1991 sonoma 4.3 liter v-6

Okay lets start with, are you getting fire?(a spark at the plugs). you can buy a spark tester at an auto parts store for under $20.00. just follow the instructions, most are simple to use. there are other ways to test for fire but they are unsafe. it involves an open spark and high voltage ( if you do have fire). you would remove a plug wire an attach it to a spark plug that you are sure that works then lay it on the engine where it will be grounded. on something metal. then have someone start the car and you look for a small spark at the end of the plug it should be intense blue.dont let this little spark fool you, if you touch this plug while its firing you will prob slam you head against the hood of the car and or **** your self just a little. if you have a fuel leak all jokes aside, that spark will be more then enough to ignite it in a blink of an eye.
