On the cap the contact points inside will look coroded--not square edges and burnt spots where the rotor fires against,the rotor will look burnt on the tip and have rounded edges(in other words all metal parts in the cap and just the thicker metal on the rotor)the really shinny metal on the rotor will be black in spots where it connects to the cap in the middle but doesnt always go bad there

Installed new engine now wont fire from distributor to spark plugs.


If you've got spark from the coil but not at the spark plugs, it can only be 1 of 3 things.
  • Bad spark plugs or plugs not gapped properly.
  • Bad spark plug wires.
  • Bad distributor cap and rotor. This is pretty easy to check. Open up the cap and look at the points on the underside of the cap and also the point on the rotor. If they look corroded or worn, then you should replace them.

Good Luck!

How to find out why there is no spark getting to the spark plug


probably bad incorrect cap/rotor.
maybe pickup coil but probably not.
pop off the cap look at the brush/contact between rotor and cap, if messy lightly pull brush from cap and also cap use fine sandpaper to clean them, then push brush in till you hear a pop and reinstall rotor & try starting. or replace cap and rotor.

SPARK AT COIL WIRE BUT NOT AT PLUGS

Spark coming from the coil to the cap but nothing to the plugs new cap and rotor still nothing


Take the cap off and watch the rotor turn.
If the shaft broke and the rotor was not turning, you would not get any spark.
Could be the engine ground also came off, so there would be no place for the spark to go.
Plug wires could also be bad, but unlikely they all went at once.

My 400e mercedes is misfiring,and I hear a small metal pcs crunchy sound around the distributor cap,do u think that the rotor cap is bad


Your distributor bushing is bad, causing the distributor to wobble when running. Get it checked out for repair and/or replace the distributor. Take off the cap and check the play in the shaft that the rotor is attached to first.

I have no spark at plugs coil has good spark


If you have spark at the coil then you have a good coil. You can't measure Ohm at a spark plug since it is alway open at the gap. But you can OHM measure a spark plug wire at both end. If you have nothing mean your wire is bad. You can swap one more wire to confirm a bad wire. If your wire is not bad then I recommend to replace both rotor and distributor cap. Good luck in locating the problem.

No spark to plugs but i do have fire from the coil to the distributor


Bad plug wires, distributor cap, or rotor. Pull the cap if the contact points on the rotor or the cap look rusty they need to be replaced. If not try replacing the wires.
