Question about 1998 GMC Sierra

1 Answer

99 GMC sonoma will start with starting fluid then

99 GMC Sonoma 4.3 will start with starting fluid then runs fine but won't start on its own. I have a 99 GMC Sonoma that will turn over but won't start. I hook up to the OBM but can't get a reading at all. I was it has something to do with my aftermarket alarm or my factory alarm preventing it from starting. I have had this Clifford alarm for over a year with no problems until yesterday. Thanks

The 99 GMC, when it acts up, check whether it has fuel and/or spark. It could be related to fuel pressure, available electrical power, ignition component/s.
