99 Suburban 1500. Passlock system intermittently causes the burb to not start - perhaps you've seen my post in the "member intro" area - " New from Texas - Haunted 99 Suburban" ??? I am hoping someone here might know of a work-around. We have yet to ID something that causes the passlock system to think it is being stolen, and cuts off the fuel flow. The only work-around that seems to work every time is to wait one full hour and then try, and it always starts. But waiting one hour is not very practical 99% of the time. I read someplace that when it malfunctions, you turn the key to the "on" position, and wait a few minutes, till the "security" light on the dash goes out, then it should start. But, wouldn't you know it, I can't get it to malfunction, so I can't test that work-around. Anyone have any ideas? Thanks.
