Check your battery first,  Then measure voltage to the starter solenoid.  No voltage at solenoid the problem is at the key switch.

1997GMC Sonoma 4x4 engine cranks but wont start


sounds like a fuel pump problem. take off gas cap and have someone sit in the truck and turn iginition key to on. (do not turn key as if you were starting but to "on only") you should hear the fuel pump engage. if you dont hear the fuel pump then check the fuel pump relay. it is located behind the glove compartment. hope this helps...

Left blinker problems


That's an issue with wiring somewhere alont the line. There has to be a short somewhere. Hopefully for you the short is from the new taillight assembly being installed and it would be relatively easy to get to. Hope it helps!

99 GMC sonoma will start with starting fluid then


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.
