Ok. connect the scanner to the obd11 connector and get data readings,check the rpm's, if turning the engine over and it does not show any rpm's the crankshaf sensor is defective( or the connector) when this sensor is defective
is no spark, and no fuel pump activation,= check this first= no rpm's? no spark? no fuel pressure?
(replace the crankshaft sensor)
Testimonial: "so if i have it correct there will be no spark if the crankshaf sensor is defective. well there is spark.that was one of the first things we look."
OK,check the fuel pressure, is fuel pressure good? check the signal to the injectors,there is good fuel pressure and injectors signal, check for injectors leak(with the fuel gauge connected to check the fuel pressure,the pressure goes down a soon you turn the ignition off you have injector leaking or regulator)
is car starting when you spray carburator cleaner at the t.b.? check the fuel pump relay,and the MFI relay. (located both at the right kick panel)

GDI Engine Complaints Often Mysterious Hard to Resolve
all i know is that the inlet ports can carbon up
and need to be inspected and de carboned
GDI engine concerns:
Higher cylinder temperatures and pressures released into the crankcase accelerate oil vaporization. Eventually this causes oil droplets to coat intake valves.
Cylinder injector spray position means fresh fuel is not sprayed onto intake valves and flush away vapor build up. This build up can accumulate and bake on intake valves in as little as 10,000 miles (16,000 km).
Rings can become stuck into their lands by carbonized oil sludge. This can prevent these engine’s low-tension rings from properly sealing the piston. This also causes sludge, oil, and fuel deposits to bake onto piston tops.
Since inception, GDI engines have had known problems with coking—buildup of cooked fuel deposits that foul injectors.
