No Spark - tried all sorts, need help pls
Hello,
The Scoob won't start.
It's a MY00 UK Turbo, standard apart from fuel pump, decat, newage WRX TM, 3 port and a couple of hours with Bob Rawle working his magic.
I thought it was the starter motor that was knackered a few weeks back so had that refurb'ed. Whilst the TM was off to get at the starter motor I decided to plumb in a catch can and I also put the car on a diet so all the under bonnet air con components came out.
I also started stripping the interior starting at the back and working forward and so far I've got to just behind the front seats.
Finished the catch can, refitted the starter and the TM and now it will not start.
The battery is fine and kept that way by a ctek xs3600 (great bit of kit) it spins the engine over no probs at a decent speed but it will not fire.
Has fuel in the tank
I can hear the fuel pump priming
fuel at engine side of under bonnet filter
starter motor turning engine quickly
changed cam sensor
changed crank sensor (not guaranteed good one tho - off a Leggy in scrappy with big front end damage, still looking for a good one to try)
no spark ( if i take a plug out and earth it then turn try and start it)
not fueling (the plugs are dry if I remove one after trying to start it)
joined green plugs and no fault codes
Please has anybody got any good suggestions, actually I settle for a daft suggestion at the moment.
Thanks Paul

There's fuel in it, and the pump is priming but if I try and start it then spin a plug out the plug is completely dry.
Is it possible to bypass the immobiliser?

Yes its a Sigma if you have a code for it use it it will turn the immobiliser off . If you don't have the code you can reset it and put a new code in then you will be able to turn the it off by the key pad

I have tried the code and it all behaved the same, before code nothing, after code it turns over just doesn't start.

Well it doesn't sound like the immobilizer now at least. Do you now anybody with another ECU you can swap with yours to check it hasn't lost its memory.
No fuel in chambers but at filter= Injectors not firing
No spark = coil pack not getting signal to fire spark
Are the cam and crank sensors you put in from another car are off the same year and UK spec

Do you have exactly the same starting fault as before, or do you now have a different problem since the starter motor was refurb'ed?
The reason I ask this, is that after reading your post, it appears that your car had some sort of problem & you decided that the starter was at fault, so had it reconditioned, but you then go on to say....
If this is the case then you have inadvertantley removed or disturbed something critical that's giving you the same symtoms that a knackered crank sensor would.
Don't worry too much about which engine the sensor came from... They are nearly all the same (Impreza, Legacy & Forester)... The exception to this would be very early engines (1992-1995)... These engines can have sensors fitted that you would not be able to connect to yours.... So, if it fits, it's the correct sensor.

What made you think that your starter motor was Fu**ed??... Was the engine not turning over or was it turning but not firing?

You say "NOW" it won't start... Are you saying that it was possible to start the car before, but now that the starter has been changed & you have removed certain components from the car, that it will no longer attempt to fire up?

Running order -
couldn't start car
remove starter motor and get refurb'ed
remove under bonnet aircon components
start stripping inside
refit starter motor
fit catch can
still won't start.
So, do I have the same fault - to be honest I don't know. All I know for certain is currently it isn't fuelling or sparking, I don't know if it was doing that or not at the stage I removed the starter motor.
The immobiliser seems to be behaving as normal, as you said if it isn't switched I get absolutely nothing.
I haven't been able to try a confirmed good crank sensor yet, the replacement I tried is off a non turbo Leggy that has heavy front end damage
I have had a crank sensor and the inlet harness of a MY99 breaking on here, hopefully that will be with me in a couple of days - first I'll try the crank sensor and if it's not that I'll try switching the loom. I wonder if I have disturbed soemthind whilst removing the aircon or fittin the catch can - that harnes is really quite tight in places.

Hi, yeah the cranksensor was a little grubby but nothing too bad - I have tried giving it a little help with the 'knockometer' as well - still no spark!!

I've checked the fuses and those big see through topped chaps - unfortunately I cannot find any reference to what the big ones are for.
I don't know what the black boxes are, I'm assuming relays of some variety and again don't know what each is for - I haven't checked them.
It's going to the doctors tomorrow, so hopefully Wayne d'man will be able to sort it.
Thanks for your thoughts.

I pretty certain I didn't disconnect anything whilst the TM was off and I was playing starter motor and catch can plumbing. I've checked and rechecked but there could be something underneath that I haven't seen. I got a top harness coming from a MY99 UK that breaking so that may be going on if we're still struggling.
I'll be so pleased when it going again. I'd finally got around to booking a airfield day and it's next Monday so we've got a week - bloody sods law it chooses now to get ill!

Incredibly it only weighs 520kgs with a spare on it and it's a 2.4t capacity tilt bed!
I'll really cheese you off now by telling you I picked it up off ebay for under £1500!

Thanks James - it is a nice bit of kit I have to admit. It's the first time I've used it, not had it long.
