No start. Turns over. Fresh battery, alternator, PCM. (ECU). Running great after new computer. Sudden quit while leaving driveway. Still cranks but no start. Replaced crankshaft sensor on advice.-Still cranking but no start. Could camshaft sensor be issue. Reset ecu? Checked all fuses and relays. And fuel pump is working. Confirmed many things are still working. Car was awesome after new ECU, but next day it did suddenly shut off.

Hi,

Are you getting proper fuel pressure? Have you confirmed there is no spark? It is possible that you got a bad ECM, but it could be other things as well.
