2005 Chevy Express Van Remote Start

I am totally unfamiliar with this "valiant" system but what you might want to do is try this.

Put the key in the ignition and then try to remote start. If it starts the problem is with the bypass mod. If it still does not crank you need to check the wiring and to make sude the neutral safty switch wire (if not utilized) is grounded, the hood switch is NOT grounded when the hood is closed, and the brake wire is NOT showing 12v+ when the brake is not depressed.

Also note many RS systems REQUIRE programming (tach etc) before the unit will do anything. Read the instuction manual carefully.

If all is not working after this use a meter to see what is happened with the RS outputs (ign, crank etc)

Thank you again.  In addition:  I got the starter to crank.  The reason was I didn't use IGN 1.   I went directly to IGN 2.  Now I'm energizing IGN 1 from unit and IGN 2 thru relay.  The problem I am having is I cannot read the OHM resistance.  I went from small blk to small yellow cut and reading keyside.  I now tried it from tan to small yellow.  Neither wires gives me any resistance reading.  Am I possibly using the wrong wires on vehicle IGN harness?  So far I saw about 4 diagrams showing colors and these colors are not in my harness.  Are there any other wires I should be reading resistance from so I can set all dip switches in by pass module?

Passlock II anti-theft security system

Vehicle starts and shuts off immediately and the security lite flashes on dash.  This leads me to believe the resistance is not operating correctly.   From what I understand, the Passlock II anti-theft system shuts off fuel through resistance in key module.   Thank You for any help......

Thank you Cruisin S & S,  I checked the resistance from the yellow wire key side and went to blk wire.  I didn't get any resistance.  Do you want me to put van in reverse and check this?  I start van with remote and it starts & shuts down instantly and the security lite flashes.  Then I start it with the key to clear up problems.  Why am I not getting resistance reading?  I tried 3 different OHM meters.  Then I tried yellow wire key side to tan wire.  Still no resistance.  I haven't tried 3 times unsuccessfully in a row, so I didn't lock up the passlock II module yet, but thanks for that tip.  Please help, as I am at my wit's end with this problem.....thanks   Cell phone #630/843-2061 feel free to call

Chris Luongo, thank you, your last tip is what did the trick.  I had the wrong yellow wire connected.  There was another yellow wire in the harness, but it was yellow and white striped, so I thought it was not the correct wire.  Turns out it was, after I completed the test.  Thanks again, and thanks to everyone else who posted; all the advise helped a great deal.  What a great site this is..........Big Al Z
