[s-cars] Mysterious fuel pump problem at start

[Mark Strangways]

I have found hard starting can also be from the check valve at the FP, it 
will bleed back all pressure to the tank.

The ecu controls the FP, and it assumes there is enough pressure to start 
the engine.
When I had the problem, I would have to go WOT and crank it for a while till 
the ECU decided to start the FP.
