Buy a NOID light kit to confirm that the injectors are not being actuated. Also perform a fuel pressure test for obvious reasons. If theres no power then check the injector fuse/relay. If it checks out, then youre just going to have to start from the injectors and work backward, checking for power and ground until you find the issue.

Thank You will try.

fuel injectors and fuel pump r powered through fuel pump relay from the fuel pump/ijector 20a fuse do you hear the fuel pump kick on ? if no check fuse and power through fuse if good move to relay if all injectors will not work it could be the fuel pump causing the fuse to blow which is causing no power to the injectors hence injectors not firing if fuse is blown u can disconnect pump connector and put new fuse in of the same rating and see if u get ur pulse back if id say it is a fuel pump hope this helps good luck
