    no. the problem is when you pull the coil wire off there is no spark coming from the coil. so it's not the plugs or wires.

    well, we finally broke down and took it to the shop. turns out it was the cam sensor. go figure. also something had gotten under it and chewed up a bunch of wires. thanks for the help!

I have power to my coil but none coming out on my 84 351 Windsor brand new distributor coil is good module came on new distributor I need help ?


Since the coil is getting power you need to get a spark tester or pull a cord of one spark plug and lay it on the engine and have some crank the engine. You should see and hear a spark. If not check fuses and check the ignition module - that is the device that tells the the coil to send a spark. You could also remove the wire from the coil to the dist cap and look for a spark.

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.

My geo will turn over but will not start. It was parked and then an hour later would not start. a fuse in the fuse box on the fender is burnt out and it says am2 on it . I do not know if this has...


I'm not sure what that fuse means but it would be a good idea to change it. If changing the fuse doesn't fix your issue, your problem may be in the distributor cap or ignition coil.  I would check these parts first before trying anything to in depth.  The way to check the coil is to take the lead coil wire that leads from the coil to the center of the distributor cap.  Take this wire off at the end of the distributor cap and put a spark plug inside of it and lay it on something like the intake of the car.  IT MUST BE METAL AND GROUNDED!!! Then turn the key on and crank the engine while having someone watch for a spark.  If you don't get a spark next use either a test light or a voltmeter and check to make sure you have 12 volts to your coil.  If you do have voltage to the coil and no spark, then it should be your coil.  If not then you need to move further into the workings of the electrical system.  
Any questions, just ask!!

You may want to remove spark plug to make sure you are getting a decent spark .a nice strong blue and usualy easily visible and not weak yellow spark thats hard to see .if you have a spare spark plug no need to remove one from engine.Make sure you have a good 12v source of power to the distributor.Is your distributor electronic?should be but if points based instead you may find its time to change the points.Also your coil needs to be checked by removing the H/t lead to the distributor and checking that the coil is producing a healthy spark.Coil and spark plug test is done while some one turns engine over while other person watches. while testing do not touch while cranking as you will get severe electric shock if you do .If coil produces poor spark check you have 12v into the positive terminal while cranking if that is the case the coil needs replacing unless the points are no good,if fitted and not electronic.Let me know how you go and if you have no luck starting glad to go further with help and advice
