Hi guys
I was driving my WRX up a hill on Wednesday & accelerating quite hard when I lost all acceleration.
I attempted to change down gears but there was nothing at the pedal.
I came to a stop & the engine had cut out before stopping & I haven't been able to start it since.
It turns over but just doesn't fire up.
Any suggestions?

 

Lets just go over the basics so we know what to try next

Can you hear the pump prime.
Don't think all coil on plugs would have failed at the same time so check the wiring before it
Is it running an aftermarket alarm

Think thats it for now

 

Fuel delivery. Check pump running and that you actually have fuel in the tank.

 

Checked that the fuel pump primed and it does. Got a full tank of fuel.
Checked ignition related fuses and all OK.
Yes running an aftermarket Sigma alarm.
All wires to the plugs look OK.

 

So it's an ignition issue. Check cam sensor. Then you'll have to check all the wiring, fuses and relays for anything amiss. Immobiliser is very probable.

 

100% petrol and not diesel?

 

100% filled up with V power petrol from Shell. Not had chance to check anything else as of yet 🙁
