gem Moduler 1999 Ford F350 Super Duty 5.4
Hi guys! 1)My fuel pump was not working so I replaced the pump it did not work!
I checked power running to interria switch I get 7volts! (I connected a battery pack to wire running to fp at interia switch, pump works!) I also have checked all relays and fuses in dash and engine department boxes! I also removed and checked to make sure I was getting power to relays! I did this several times they check out! But, at the fuel pump relay under the dash behind the radio I'am getting no power! ( A side note the flasher relay is in the same little box and it works fine!)
2) Ok now I put 2+2 together see my wind shield has a leak and my radio stays on after key is off and I get the buzzing noise rather my keys are in or not plus no power to the wiper water pump relay so this is clearly the Gem Modular?
I would like to know 3 things!
A) Can any service garage test my Gem or does it have to be a ford dealer?
B) Could no power at my Fuel pump relay be related to my Gem?
C)would you risk buying a used one from a local selvage yard or ebay?
Thank You, Mike
