Right I've converted my 3dr to L8.. Wasted spark anti lag and launch control... Gone to start and it won't fire...everything has been done properly... When I flick the key I get a bang from the wasted spark... Then nothing... Could this be chip related... Has everything is done properly...?

Cheers Mat.

 

when you removed the old coil did you join the wires from iirc the + side of the coil?

 

Yes mate.

 

Any more idea's...?

 

I am sure you woulden't have, but you haven't used your L1 chip have you? (Kind of impossible as well seen as it can run Anti-lag)

Dosen't sound good though with it "Banging".

Martin

 

No mate new chip fitted... When you turn the ignition on it makes a quite bang down the exhaust.. I've got spark and it seems the fuel is there but won't even fire or start.

 

Thought as much, the backfire seems to be a common problem with the WS conversion, do you have the correct TPS and inverted the outer wires?

Martin

 

Yes mate that's all done.

 

CTS connected correctly, and pump priming on ignition? (The answer will almost certainly be yes to the latter due to the fact you say you have fuel)

Martin

 

Did you also remove the capacitor from the old coil wiring, other than that you have got the phase sensor and crank sensor plugs the right way round as well.

 

Yes mate that's all good.


They should all be good mate has they haven't been touched.

 

Are the plugs wet? I would imagine it's just one slight wire etc in part of the conversion that is amiss. Have you gone through it all again?

Martin

 

I will check plugs... Yes have gone through it that's why I'm thinking chip maybe

 

Can the chip be put in the wrong way round?

 

Good point ^^, also have you installed the "WS driver board" correctly?

Martin

 

I've just took plugs out but this could be from trying to start it loads right..?

 

There 071's arn't they, they do look very carbonised!

Do you have any others you could try?

Martin

 

Yes I have some new ones... But these were fine until I tried starting it..

Chips in right way.. And wasted spark-board was fitted at MSD when Wong Rs had it fitted ( I bought the L8 off him)

 

could be sparking at wrong time ?

 

What would cause that mate..?

 

Have you got the extra wires in the correct plug terminals as I think you use different if with or without aircon on L8 as car it came off may have had aircon, just clutching at straws really but hopefully something simple that's got mixed on installation, also does rev counter register while turning over.

 

isnt it running a cam trigger set up is that set up rite ? as you will geta spark an fuel but if its sparking at wrong time wount start is what i ment

 

TPS wires are swapped round for L8 and rev needle Doesn't move.

 

The wires I mean are the 2 extras you put in the ecu plug, make sure they are same as added wires in ecu, also make sure new wires in ecu plug are fully home and making a connection. I am pretty sure rev counter should move a bit when cranking.

 

If you mean the 2 for wasted spark I will check tomorrow but I'm sure there in right mate but will go over it..


Dingla. No it's not on cam trigger mate.

 

i sure i read on a wasted spark thread that you needed to swap the leads round!swap i for 2 and 3 for 4? i might be wrong though or was for there older w/s drivers?

 

I had starting probs once converted to wasted spark, never got to the bottom of it

 

I just need to get it running.

 

When i had this problem it was the wasted spark board.

Are you 100% sure you've soldered the board in correctly?

 

Also what the fuck is going on with your name?

 

Daft question....

Are the lugs still on the bottom pulley Mat?

 

MSD did it and it came from a working car mate.


Fuck knows pal... I got name raped the other night....

 

Yes mate... It's not daft atall mate.. I also thought and checked.

 

Is the ecu definatly working ?

 

This is why I swaying towards chip/EPROM ..?

 

Yea must be mate other wise I would get spark or fuel right..?

 

the additional wasted spark board is not eprom dependant ie you can fit the board to any cossie weber ecu even a standard one with a standard eprom

 

I had problems with mine at first but turned out i had fitted the board wrong, have you got another l8 chip you can plug in ? If it came of a running car and the only theing different is the chip

 

My original board supposedly came from a working car, but was goosed

Quick way to prove everything else is to put the coil back on the car. You only have to desolder 2 wires off the ECU IIRC.

If it starts, that proves the ECU/Chip/sensors etc are fine and its the board at fault.

This is how i fault found mine.

Give me two mins and I'll find out what wires need disconnected.

 

Post #11 on this thread, least that'll help you fault find.
