’03 silverado, remote start wiring

are you testing your wires?

I am also having the same problems with my remote start in my 2000 silverado.

I have the tach wire hooked up to the white wire off the ecm and when i go to start it, it starts and dies and continues to crank for a little while.

Can't figure out whats wrong.

thats what im thinking it has to be. I never even heard of the passlock untill i read this thread.

My truck had an old remote start from the previous owner but i did not get the key chain starter so im putting my own in, so tonight i will try and see if there is a bypass module or not.

Any ideas where this module might be?

ok so i just had a look at my truck.

i found the bypass module

i found that there were 4 wire coming of the module towards the r/s module ( i didnt bother folowing the other ones wherever they go)

i found blue, purple, red and black(assuming this is the ground) wires coming from the module. with no other in formation on this module i have no clue where any of these are suposed to go.
