No spark after the distributor

Post by Kledith »

Hi I have an 1992 na with an 1999 engine which now has no spark after the distributor got spark getting to it just not passing through. I was driving normally through town when my car decided to cut out, all electrics still working just the engine cut out and wouldn't start again turns out my distributor cap had come loose and the rotor arm made a mess of the cap with melted plastic all around the outside of the rotor arm which I assumed would be the problem. So far have replaced the cap rotor and new distributor just incase was messed up internally, coil pack, king lead, plugs, ht leads, fuses. But still not getting any spark after the dizzy at at lose at what would be causing the issue also my check engine light is constantly on when trying to bridge the diagnostic ports so not sure if that has something to do with the problem.

Any help is greatly appreciated as my mechanic is tearing out what is left of his hair trying to find the issue

I saw the mess the rotor caused when it decided to leave it’s home. Just wonder if the damage caused a fault with igniter. May look ok without a load but when connected to plugs it Short’s to ground?

Hi Jim thanks for the reply is there a way to test to see if the ignitor is faulty as they aren't cheap if its not the issue. Another person said could be the ecu but had a quick look and looks brand new inside no obvious faults

BGB has the required tests for coil and igniter, would start there.
Distrubutor itself could also now be faulty, think it has a built in timing sensor which could be damaged.

Thanks for your reply I have replaced the complete distributor with a fully working one but no luck will get the mechanic to test the ignitor and hope that is the problem

If your getting a spark on the king lead going to the distributor and nothing coming out, then it can only be a faulty rotor arm, distributor cap or plug leads. Have you checked each individual plug lead to see if your getting a spark at each one or indeed any of them

I have had a no start problem before after doing a head gasket. Replaced dizzy, cap, rotor and leads before I found 2 of the 4 new NGK spark plugs o fitted were duds.

Also engine is cylinder 1 timing belt end so this needs to be tdc when rotor about to strike 1 on the dizzy cap. And check firing order on the cap.

The ECU diagnostics may be down to wiring errors when the engine swap was done.

I have tried 2 different brand new rotor arms caps and a whole brand new distributor with no joy plugs all spark on a different car as well as the leads just nothing on mine hense why I'm asking for advice as the usual stuff hasn't worked

Car was running fine before the issue so don't think the engine swap is the problem as was done 7 years ago same mechanic working on the car now. I did suggest the ignition timing but he seems to think the car should run with bad timing just badly

Even if the timing was out you'd get a spark.

Check the coil and igniter properly, you may be getting a weaker spark at the king lead than you should so by the time current gets to the plugs it's not strong enough.

Just as a double check, take off the dizzy cap and make sure the rotor is moving when cranking.

Also I have had a brand new pattern rotor arm not work before!

Also worth checking the earth's for the engine. Iirc there is one under the inlet manifold that might have been taken out by the failure.

Also just spit balling here but are you sure your getting fuel. Spray easy start in the tb to see if it makes a difference.

Thanks for the reply I've Already checked and the rotor is spinning when cranking not sure how fast its meant to spin but is moving steadily. Mechanic is starting to think the engine is f***ed as has developed a metal squealing noise when turning over will get him to get the car on the ramp to check to earth's again but engine seems to be earthed as will cause a spark when putting the king lead next to the block definitely getting fuel as can smell it and the plugs are wet after trying to crank
