If there is no spark, then the cam position sensor is probably at fault.

If there is no fuel pressure, check the schrader valve at the end of the fuel rail with a cloth and phillips screwdiver to push the valve. If it just dribbles out after an attempted start, then the fuel pump might be toast.

Is this a new 103 relay? If not, jumper the slots for 15 and 87.
