made for an interesting read, my leads are run of the mill landrover jobbies, my distributor is new and spark is good but i know what he means about plugs my engine can ruin a set in 10 mins!!!!!
Hi AlCould it be that simple??? his car sounds just like yours and mine and am pretty sure the last owner put new leads on my car, quick question mate, do you know what the output at the plug end of the leads should be as this would confirm both dizzy and plug leads are putting the correct voltage out?? worth a try mate
Ps have you unplugged the coolant temp sensor and put a 200ohm resistor in as when mine had the efi it cured the rich running, if you need a resistor just give me a shout i have a few somewhere mate, long shot but you never know
I,ll keep on looking mate and see what i can find
Cheers

not sure how i'd measure output at plug end? would the voltage not blow my meter up!!
coolant sensor is new but the only way to get the car to fire up now is by unplugging the thermotime plug and putting it on the coolant temp and shorting out the temp sensor plug, i've also checked the continuity of wiring as i understand this is an important earth for ecu.
on a lighter note i took simboy's advice and moved onto working on a little corsa, removing the 2 front wheels without undoing the wheel nuts!!! (locking bolt key and key code lost by previous owner), vauxhall wanted £90 sod that, used the hot spanner!!!! (oxy acetylene) and they were off in 2 mins. she was also running a little rough......easy plug in diagnostic tool and hey presto problem identified........you've got to love modern cars lol.

Hi Ralph..Can you create a hotmail email address..They are free..I have some documentation to send to you and ideally it needs viewing on a PC..Cheers..Ziga
Hi zigif you pm me it will come to my phone mate & pc or id you need an email address mate its elitecontract@btconnect.com, i will set up an hotmail acouunt today just incase.
cheers

Here you go mate a how to check your plug leads

i've made it worse yipeee!!! 
well during the week i thought i'd update the earths as the old ones were looking a little tired, so did alternator bracket to coil bracket, AFM bracket to chassis and main battery cable to block, i also fitted new relay and diode to headlamps so now they work (although one squeals like a piggy).
so now i have no spark again, the best i can get is by laying the cable from coil to dizzy cap (king lead) on block and when i turn ignition on i get 1 spark, but nothing while i crank the engine over, just only when i turn ignition off/on!
i measured volts at coil and +ve (12.3volts) and -ve (12volts), when cranking -ve drops to 10volts, the way i understand it is that -ve shorts to earth to generate high voltage inside coil, should i be seeing a lower volt reading on -ve?
has anyone got any clue to what i've screwed up now???? it must be all there because it'll spark when you turn it on but what is breakdown when i crank it over?

If you are getting 12v to the coil then you should be getting healthy sparks from the coil lead to dizzy...If not then it sounds like it could be either a dodgy lead or coil..If you are getting sparks from it when you turn on the ignition and not cranking then it sounds like a wiring issue from the ignition switch or possibly a faulty relay...
Probably need something like this..Although im not 100 percent on the actual wiring but im sure someone else can point you in the right direction..Or check the bottom as im sure they are a female spade terminal fitting that sit in the hole where the relay pins go...Cheers..Ziga

Mine did the same thing after continuely trying to start the engine, coil was completely dead, i proceed to check everthing with a volt meter and ended up disconnecting the ecu and re-connecting and problem fixed, 12v back and car starting, strange, my take on this is your ecu has dry joins mate, if you can get it started, hit the ecu with a screw diver handle mate, mine run alot better for short periods, sounds mad, but it did make a difference, i also found that the ecu plug did not stay put, put a cable tie to hold in place.
You can understand now why i ripped the lot out mate it drove me mad, if you need an ecu mate to play with give me a shout
Good luck
