hello. i have a 2001 gmc savana and i had it parked for 5 days and when i went to try to start it, all the cluster gauges maxed out, and it just starts and stalls. the security light is not on. i had it at the dealer for 2 weeks .here is what i changed so far. fuel pump, fuel injectors, distrubutor,sparkplugs, cranksensor, upper intake gaskets,and lower intake gasket and apperently my pcm is good. i was told by the dealer that they couldnt figure it out. just wondering if any1 had issues like this.
