Hello Everyone, I have a 1990 Toyota Camry (V6 2.5L) station wagon. It has 109,000 miles on it. I have been having ignition coil issues. I have replaced the coil 3 times in the last year and the car died again last night. I am almost positive it is the coil yet again. Does anyone have any idea…

You need to measure the voltage going to the coil. Too much and/or too little can cause problems and “kill” the coil. It seems you have a number of electrical issues, perhaps the ignition switch is bad. Likely the electrical issues are related so if you find the cause for one, you might cure the …

If I am not wrong your car only has one coil right?? In other words every plug does not have its own coil pack?? Lets assume, one… If it keeps dyeing on you either you are getting cheap poor quality coils (you may want to spring for a new Toyota part), or the coil is overheating. I know on some cars…

The burning up of the coils might be caused from a defective ignition module. The ignition module functions in two modes. These are the start and run modes. When starting the engine the ignition module allows full battery voltage to the ignition coil. This ensures that there’s a hot enough spark wh…

Thank you for your responses, everyone. Uncle Turbo, The ignition switch is a possibility for sure. I agree that the symptoms are likely linked. The new distributor came from Rockauto. A friend who is a mechanic helped with the installation and I am confident (that between the two of us) that ev…

Is this the distributor that is piggybacked onto the distributor? And are you sure that the coils you replace are actually bad? How did you test them?

cont I would suspect the distributor might be your problem. I’m guessing that you got a remanufactured distributor. If so, I would check the shaft for any side to side play. You need to line up one of the vanes on the shaft with the line down the center of the ignitor, then place a 0.010 feeler …

Keith, It is indeed a re-manufactured distributor. The first coil that failed I brought to the auto parts store to have it tested and it was bad. The replacement coils have had large obvious burn marks on them so I did not bother to have them tested. Thanks for the information on the distributor…

When the primary of the coil is opened by the computer, the coil has to discharge. If it can’t find the normal path through the spark plug wires and the spark plug, then it arcs internally. a coil can withstand a few misfires, but if there are to many it will burn up. Large obvious burn marks ind…

Keith, Thanks for your replies and explanation. You are correct the 3 rear ones are very difficult to reach. I am thinking based on your explanation, which is great, that the distributor cap and rotor are probably not the issue–as this has happened with 2 different distributors & caps. I am thin…

If you are burning holes in them, then either the applied voltage is too high or you are experiencing a lot of misfires. Since you have the V6, I suspect that 3 of the plugs are really hard to get at and maybe haven’t been replaced, even though you might have paid for replacement.
