Hi,
got some serious issues with my motor not wanting to start,
its a 95wrx with a red top engine,
its as if its over fuelling as when it eventually does starts its backfiring and spitting back and generally running like a bag of bolts,
have tried swapping the Maf,
Ecu,
Lambda sensor,
and checked operation of a few other sensors, all seem to be in working order.
new plugs were fitted about 200 miles ago, also the decat pipe was removed at this time.(mot Due)
does anyone know where i can access a ecu wiring diagram??
help appreciated.

Yeah Mate,
Done the diagnostic check but nothing coming up at all,
my mechy is pretty competant, i sctually bought the car from him 3 years ago, pretty much trouble free motoring since, until now that is........
just getting to the stage that we are getting stuck between a rock and a hard place now tho after checking sensor after sensor, i take it the sensors have an operating range? out with this they should show a fault im guessing? is there any failing sensors that wouldnt show on the diagnostic check?
Cheers,
thanks for the ecu link. b13bat

Aye the plug gaps were checked prior to them getting fitted 200ish miles ago,
Not sure if it bump starts as its been in my mechys garage for last 2 weeks.
It all started one afternoon when i went to start it from cold and it didnt want to start, as a mate had Maf issues and his symptoms sounded similar i thought i would try and un plug it to see what like. started no bother, drove 1 mile down the road sand it started back firing, poping as it were over fuelling, pulled over, plugged Maf back in and no difference so managed to drive it a few miles home and it sat for 2 days until the mechy picked it up, He managed to drive it the 2 miles to his garage but only just, and now it bearly starts but when it does its rough as F**k, popping, and backfiring,
Heads done in with it, but in fairness not as much as my mechys..............
Cheers for the input.
