Could be fuel pump, fuel filter, air filter, o2 sensor though not usually all of a sudden. could also be that the distributor may have loosened and turned a 16th of an inch or more which would have caused this as well. check this by making sure your number one plug wire on the distributor is toward the number one plug on the motor. also you could have jumped time. check your belt or chain.

97 chevy blazer rough idling problem? help?


It is hardly ever the spark plug or only the spark plug - generally for some reason there is a weak or lost spark and the reason must be found and rectified by carefully checking and then replacing any components found to be edfective - plug wires, coil, distributor cap, rotor (if fitted), wiring, connections and could conceivably even be the ECU. Perhaps the misfire is due to injector trouble...

Sometimes a fault with persist even after it has been "cured" until the fault code is erased with diagnostic equipment.

Changed spark plugs in my 1999 chevy blazer and it wont crank over. Gapped the plugs to specs...should I've also changed the wires, cap & rotor also?


When you go to an auto store and they give sell you spark plugs they should already be gapped to spec. There is no need to adjust the gap. This may be the reason your car will not start. I would try new spark plugs first then wires. Since the vehicle is a 99 it probably could use a tune up (spark plugs, wires, coils, cap, rotor, chassis lube, and transmission fluid check and flush if needed). Also make sure that the engine block ground strap is in good condition and that there is no corrosion covering the ends of the ground strap. The ground strap is typically located near the firewall and is directly attached from the engine block to the frame of the car.

We have changed the plugs in my Echo and it is still miss firing please help. No engine lights have come on


Check the spark plug wires, coil packs or cap & rotor whichever the vehicle is equipped with. Most likely you have a bad wire or coil/cap/rotor. Also check the timing if it is out of adjustment it will cause the engine to misfire.

Blazer wont start


You are getting good spark to the plugs? Have to assume you retimed it after you changed the rotor and cap. Wires are good?

Could be the ignition module, but they usually are either good or bad and not itermittent(sp)...

If it trying but just not 'catching'.. seems like a timing issue, or possibly the coil (although coils tend to be good or bad as well)

Take off the distributor cap. Check the star wheel that is splined to the distributor shaft that the pick-up coil uses. Make sure this wheel is not loose on the distributor shaft. It is right above the pick-up. If it is loose, replace the distributor. This is a common problem. If it needs one, all the part stores stock the distributor.
