Since last question , did a major recheck of wires change computer . My problem now is that I am getting 12v to the coils and injectors but still no pulse. When engine is the ON position , the ASD relay would activate
when cranking the ASD relay would trigger again so I think that the crank sensor is operating to send the voltage to the relay (fuel pump engages and there is fuel pressure). On the instrument cluster there is no movement on the tach guagel to indicate if there is any RPM .
Any suggestion welcomed :? :? :?

You need to inspect and test the camshaft and crankshaft sensors becuz if the computer don't see this signals it will not complete the injectors ground path. Therefore there's no injection pulse. No fuel

Also no spark
