75, 2.0, djet. Won't fire. Spark is good. A little starting fluid in the intake and it fires. Clearly a fuel problem. I'm not hearing the fuel pump. Shouldn't I hear it for a few seconds when first turning ignition on? I checked the fuse (#25 on the relay board) and it's good. I'll put a multimeter on the pump terminals to check for power next, but thought I'd throw this out there to the collective for any other input until I can get back to it. Grounds are also on the list. Or put power directly to the pump and see if it runs.

First I would like to thank all the military people for their service. On weekends like this when we get busy it is so easy to take what we have in this country for granted.
Today I had a few ideas on things to check out as to why my fuel pump does not run. I was looking for continuity for the ground wire at the pump. Well as my photo shows the ground wire has come loose from its' post. That will be an easy fix, and the wire may have giggled loose when I first unbolted the pump during troubleshooting. I then thought I would check the continuity of the hot wire from the 14 socket plug to the positive pump terminal. Well as can be seen in my photo that plug is cracked and the plug for fuel pump power is loose. I suspect the previous owner broke it but managed to get it to make good contact. I had taken off the plug from the relay board to spray everything with contact cleaner during my initial repair work. This may have been the start of my GOOSE CHASE. I am not 100 % certain how best to repair the plug but I certainly will be able to sleep soundly tonight knowing I now have discovered the root cause of the problem. Any suggestions from this board will be appreciated. Before going into the house I decided once again to check the "bad relay" I uncovered following one of the trouble shooting guidelines. Well today it worked using the headlight as a test bed. I will put that one away for I do not want to play Russian Roulette. I do have a question about sealing the relay. There are many spots of the black sealer that have fallen off. What is the best to reseal these spots, RTV, Silicon or latex calk, or Flex Seal (as seen on TV ) ? Attached thumbnail(s) |
