How is the ignition module? PO300 is a multiple misfire code. It can have many different causes. Coil being one of them. The 4.3 motor that you probably have is susceptible to the (sometinmes called: octapus or spider) fuel injection unit that set on top on the engine. I believe there was also a poppit valve problem on them. Do rule out basics like spark plug or ignition wire or poor connection at the coil from corrosion. you have to reset the computer and see if it still comes on then check the injectors
The pad on the clutch is getting low
see where the wiring loses power. trace it back, starting at the pump, and go all the way back to the relay
check your distributor some of your cylinders are not firing or just get a new truck
The starter on a 1998 GMC Sonoma is replaced by disconnecting the battery, removing the outer cover, and unbolting it from the engine. The wiring harness can then be disconnected, the starter removed, and a new one put in place.
In order to unlock the radio of a 2000 Sonoma, first start the car. Then turn on the radio. Using the minute and hour buttons, enter the code that you already have. Then, press the AM/FM button.
