Default Turnining over but not starting

Bought a classic Impreza Thursday on the bay and everything was going fine, drove it 140miles back home with no issues got home showed the mrs took my young lad round the block then came back to take the mrs round the block got about 1/2 mile away and the engine died while doing about 30mph in third on a housing estate and now won’t restart
we have taken the plugs out and there is a spark we have also taken the fuel pipe off and there is fuel. At the moment it’s looking very sad just parked up any advice would be grateful
its a 98 classic WRS that came direct from Prodrive with all the goodies on it

Maybe a cam or crank sensor.

It tries to start but doesn’t quite catch to start it enough, the codes have come back with MAFS, Knock sensor and temperature sender. We’ve cleared all the codes and it tries more than before but looks like I need to start replacing these bits one at a time till it runs

Maybe you have flooded it , try bump starting it as the immobiliser seems to work.

Might try a new crank sensor, it looks as though it’s had one recently but as everyone says on here you can’t take it as ok

I would only get a genuine sensor and i wonder if the car has caused a similar problem. PS i would still try a bump start.

Just an observation but surely if a crank or cam sensor is faulty then there wouldn't be any sparkplug sparking..... 🤔

Good point, I’m leaning toward a immobiliser issue as it was running fine then just cut out and as we mess about with the wiring it tries to start a little bit more

If it's turning over you've got spark and fuel its not an immobiliser issue. Check the belt and timing. Plus the three codes you mentioned sound like a wiring problem.

You cleared the codes, did the same ones come back..... fault codes aren't date stamped so you don't know which ones are relevant to your current problem and which ones are historic.

None of the codes have come back, would they come back without it running?

In theory if is a wiring fault as in open circuit yes especially if it's turning over. Check the timing it may of slipped, but if you keep turning it over you may do damage you could possibly have a couple of stripped teeth or a faulty tensioner.

Is it worth risking using Easystart? Especially as it's trying to start.
Are the plugs wet.... where did you check for petrol getting through?... Output of the filter?
(just a few random thoughts....)

Had thought of the easy start, think that’s the next step.we took the outlet pipe off the filter, jet of fuel when the pump primes then squirts after when trying to start, we did notice that nothing was going back down what we think is the return pipe.

No I drove 75miles back up the motorway after I put fuel in it, just checked the receipt to make sure. And I’ve put 3 gallon in since thinking the fuel gauge might be out

If it's the L555 one, then it had a recent cambelt kit fitted (sellers description) so would be not too hard to remove timing cover* to quickly check timing hasn't slipped..... OK, got to remove pulley 1st!, but saying that, IF timing was slightly out, it would/should still fire.... right?
Are plugs wet, indicating that fuel IS getting into cylinders.
*on my MY2000 the cover bolts were badly corroded and difficult to remove.

Good news scooby clinic have sorted it, the problem was the fuel pump was working but not enough pressure, new updated fuel pump fitted and it’s back up and running, they have also fitted a new gearbox speed sensor which was needed and a new knock sensor which came up as a fault, picking it back up tomorrow and hopefully will be at scooby fest a week on Sunday in it🤞
