problem with remote starter cranking

I just installed a Code Alarm 5051 remote starter/keyless entry into a '99 Sunfire. I'm having a problem with the remote start and am a bit baffled. I hope you guys can help me out. Here's what it does. It initially attempts to crank, which works, but it stops cranking momentarily just before the engine actually starts. I thought this was something about the tachless smart cranking so I set it to a fixed 2-second crank. Now it cranks for a fraction of a second - just enough to almost get the engine going - but then it stops momentarily before attempting to crank again, at which point it's too late. I realize it's hard to describe. It's kind of weird. Does anyone have any idea what might be going on here? Here's a link to the system: http://www.audiovoxproducts.com/code-alarm/remotestart/?sku=CA5051

Try leaving your key in the ignition then tell us what happens.

You need a bypass. Howie I dont think putting the key in the ignition will help. The chip is in the ignition tumbler on those, not on the key, from what I remember. you are way more knowledgable than I am so definitely not saying you are wrong and it wont work. I just dont think it will.

JS, you're quite right but I was just confirming what you said, if it started with the key in then it was going to be a case of "you need a by-pass".. Much easier in Europe EVERY vehicle sold in the European market had to have a factory transponder from 1/1/97.

Thanks for the replies. Sorry I haven't posted again sooner - the car is my girlfriend's and right now I only see her on the weekends. I believe I have a bypass module. I ordered the system from Auto Alarm Pro, and it included the Code Alarm box, a FlashLogic module that hooks into the Passlock wires, and a door lock module. I tried using the remote start with the key in the ignition and in all three positions: not turned at all, to the "ACC" position, and the "ON" position. It did the same thing in the first two positions as it did with no key: start but immediately die. In the "ON" position, it did not attempt to start at all. Here's a link to how the module is installed: https://dl.dropbox.com/u/12873062/IMG_20121202_131925.jpg Here's a video of the car trying to start: http://www.youtube.com/watch?v=atuNAHUW-cU

Oh, and there is definitely no chip on the key for this car.

Fine, diagnostics done , basics, tach wire connected and programmed? DMM to test voltage at ground and fuses, R/S side of fuses. List of unit wires and what's connected to what on the car please.

Older GM vehicles do not have a chip in the key, as i said earlier. They are in the ignition tumbler. You should tell us which wires you have connected in the vehicle. It sounds like your bypass is wired wrong or not working. If you start the car with the key and then remote start the vehicle (pit stop mode) and take the key out , what does the vehicle do?

I don't have a tach wire hooked up. If I have the key in the "ON" position the remote starter does not do anything. I have the bypass wired exactly as in the wiring diagram. I will go down and take a picture of the Passlock wires. I don't have a DMM here, but I do have a test light. I will have access to a DMM next weekend. I tested all the connections I made using the test light, except for the Passlock yellow wire connection. I have no information on what it should read and when. Here's a list of connections made to the Code Alarm box: Solid black from system to self-tapping screw into body Solid pink from system (ignition 1) to solid pink on ignition harness Pink w/white from system (ignition 2) to solid white on ignition harness Solid orange from system (accessory) to solid orange on ignition harness Solid purple from system (start/crank) to solid yellow on ignition harness Red and white w/red (constant +12v) to solid red on ignition harness BLACK/ white on flashlogic (starter) to yellow on ignition harness Green on flashlogic (bulbtest/2nd starter) to black on ignition harness Pink on flashlogic (ignition) to pink on harness Yellow on flashlogic to yellow on the 3-pin harness under key cylinder The other connections are all lights, horn, and door locks, all of which function as expected. Could this even be a Passlock problem? I thought that if the Passlock was preventing starting, it would not crank at all.

Do you have your ground while running wire from the r/s to the bypass. That is what activates the bypass during remote starting. Again if you start the vehicle with key, and while running activate the remote start and then take key out of ignition without hitting the brake, does the vehicle stay running.
