mondial misfire

i have checked the archives and i still need help. the front bank 1 to 4 has stopped fireing. i have took the spark caps off and ther is no spark. i have checked the rota arm and the distirbutor cap and the leads and all seems ok.but when i take the lead from the disributor cap to the coil there is a lot of sparking between the lead and the coil any ideas. kev.

 

What happens if you swap the coil lead with 5-8? Does the problem move?

 

i have switched the coil wires from front to back i have got sparks from the front coil going to the back i have put the back coil to the front and have still no spark. this indicates that the coils are ok i have cheaked the lead from the destributa cap and it looks ok. the rota arm goes round when turning the engine and looks ok. any ideas kev

 

The rotor may look okay but how are the points on the cap? It sounds like you need a new cap and rotor.

 

I have still got the same problem 1 to 4 not running check flywheel senseers and the pins on the flywheel all ok the coils have been changed from front to back 5 to 8 run ok.I have run a lead from the coil to a spark plug and it sparks like mad so the spark must be going to the distrbutors. I have check the rotor and all look ok i hope someone can help please
desperate Kev.

have you swapped the caps over? its an easy way to check if the caps worn out

you could also try swapping the ignition ECU's over...mounted low on the passenger compartment firewall by the clutch slave cylinder

 

When you "checked the lead from the distributor cap" does this mean that you actually confirmed a low DC resistance measured between the coil wire metal terminal end that goes into the coil and the brass terminal inside the dist cap that holds the carbon brush/spring?

IMO, with the symptom you report, it wouldn't hurt to remove the carbon brush/spring and the setscrew holding the coil wire, trim off the coil wire at the old pierce hole, reinsert, and repierce with the setscrew (and then measure the DC resistance to confirm OK -- should be something like 700 ohms/ft of wire length if using the stock F wires).
Also gives you a chance to confirm that the carbon brush is in good shape and free to move properly.

 

check the supressor resistance .check for a white powdery substance around the plug connection area.is this the type that screws out of the lead. but 4 at once.did it do it suddenly or slowly deteriorated.hasnt got wet has it.check connector plugs maybe.injector earths on that bank.blank off brake booster pipe connection.could be a major vacuum leak causing a lean mixture.hard to say.funny its on that side .havent put any plugs in and then problem developed(closed gaps--wrong firing order) cars eh. what do you know about f1s. kidding . cars eh. they all go in the end.

 

Each bank has its own ecu controled by its own crank position sensor. They run as to total different systems. If you feel the need to start swapping things round swap the ecu plugs over (on baulkhead left and down low).
