Senator A2.
« on: 14 January 2017, 14:22:19 »

Hello all,
I've just bought a Senator to go with my Royale Coupe.










Needs two new doors but came with 4 good spare doors and a front wing. Apparently the 62000 miles is genuine.
It's mot'd till the end of March.

It does obviously have issues!

The main issue it's missing again on one cylinder-The previous owner suspected a rusty petrol tank-he had it sealed inside and put a new filter and pump on. It ran well for a while then the misfire reappeared.
I've driven it a couple of miles today and am suspecting an injector-theres no smell of unburnt petrol and I'm assuming the injection system is too basic to shut down an individual injector.
I'll find out what cylinder it is in the week and test the feed to the injector-if I find a problem I'll borrow one off my Royale!

Will keep you posted!

Steve

Hi Steve

Nice motor can't beat the big plush velour seats and the nice smooth straight six. I think I mentioned to you in ABS forum about the misfire, just to check the injector securing bolts were tight as I had a similar problem on my old senator causing air leak, buggar of a thing to find but found that one bank of the 10mm bolts were loose/worn. I don't now if someone had them off before and wore out the threads as it wouldn't tighten. Strangely enough it must have been sort of tight as I hadn't touched anything in there to disturb and there wasn't any misfire before, might of been loctited up and wore down over time and loosened off.

Looks tidy :)

The injection system is pretty basic by modern standards, so old skool diags :y

Of the two I had I still wish I hadn't sold the white 2.5 manual to my sisters other half. as he had borrowed my previous black 3.0 auto and managed to stuff the back door in and tear the back of the front passenger seat..

Thanks all,
Came with four good doors (two on the car are rusty) and a spare front wing. All for 600.

Had a fiddle today - the misfire is cylinder 3-plug is dry. Checked voltage at injector got a reading (will check when I bring an oscilloscope home) so suspecting an injector.

The car has had running issues in the past-all to do with rust in the tank-so I'm suspecting a blocked injector?

Anyone got any? (don't want to borrow one off the Royale yet!)

Regards

Steve

Yep-previous owner replaced the filter and pump and had the tank re-sealed. Will get a few injectors (hopefully) and give it a go.

sounds like a seized  or blocked injector I would agree especially if the cars been sitting a while. as far as I know the injectors all fire together rather than sequential so a good spin over with the main coil lead earthed should allow fuel into all the cylinders .showing up the faulty one.have to agree on an earlier reply regarding the interior.fantastic seats/ colour.

Point being that the filter should stop any crud getting to the injectors :-\

Duff injector or loom most likely...

I would also go with a duff injector or wiring loom too, don't think it will have anything to do with the petrol tank...

Easiest thing to do - I reckon - is swap another injector out from the engine and see if the fault follows, if it does then its an injector fault, if it stays on Cylinder 3 it'll be wiring at fault.

Last place I would look would be the petrol tank....

I remember having to repair wiring in my 3.0 one as the windows wouldn't work.

Thanks,
Will swap an injector over and see if the misfire moves with it. Will then send the injector off for a clean.

Thanks
