Right, i'm ok with everything until it comes to electrics and then i only know the basics!

Amplifier
ECU??


anyone?

had the same issue with the white tub dunc, the ecus are the last thing i'd look at, pete and i worked back from the spark plugs to the coil, and it was def the coil that went, having said that your tubs a bit diff....monster hybrid frankenstien lump up front....

cheers jai, didnt realise u had the same prob!

lol, as you put it, i have a 'monster hybrid frankenstien lump up front' but my coil etc is all standard goodies and used to run fine on it! im now now getting a spark since i fitted my new fuel tank and had the box rebuilt! checked everything and all is plugged in etc

on the mk2, you have a Amplifier as well as the coil its self. the leads are perfect so no problem there, i'm changing the coil and going to do the amplifier too. after that im stuck?

never reaally looked at my cogbox but are there any sensors attached to it a crankshaft sensor? they need an air gap and can cause problems. dunno if it has one though???

...had the box rebuilt!

Don't mean to ask the obvious but...

Are you sure the earth strap was replaced

 

[jamie86]

Yeah was gonna suggest the same thing, check the earths are deffo ok obviously touching metal and no paint etc in the way

Schoolboy stuff I know but I had that once

 

[Dunc Uno Turbo]

louie, you mean the earth that bolts to the box? i put that back on. hmmm, cant think what the earth strap looks like and cant picture my UT ever having one ??

[jamie86]

I've found they tend to have an earth for the block as well but again not sure on an Uno..

Just get a bit of battery cable and find a suitable bolt on the block and try it...

 

[Chas Uno]

Dunc, get a multimeter and check that there is actually power getting to the coil!

Have you also checked the crank sensor as I'm sure a UT has one?

 

[Dunc Uno Turbo]

all crank sensors are fine, also, the coil is now good as ive changed it, and the coil amplifier is fine all been checked. ive got a couple of extra earths on my UT anyway from the block etc so the cars well earthed!

hmmmmmmmmm

After you've done that coil and amplifier:
Without the pickup from the tdc / crank sensor you won't get a spark because mr.ecu wont know when to fire!
Get something like a test light (fast reaction) or one of them fancy occiliscope things out and bang that onto your crank sensor while cranking - see what its doing..

Good day,
Hope you guys can help me out.
Im at loss. I have an Uno Turbo 1400.
New engine. New T28 drift spec turbo. Intercooler, copper button clutch etc... Car was idling, switched it off and after a while wanted to start it but there is no spark. New coil installed, still nothing. There is power and earth to the coil. Timing is set up 100% but there is no spark on any of the leads from the coil. Tried 3 different coils and still nothing.. Any help or suggestions where to check next?

 

[MrTurbo]

I can't see any crank sensor. Where is sensor situated? Pls try post a pic of it so that I can go check
