New fuel pump and still has no power to fuel pump or rails.

Recommended Posts

So my 98 dodge ram 1500 quit on me going down the interstate the other day. Checked my pressure at my fuel rail and it was at 31 so figured it was about time to do a fuel pump so put new one in and now it wont kick on. Thought it was a relay so got a new one still nothing. So I had some new injectors so went ahead and put those on and still I have no power going to my new fuel pump. Could it be my ECU went out or what someone please help. Oh and my fuel gauge isn't even moving when I turn on the truck.

In a gas powered truck the PCM controls the fuel pump relay, injectors, and ignition along with a host of other things. 

You'll need to do some testing to find the problem.  Start with the basics. 

Is there power to the fuel pump relay at pin #30 and #86, is the relay being grounded when the starter is engaged.

Is there power to the injectors and do they pulse when the starter is engaged. You will need a node for this test.

Is there spark at the sparkplugs.
