No spark, just put in a new coil, distrbutor isnt dirty or wet, sombody told to check out the littl box's on the fender well, what are these to box's and what is there purpose? Mike 77 cj-5 304 3spd I have put in a new coil, rotor, wires, cap, and plugs. Still not getting spark. I replaced the ECU (Box on the fender). The only thing I can figure is it's the ignition module, but I can't find it on the distributor. The wires go to a magnet, but no points, or anything else.. It ran before, and I haven't replaced anything besides the cap and rotor on the distributor. I get 12v at the coil, and with the key in run position I get 7v into the cap, but no spark gets to the plugs. I have the 4.2l straight 6 engine, with a carb, all stock

I had the same problem with my 85 cj7 this week, I relpaced the ignition control module, plugs, wires, cap, rotor and the the coil; still had no fire to plugs. the problem turned out to be my distributor, replaced it today and she fired right up. Most likely it was the pick up module in the distributor that went bad.

When you change the distributor and the spark plugs, you need buy NEW spark plug wires as well. You cant use the same wires on different Distributor and spark plugs because it wont work.

Think the oil pressure switch keeps the fuel pump running once started. Suggest replacing Oil pressure switch. And no it won't effect oil pressure reading when it goes bad. The switch is a safety device. When you roll it over and the oil pressure drops the switch cuts off the fuel pump. Neat huh? Need some good feedback Thanks!

No spark to spark plugs 1600cc , wires are fine , fuel pump ok , spark plugs wet, could it be distibuter cap , or module , or distrbutor itself
It is possible that the distributor cap and/or rotor are faulty. They are not very expensive, easy to replace and will allow the engine to run more efficient. This is a way to visually test the coil to make sure it is good. Remove the coil wire at the distributor and place it against the engine block so the spark can find a good ground. Have someone turn over the engine for only a second or two and keep clear of the wire. You will be able to see how powerful the spark is or if it is bad. Please rate me on this answer.

Low battery voltage can keep the coil / ignition control from firing. You need a good 12V to get everything working right. Get a full battery charge and try again. It might also be flodded by now.

Engine ran fine stopped at red light it just stopped running.
Make sure the modual and coil is getting fire and that the engine is got good ground. But it sounds like you got a bad coil.

You are posting your reply in the wrong place but I accidentally found it. Check the ceramic resistor block (usually on the firewall, drivers side or on the fender, same side) and make sure it has continuity If that fails, ignition will not work. Also check that you have voltage to the coil.

1990 jeep wrangler has no spark
I think what you have is an in-between model for which I have no good information. Do a coil test using an ohmeter...(regardless of what it's on a coil is a coil) If it fails, replace it. Also check to see what is used to trigger the coil. there is likely a trigger in the distributor and a control module (possibly mounted next to the coil). sorry I dont't have better info...it happens sometimes.
