What is the procedure for checking you coil to see if it is working properly after the engine has been runing and warmed up? how much should I expect to pay for a new coil?Thanks in advance for your help.

I have always known to check coils by testing the resistance between the terminals on the coil. Usually there are specs for this but I don't know what they would be. It doesn't have to be warm. Usually if the truck runs I would say it was good, but it could be producing weak spark. Just depends on what your problem is.

My truck is a S83P-137357 type V-S83P-TRK It is a 1993 I just got it knowing it had a problem starting. The previous owner said at first it would not start after it would rain. Then it changed to just about anytime it took the notion. It will start most of the time when the engine is cold and run for about 10 minutes then it will start to bog down. Then when you step on the gas pedal it will hesatate then pickup RPMs or else diy then that is it,done. I took the plugs out and they were all carboned up ,dry and not wet.

Allan57, I would change the plugs and check the coil. It wouldn't hurt to change the distributor cap and rotor. I assume this truck does not have points. Also the biggest problem I had was the timing. I would check and see if the timing is correct. Also make sure you are getting gas to the carb. You have got to determine if it is fuel or a spark problem. Leon is at Daihatsu help today and he could help you. 626-968-6764
