Question about Chevrolet Blazer
If your spark plugs have not been changed for many miles, even if you have 100,000 mile plugs, It is highly probable that you just need to throw in a new set. Put a new plug in one of the wires , ground the plug, turn the motor over just to check for spark. Living in Minnesota, I have saved many a neighbor that was late for work by pulling out there old plugs , closing down the gap to the recommended settings, putting the old plugs back in, and having the machine start right up. If this is gets you running consider also replacing the cap, rotor, and, wires. These can all make a big difference in winter.

What I always suggest is take a little starting fluid and spray in the air cleaner. If the vehicle starts then it is a fuel problem. If it doesn't start it is a computer or electrical problem. If the starting fluid starts the truck, then the next step is check the fuel pump. You can do this by removing the gas cap, have someone put their ear down by the fuel fill. And turn the key to the on position. You should hear the fuel pump run for about 5 seconds. This is the most common problem. You have to drop the fuel tank and replace the fuel pump in the top of the fuel tank.
