    Hi. I had the same problem with my 99 suburban. Simple fix worked for me, not sure it will do for you but can`t hurt. (Been playing with vac lines, ect... for weeks - I`m still shocked). Try this. put the key in the ignition and click back and forth from accessory to off about 3 or 4 times, then take the key out of the ignition, put it back in and start the vehicle. It worked - can`t believe it but it did. Hope it works for you. Bob
