last fall I posted asking questions about a white 2-135 that wasn't getting fuel to injectors but had good flow to the pump through the filter. checked and couldn't hear a click from the electric shutoff but wire has 12 volts power and the coil ohmed out the same as the one on a different tractor. now that it is warm out we proceeded to take the cover off the fuel pump where the coil is and found the coil didn't have enough power to pull the plate back by itself if you helped it, it would hold so then a call to the injection shop and found that the coil is the same in all roosa pumps so we took he coil out of the pump on a dead GMC 5.7 liter in a pickup and bleed the fuel system now it runs again, one word of warning when removing pump cover the bolts can be rusted in to cover and break easily lucky for us it only happened on the dead GMC pump
