Default 97 Impreza won't start
Hi all, can't get my 97 Impreza to start. Had to put another engine in, which was a runner in my other scoob. Changed inlet manifold, maff, crank, cam, knock sensors, plugs,leads, coil pack. Getting fuel in cylinders, good spark. Engine turns over well, but refuses to start. Help please as I'm pulling my hair out

Plug leads on correct way round/order ?
Coil pack fitted correct way round and hence correct firing order ?
New inlet manifold gaskets and well sealed (can be tricky to seal sometimes).

Fuel flow may be good, but is pressure ?
If the fuel pressure regulator is knackered it wouldn't be holding pressure and the majority of your good fuel flow will just go back to the tank via the return pipe. You would still end up with wet plugs but the fuel won't be atomising out of the injector to give you the right mixture/burn.

I've had plugs out and got a good spark. Taken out one of the injectors, plenty of fuel in rails.
