Bit of a prob

[BROOMY]

Started to tighten my exhaust manifold.
Which ment removing the HT leads etc and I swear I put them back right .
Now it won't start?
Sounds like it has a killswitch somewhere but never before.
What could it be?

[HairyScreech]

Did you disturb the king lead?

[BROOMY]

What's that?

[pacerpete]

I reckon it's your alarm ........

[BROOMY]

That shit don't work.

[BROOMY]

Am I ment to put a lead on first?
I unplugged the 2 things below the HT leads that plug into the coil pack I'm sure I put them back how they came off .
Would that cause it not to run?

[BROOMY]

Tomorrow I'll just unplug the alarm then all sorted.

[Speedtouch]

Which engine do you have? I would imagine that the coil pack is polarised, so quite important to fit the LT leads the correct way round.

[BROOMY]

M42. I fitted the leads correctly as they were numbered.
All ran before just needed the manifold doing up.

[BROOMY]

If you don't fit the ht leads the right way round , what will happen ?

[Speedtouch]

It will usually run, but roughly, as if it's out of balance.

[BROOMY]

But this has a coil pack not a distributor.
So should run fine shouldn't it.

[Speedtouch]

Yes, but unless the firing order is correct, it won't run properly.

Try removing an HT lead, fit a spare spark plug into it and rest the plug on a metal (earthed) part of the engine, then crank it over and check if it sparks.

[BROOMY]

Yes they all spark that's where I'm stumped and all getting fuel.
But doesn't wanna run even Though it has original ht leads with the numbers printed on them.

[Speedtouch]

In that case, perhaps you've flooded it? May be worth leaving it for a few hours, perhaps with the spark plugs removed.

Alternatively, crank the engine over while spraying carb or brake cleaner down the throttle body.

[BROOMY]

Ok tomorrow I'll try that.
Going cinema later and I'm not at home right now.

[pacerpete]

M42. I fitted the leads correctly as they were numbered.
All ran before just needed the manifold doing up.

M42 you say ? Now it is all starting to make sense......

[BROOMY]

Something I missed?

[BROOMY]

I feel stupid but the plugs were soaked.
On any of my bikes this never happened but maybe coz my bikes were carbed.

[Speedtouch]

So you managed to get it started?

[BROOMY]

Yes.

[Speedtouch]

Good to hear that.

[BROOMY]

Tightened a stud and it came out.
So tomorrow get some lock tite n bang it back in there .

[Brianmoooore]

Studs aren't held in by Loctite, they're held in by threads - things which I think you'll find are missing in your head behind this particular stud.

[BROOMY]

Didn't just come out was loose undone by hand so that's why I plan on redoing it tomorrow .

[Speedtouch]

You'll probably need more than plain Loctite - try thread lock.

[BROOMY]

How deep are the threads in the head from the exhaust ?
Are the exhaust ment to have a spacer sort of thing?( a silver plate thing) not the gasket , it's thicker than that

[BROOMY]

What about if the threads are stripped what should I do?
Bit awarded to helicoil it as it's on a freshly fitted head I believe.

[Speedtouch]

You could try using a tap & die set to re-cut the thread, or you may have to drill it out and re-tap it to the next size up.

[BROOMY]

I'll hope for the best tomorrow and report back.

[BROOMY]

It doesn't seem to run again .
Plugs are dry fuel pump doesn't click need help

[Speedtouch]

Sounds like it could be a duff crank position sensor, or the fuse to the ECU/fuel pump has blown.

[BROOMY]

But wouldn't a diff crank sensor not allot it to spark aswell as the engine not knowing its position

[Brianmoooore]

You haven't said whether you have sparks or not.

[BROOMY]

Oh sorry yes I do.
