Hello!
Been working with my mate on his HB SC 306 and we can't get the thing started now. After rectifying some awful wiring extensions which were carried out by the previous owner for the SC conversion I thought we'd cracked it. But still no joy.

After trying another crank sensor and poking around with a multi meter we are only getting power at one coil pack!

Anyone else had this. Tried another fuel pump relay already.

Thanks Ash

Yes to all. Have even looped out the relay out the system to try.

Have a spare ecu to try?

Nothing to see here

power to the coils are from the same feed on the relay, theres a splice or two in the loom.

Bring on the Trumpets.

Not all of richs ecu were unlocked. That was only done at the customers request i believe.
The lbsc car i bought had a locked ecu, had to send it back to rich to get it unlocked to be able to use it on my car.

have you 12v at each coil pack? measured to ground?
as welshpug says they are common fed from the relay with the ecu switching the ground sink

so check the wiring.

Haven't stripped it all back but it looks all ok. Could an ecu give these symptoms?

Right, after more head scratching and hours spent getting nowhere the car still wont start..

We have looped out the red switch on the bulkhead, stripped back the injector loom, cut out the joiner where the single wire splits into four and remade it incase this had failed. We are getting 9.5v on the single white incoming wire and getting 9.5v to each coilpack on the plugs.

However we have only got a spark physically coming out of one coilpack. Next logical thought was maybe somehow three coil packs have gone down (probably more chance winning the lottery) however we tried each coil pack on the plug which was actually giving us a spark and every coil pack worked so that ruled out coils
I think the spark we are getting from one coil isnt as strong as it should be either.

What voltage should we actually be getting at the plugs? My only thought at the moment is we arent getting enough voltage down to the coils and it is just about giving us a spark out of one plug with the least resistance?

Im at a loss currently!

Im sure you should be getting closer to 12v at the plugs you have a volt drop somewhere on the line somewhere you have an increased resistance at a guess

Or s**tty battery

Is it trying to turn over or just clicking and nothing

Also do you have lights dash etc

Try changing the coil pack that appears to be working ??

Should be well over 12v on a new battery - about 12.6-13v depending what it is. 12v is flat.
