2.0 Mi16 On 3 Cylinders

[allanallen 528 2 Cars]

hi all, my bros mi's suddenly started running on 3 cylinder, no. 2 has no spark but the coil is fine. I put the multimeter across the pins and i'm getting no reading at all, non of the wires seem broken or anything.

 

anyone have any ideas.....ignition module? Also does anyone have the wireing diagram for it (405 2.0 mi16)

 

any help really appreciated because hes driving me insane borrowing my car cheers, al

first off check the rotor arm and cap for the connections, might be as simple as once being worn.

The 2.0 Mi16 has coilpacks and hence no rotor arm.

 

I'd say it sounds like a classic case of a coilpack u/s.

 

However check the plug on the cylinder thats not firing, I've also seen in the past duff wiring to one injector hence no fuel to one cylinder do the same thing. If the plug is piss wet through then you know it is an ignition problem.

 

I've got a 405 Haynes manual but I don't think it covers the Mi16 engine wiring unfortunately.

its defo an ignition problem, theres no power or signal to the coilpack on no. 2, all the others are showing 13 or so volts when running.

 

your right about the manual aswell, what a waste of 20 quid that was

if you want a manual that covers the management system get a Haynes Workshop manual for the ZX, the red one number 1881

 

if you haven't got 12v to the coilpack check the large multiplug on the side of the head.

 

coilpack for No2 is fed from pin 12 of the round plug, if you haven't got 12v at the main loom side of the plug its likely to be a break in the wire as there is a single large cable from Pin 1 of the Relay, which splits into 4 before the round plug on the head

should there be 12v with just the ignition on or does the engine need to be running?

 

Am i right in saying cylinder no.2, its the second one away from the cambelt end

[welshpug 1,657]

ahh no No1 on a pug is flywheel end pin 13 I think it will be for No3.

 

Should be live to the coilpacks on the second turn (same as the injectors)

 

I think Graham has a PDF of the ZX manual, the actual layout is pretty similar just different wire numbers/colours and position of the ECU and relays.

how foolish of me cheers for that, i'll give graham a shout

after my brother had been pulling his hair out for 3 hours he tried swapping the ignition modules over and this cured the problem..

 

what the hell is that all about?
