My corvette will randomly intermittently not start. The engine cranks as normal but acts as if it is not getting fuel. While I did not have the proper fitting to put a pressure gauge on the fuel rail shraeder valve, when I dpressed the stem it was obvious that the fuel pressure was very low and no where near 46 PSI. Also while driving I will randomly and intermittently get the following warnings: On the display panel sometimes the "Service ASR" light will illuminate. Again at random times and under no specific circumstances. Also on the speedometer display where the fuel information is normally displayed the fuel info will go away and the word "SYS" flashes 3 times and then the display returns to the fuel display. Co-incident with the flashinf of "SYS" the "Security" light in the lower left corner of the dashboard flashes on 3 times and then extinguishes. The following actions have already been taken: Replaced plugs, wires, distributor, fuel pump, fuel pump relay, fuel filter. Other indicators; The problem of not starting appears to happen more often in hot wheather, it also appears to happen more often when the car is parked on an incline (front end higher). I am thinking that maybe it is an ECM problem ?
