing and I get the same results each time. Thanks Ryan

Is there an immobiliser involved? Try it with the key in the ignition.

There is no Imobilizer and I did try it with the key in the ignition. Thanks Ryan

Increase crank time?

I set it to the max for crank time and as soon as the starter kicks it stops. It is like the starter is overloading the system. I even jumped the starter at the alarm relay and it cranks no problem. Thanks Ryan

When the starter quits cranking it also kills the ignition, second ignition and the accessory relay as well. It's kind of acts like the brain gets overloaded. Ryan

Strange, have you thought of running some heavy gauge wires to the battery or checked the voltage between the pos wires and the black neg?

i ran across a truck once (best buy installed it) that had a hood pin switch that was adjusted too close. did the same thing. the moment the starter would hit, the hood would shake just enogh to kill the whole system.yuk

If your system moves you physically and not emotionally, you have wasted your money.

Nice one, and of course that wouldn't show up on pre-start diagnostics. Try opening the hood and holding the pin down, also use a DMM on continuity to make sure it isn't grounding somewhere.
