hello,
well as the title says, i have a check light on my evo 7 saying abnormal fuel system.
has anyone here had this problem ?

did a bit of reading and found that these are the possible causes.

Failed fuel supply system
Failed oxygen sensor (front)
Failed intake air temperature sensor
Failed engine coolant temperature sensor
Failed manifold absolute pressure sensor
Air drawn in from inlet hose and inlet manifold
Exhaust leak from exhaust manifold
Contamination of throttle body (throttle valve portion)
Failed injector
Failed purge control solenoid valve
Failed fuel pressure
Failed engine-ECU

also can someone direct me where to locate the intake temp sensor, engine coolant temp sensor, manifold absolute sensor.


thanks and sorry for sounding like a noob.

Does it run? and If so what does it run like? I've got a document that shows all the sensor locations on the car I can email you if you PM me your add.
Finally has the car been modified and if so what has been done?

Sent you an email mate,
What kind of diagnostics do you have? With evo scan you can log your fuel trim, MAP etc etc. Might be worth getting that. Other than that how long have you had the boost controller in? If it was recent that could be the culprit
