Electrical problem please help
Hello again, 1995 wrx import, a couple of times she has not started on me just won't fire but leave a while and normally goes, we'll this time it seems whatever it is has totally gone now as she just won't go, I had rac out the other day not much help but what I did find out is that I have no injector pulse, would crank/cam sensor failure or lamba sensor or any other sensor failure stop injector pulse or should I be looking more at alarm imoberliser which is the sigma, or would there be any common reason for something to intermittenly brake down then go??? Any advice more than welcome I'm lost when it comes to electrics, thank you

The only mods I have at the moment is dump valve, turbo timer, td05 turbo but I believe they come as standard on the early imports with the closed deck engine, an apexi filter and full system including headers, hks high flow oil filter, and silicon hoses that's about everything, I'm wanting to modifie but I think I brought a bit of a bad one and have done nothing but try and make it a good car first,
I had water pump and of course cam belt go withing 3 weeks of owning her, I done all that with second hand heads but new multi layer steel head caskets new pulleys tensioner, pump, belt etc then I done power steering, then wheel bearings and brakes brought the high level Sti spoiler but a bad copy which I'm still trying to shape and make looke nice, and now it won't even start,
Starting to get down hearted with the whole scooby thing but I'm still trying to tell myself that it will be good in the end with all the new parts she's getting cheers guys

Your gonna need to find those wires and check for codes. Get down by he pedals then look up under the steering column. You should see the 2 green plugs and 2 black plugs hanging together. If you can see them put your hand up and have a feel around. I've seen them taped back up in the harness sometimes but they should be there.
When you turn the ignition on, can you hear the fuel pump priming from the boot area?
Could well be crankshaft sensor, but could also be lots of other things. When you get it running, does it run ok?

And yeah when it was running it was running sweet, ah well two small issues, 1 sometimes I thought I wasn't getting full boost when going through the gears, lets say just on odd occasion I'd go through second with little boost then it would hit hard again in third?? And no2 again only sometimes you will floor it and it would sound like there was an air leak like a dump valve noise and them once that noise went you would then get boost, I replaced all vacuum pipes with silicon and new turbo inlet with blank off bung, I thought this might be something to do with dump valve maybe fluttering about then all of a sudden getting sucked shut so then getting boost when shut?
I will hunt these plugs, I take it there only small plugs as I found two black and one green together so maybe the other is tucked up

Sounds like a sticking dump valve to me.
Yes, they are only small. Sounds like you have found them.
Keep ignition off.
Plug 2 black plugs together
Ignition on
Watch the Check Engine light flash.
It flashes morse code. LONNNNG flash =10. QUICK flash =1
Write down the number/numbers and then post on here or search online for corresponding fault code.

Ok I will be looking for a stock dump valve now then this one was on it when I brought the car,
Can my stock ecu be tweaked ok, and do you have any idea what sort of money I'm looking at for a tweak by jgm just so I make sure I have enough cash waiting for him and don't make a fool of myself,
