Evo 8 non starting but turning over

[jimdon]

recently broke down on M1 serpentine belt fraid, have replaced but now car turning over but wont start occasionally makes a pop, diagnostics showing P0090 (fuel regulator) but not connected to serpentine belt so should not have packed up due to belt been fraid or vice verse belt would not have fraid by regulator packing up fuel is getting through as disconnected pipes and checked, any ideas or possible solutions

Hi,
possibly when serpentine belt frayed some of it went inside the T.belt and make timing jump.I would check timing first.
Thanks

Not much interest ...
If you check out the to wires that cross from the back of the engine at the front of the cam cover, they go under the black plastic coil pack/plug cover, they go down the side of the engine, one goes all the way down to the bottom of the engine, this is the wire for the crank sensor, it could have been damaged by the serpentine belt, it goes close by round the Aircon and pump.
Also flash out the fault code, this should tell you what is wrong.
Good luck

Both good answers both need checking
