check your fuel pump relay and also check for codes -
Answer 2
Have a mechanic check fuel pressure to see if it bleeds off quickly when engine is switched off. Verry possible you have a "fuel spider" (injector) problem. -

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
