Fuel Pump issues 95 Mastercraft Prostar 190

I have a 95 Mastercraft Prostar 190. Engine would not start, so I went through (had 12V to the pump)and determined the fuel pump needed replacement. I have installed the new pump (IND 495117 FUEL PUMP KIT),and still have to rig up a new bracket to secure this installation. My problem now is that I am not getting a 12 V at the pump. I can bypass and get the pump to run when I wire directly to the positive battery terminal. I have traced the wire to the relay and have replaced the relay near the ECM with no success at starting. Are there any other inline fuses in the wire harness that leads to the pump, or are there suggested trouble shooting steps to find out why there is no power to the pump such as issues with the ECM?

You'll probably just have to do some good old fashion multi-meter work. Follow the wiring from the fuel pump back. Check for power At every single connector and splice. It's getting lost/grounded out somewhere. thats my guess

A bad ignition module can kill both ignition and fuel.....not sure if it's your issue but its not expensive to replace.....worth a look.

Back by the relays there are 2 inline fuses one for the pump one for the ecm they look like little relays just pop the cover off them to access the fuse
