Rv 7.4l 454 on a p30 chassis. Yesterday I replaced my water pump, when I got it all put back together I went to start it and with the key in the on position the dash turned on and all accessories. But when I try to start it nothing happens have a good bat good alternator, good starter. But if I jump the solenoid across with the key in the on position it will fire up and run fine.
