Ignition Coil problems

I have replace all 6 of the ignition coils on my 2002 chevy Trailblazer twice in the past year. They have started going bad again. One will go bad, I replace it and within a day or two another one goes bad. I change all the spark plugs during the summer and that seemed to help for a while. Then here we go again. They started going out again for the third time. Any suggestion?

Hi, the reason for the engine to die when you turn, is because it make more effort while turning ,this is part of the same problem, if you dont have presure some times it can be the pump ,be sure you hear the pump runing when you turn the key yo on position ,if there is no sound ,check fuses and relay ,if every thing checks ok,you may have a bad or defective pump ....

It might be a long shot, but i have a 04 cavalier and i once smelled gas and had a putter issue. Turns out the fuel pressure regulator basically sits on the fuel rail with one screw on the side. Over time, the regulator either goes bad or becomes unseated off the fuel rail. In my case, both occurred. Went to O'reillys, bought a 48 bux fuel pressure regulator and replaced it. After that., no more gas smell and no more putter.

You could also have a bad idle air control but this would not cause the smell of fuel to occur, unless this bad valve is causing your pc to spit out an excess of fuel which is being unused or somthing.

2003 Pontiac Vibe - 4 Cyl. 150k miles. Ignition coils keep going bad - every 4-6k miles. Coil 1 has been replaced 4 times, Coil 3 once. Coil 4 twice in the past year (20k miles). All spark plugs


Install new spark plugs, 4 new coils & replace the oxygen sensors

O2 Sensors are only good for 100,000 miles, then slow
down or quite

No idea why the coils do not last 5 or 6 years

Cylinder #1 is always at the front on a 4 cyl

Go to Rock Auto --Buy Wells Coils,NGK Double
Platinum Plugs & NTK O2 Sensor

Those parts are expensive because you have a Totota
Motor I guess

{: ) It is the engine control module that gives signals to ignition coils . Visually inspect the wirings for the #1 cylinder. But I still suggest that your vehicle be thoroughly scanned to monitor the different parameters and data present on your vehicle.

Replaced clogged 2002 grand am inline fuel filter. Engine turnes over and attempts to start but will not crank. The engine is receiving plenty of fuel. Could the computer- ized engine timing be off? If so,...


try drying out the plugs possibly flooded,, if its flooded try drying the plugs out and let the engine sit to dry the cylinders out.. the timing never goes out on computerized ignition, replace the plugs and ignition wires and test the coil resistances. 3 coils test between each coil where the ignition wires go KEY OFF, they should be 5 to 6 thousand ohms each if not replace the bad coil.. also did you pinch the fuel line check it for kinks ...good luck

There is a module in the ignition cap that is known to go bad. If it is this part, your truck will almost turn over, but not quite. I would check there first. Once you get it out, one of you local parts stores can test it.

How do you change the ingnition coil for a 2003 chevy trailblazer


it would not be the ignition coil....injector cleaner could help it, most people add it to the gas to help maintain clean injectors and you should do the same. as far as the coil no leave it alone.

1983 GMC Seirra blowing ignition modules


Another person (mountainman1) had this same problem with the HEI he found it to be a bad ground connection at the coil in the cap. When he would replace the module after replacing the cap it would make a new connection for a couple of days then go out again. I do not know if this is your problem but it sounds the same.
