Was driving down the road and the truck died. Truck starts on starting fluid. Went through and got a brand-new fuel filter, new fuel pump relay, new fuel pressure regulator and new fuel injectors. Fuel gets all the way up to the throttle body. For some reason the injectors won’t work. After all that still won’t fire. I’m not sure what the issue is. Any ideas?

It sounds like you have an ECM that is not working. Also, can you hear the fuel pump in the tank come on when you turn the key? We should also check for codes.

Please go over these guides and send a video back of the engine trying to start so I can see if the engine is any good, please.

Update. I checked the fuses with a test light and found a burnt ECM fuse changed it and it runs like new. Thanks
