YEE HAA!!!
Well done dude. You toughed it out!
At least now you know the wiring is pretty much right!

So, what was the issue??

main reason was where i had the pink (ign) hooked up to it was recieaving 0 volts when cranking, the ecu needs 10 volts to work while cranking so i went straight to the batt just to confirm.
now its clean up time of the car. theres wire everywhere and hose clamps not done up etc etc. maybe off to the tuners thurs,friday :lol: :lol: :lol:
depends if my BOV turns up today. but yer just a little to go now

I had a vacuum hose which i forgot to tidy up and made me spend an hour buggerising with the tune of the computer... I realised the following day the boost guage was not connected but the line already had the T fitting on :oops:

nope i think its def a timing thing, either spark, maybe fouled plugs or me punching buttons in program mode on the handsetbefore i knew what i was doing :oops: . i have ran the car without the vacum on before with the stock setup.
this sounds completely different. like a vw. it's very hard to start aswell. how important is it to have the timing at 10 degrees bdtc. i dont know how to get it to 10 when i can only just start it and i cant idle the car. i cant remember what my timing was at when it last ran? it would be around the 12-13 mark i think. any idea's?

im not looking to do a full tune i just want it running or at least idleing properly when i take it to the tuners so it doesnt cost me more money at the tuners for them to fix.

jules, i will throw a few up toninte....promise

well when i first started this project i thought how hard could it be....it was going along nicley till i hit the ecu. my advice here if you have little knowledge of electrics like myself buy a plug and play. it would have made this process alot easier. once you have clicked on da pic you can click it again and it will go bigger again etc etc :)

the sad sad site, dust everywhere

Well at least you have a TV to look at :mrgreen:
You might want to change that battery soon. It's not very MX-5 friendly.

5s are supposed to run a special vented battery that connects to tubes that vent battery gas outside the boot. You can also substitute sealed batteries like the Odessy ones, or as I have just done, one of the new Supercharge Calcium sealed batteries @$99. Basically you don't want a battery that can leak acid or fumes in your boot, and you should secure it firmly too :)

Are you firing in wasted spark? ie two cyl fire at once, like 1 & 4 but only 1 cyl is on the compression stroke and therefore may be out of sync? Sean correct me if im wrong, but if you are out of phase even 180 degrees the engine will run, but it will be a pig...

What i mean is... you may have injector no 1 firing on the compression stroke, but the spark is arriving late/early and the mixture is not at is required firing stage. I suggest you get someone to look at what the computer is doing whilst you turn the engine over (if the hand controller allows for live telemetry)...
Huh?

yep, it's the worst i have ever heard a motor run..... so much so i dont really like running it until i know how to fix. i was just hoping to get it idleing so the tuner can get into it without having to muckaround just getting it to run. will see what happens :)

one thing is for sure though you guys have been a tremendous help

But the throws on cyl 1+4 and 2+3 are the same anyway....

So even if teh injectors were wired 1234 instead of 4321 that shouldn't matter.

I suspect it's a combo deal of fouled plugs (from not starting but having fuel pumped in), an engine that's been sitting unstarted for a while, and a poor basic tune.
When results speak for themselves - don't interrupt.

oh ok... I thought he may have had it firing sequentially and the petrol getting in on the wrong stroke of the crank/cam...

ie: cyl1 compression but cyl 4 has had the injector squirt fuel on the wasted rev so cyl 1 spark will be igniting an empty chamber and cyl 4 spark firing a mixtire not compressed properly because of the valve overlap.

Did i explain that properly :?:

Oh well something like that :? :)
Huh?
