Hi.  New to the forum, found it through a google search, I didn't now places like these existed.  I'm taking electronics engineering (technologist, 2nd year) and think I'll be spending alot of time here lol. 

My question is, I tripped the Passlock system on my 97 Sunfire (by mistakenly pulling out the alarm fuse when trying to install a remote car starter) and now can't get my car to start.  I've tried disconnecting the battery and leaving the key in the 'run' and 'forward accesory' position for 20+ minutes, but everytime I turn the key to the 'crank' position, the car starts, the idiot light 'theft' starts flashing, and the car stalls after 2 seconds.  I've disconnected the remote starter completely but still get the alarm and stalling.  I found a permanent 1 relay Passlock disable schematic, but don't get any resistance when checking the key side of the cut yellow wire to the middle black wire (actually infinite resistance) Now I read somewhere that you have to measure the resistance with the starter disconnected and the key in the crank position? (contrary to the instructions I found off the net).  I'm at a complete loss and haven't been able get any help from the dealers at all (big surprise lol).  I would appreciate any help anybody can give me.  Thanks.

Just to add, I've done multiple searches through the site to avoid repetitive posts but couldn't find this exact topic.

I've yet to actually install a bypass setup for this type of vechile that requires to hook up the bulb test wire, but anyway i've found that using a 555L from directed and even a PLXR module from bypasskits.com actually work better. Esp. the PLXR module because with that setup you don't have to cut the yellow passlock wire it just taps into it.

Try starting the car and let it stall. Don't turn the ignition key to the off position though. Let it remain in the run position until the security light on the dash stops flashing. After the light has gone out, turn the key off and try to start the car. If it fails to start, leave the key in the run position again as before until the light stops flashing. You may have to do this three times before the car will start. This should work unless there is a defect in the Passlock I system.

One other thing first. Disconnect your relay if it is still hooked up. This won't work. Invest in a proper bypass module and save yourself alot of grief.

I just went out and tried starting it this way (with everything set back to stock), fired the car, waited for it to stall, then left the key in run and for the alarm to stop flashing, then turned it off, and restarted and repeat 4 times and it still does the same thing.  It did flood after the 2nd try so I had to wait a while in between but I left the key in the run positon the entire time.  The car always worked great before this so I really can't see how anything would be wrong with the system?

thats pretty close, but you have to leave all of the doors shut and sit for 10 min with the key on ignition (all the way forward with out cranking).  if its been seriously tripped, which i think is like 3 times in a certain amount of time, you might have to take it to a dealership.  ive seen that happen on a PK3 grand prix or something.

i really dont know why someone wouldnt just buy a 555L.  it learns the resistance and sends it out for remote start, and it leaves the factory system functional for the key.  i hate that about as much as i hate people whos idea of a VATS bypass is cutting the wires and crimping the resistors across the car side ends and calling it done.  if that sh*t breaks the key and remote start wont do jack.  maybe they will be on the way to the hospital or something.  who knows, its always better to just do it right.

dont let the car fail start more than once in  row, and you wont engauge long tamper mode.

after every fail start, abort the R.S. attempt, wait ten seconds, and key start the car.

Thanks everybody for the help.  I tried it both ways.  Just now I disconnected the battery for a while and then turned the key into the run position for about 20 min (leaving the door closed the entire time).  As soon as I cranked it over it tripped the alarm again.  I tried leaving it for a while still in the run position and again it tripped the alarm while cranking.  Shouldn't resetting the computer reset and hard tamper alarm?

As for why I didn't install the other system, I kind of went into this blind and didn't know anything about the anti-theft device, if I would have known, I never would have bothered.  I got the remote starter for 1/2 price and thought it would be a cool little project.  My wife and I are both full time students and certainly can't afford spending a bunch of money on gadgets.  Right now I could care less about the remote start, I just need my car to run.

If now you want the car to function like it should normally then just reconnect the yellow wire that you cut for the passlock system. Once you do that the car will function like it should normally.
