I have a 99 GMC Suburban. It has an intermittent start problem... perhaps one time per month. I've replace fuel pump and filters. I can hear the pump run. The engine turns over as if burning a prime of gas and then stops. I've also notice (sometimes) that the security light comes on prior to this happening. It also occurs more after a rain than good weather. I was told to turn the ignition on then turn it off. Repeating the procedure three times. The problem is that I can't remember the length of time for each. I believe it is supposed to re-set the computer. Can anyone assist?
