Mitsubishi Repair: No spark, primary resistance, eagle summit


Question
The voltage I was referring to was the input voltage to the coil.  The coil itself is in the distributor housing under the distributor cap behind some other parts (there is no center wire on the cap since the "wire" is internal to the cap).  I don't think the rotor can be put on 180 deg off, but I will check.  I had no spark prior to replacing the distributor cap & rotor, but it had some corrosion so I decided it would be best to replace it.  Several days prior to the no spark, the car was having difficulty starting (took several attempts), but once it was started it seemed to run fine.  Also, the alternator was making some "screeching" (internal bearings?) while under heavy load (i.e. first few seconds after it was started & after lights were turned on).  I can't find any info on what the coil diagnostic resistances should be.  Thanks for your help.

1995 Eagle Summit AWD Wagon 2.4L.  Car will not start.  Engine turns over but no spark.  Spark plugs are wet.  Replaced distributor cap & rotor & new spark plugs.  Voltage at distributor connector is 11.2v with ignition on and 9.4v with engine cranking.  Ignition coil primary resistance is ~1 ohm between each of 3 connector tabs & secondary is ~15K ohm.

Hi Dana,

It sounds like you're telling me you have voltage out of your coil going to your distributor. I'm not sure if the vehicle was starting before you replaced the cap, rotor and plugs but,as the Summit is a twin to the Mirage, my guess would be that you have the rotor installed 180° off.  Try removing your cap and flipping the rotor around. I know for a fact that on the '95 Mirage it's possible to install the rotor backwards (been there, done that). If that doesn't help, I'd try replacing the coil next.

Hope this helps and Good Luck!

Answer
I'd check the coil and see if you have output to your distributor. I must admit I haven't worked with internal distributor coils but if you have current into the coil and nothing out of the distributor, you've definitely zeroed in on the problem.

As for the screeching, it could be the bearings but I'd go with tightening or replacing the belt first. Loose belts will make that sound...and not always consistently. A/C belts, for example, will often screech only when the A/C on.

Good luck and let me know how it goes.

Follow up:

You've stated you have voltage to the coil and no spark so you choices are few but concise. It's either, in order, the coil, the rotor, the distributor cap, the spark plug wires or the spark plugs. As you've replaced the cap, rotor and plugs it can only be the coil or spark plug wires...or in improperly installed rotor. As you made no statement that you checked the output of the coil, I suggested you replace it. Perhaps you should try new spark plug wires. And it IS possible to install the rotor incorrectly on my vehicle. What more can I tell you without being there to look at the vehicle?

Good Luck!
