Question about 1998 GMC Sierra
My truck will turn over, appears to be getting fuel and spark but will not start. It began to run very rough from a stop when I attempted to accelaerate. That problem did not last long before it just would not start. A computer code reader indicates no problem codes. The service engine soon light is on. Any ideas how I can get it started?
I have my husbands spare key and the securaty lite came on and want let me crank it ...i forgot how to by pass it by turning on and off the switch

Well if your service engine light is on I guarantee you will have a code ready to be retrieved!!! are you using a OBD 2 scan tool also are you hooking it up correctly?? and you do have a miss fire but you don't want to be GUE$$ING 1 of ten possibles.if your scanner is not working take it to someone whom has a functioning scanner good luck.
