Getting spark but no fuel.. need help
ok my dad has a 95 ram 1500 and he told me he needed a new fuel pump put in. The engine would crank but wouldn't fire if u spray starting fluid it will run for a second that's it. So without even troubleshooting if that was the problem I replaced pump and it still won't fire. Has spark, and there's no fuel pressure at the rails. Put a test light at the fuel pump fuse and fuel relay was good. I also put a test light at the green/ black wire at pump with key on and showed no power also tested same wire but right after it comes out from under the fuse panel under hood and it also showed no power going to it. And now from here I'm lost I don't know where to look next. I thought I read if crank sensor is bad it will tell computer not to send fuel but I thought I'd come here and ask before I start throwing parts on it. Thanks

Fuel pump gets its power via the relay in the PDC, if the relay doesn't send it power, the fuel pump doesn't run, therefore, the engine doesn't run. If you don't hear the pump priming, you have either a pump problem, or a power problem. Verify if you get power back to the pump. (again, only for three seconds when you first turn the key on.) Take it from there.
