Car is out from the cover of my shed while I do renovation work on my house to sell it,been tucked away under car covers @ the rear of my house ,went to move it to other undercover storage and the fuel pump was a no go,checked relay,replaced earth lead which was a bit dodgy,fuse on my rebuilt relay board is ok,a bit lost on this as the pump has only done low hours.
Anyone had one fail ? or other suggestions what to look for before I proceed further but I have little time for this (IMG:style_emoticons/default/sad.gif) . |

Your ignition switch may be ending its career.

Your ignition switch may be ending its career. Hi yeah know the issue with the switches,one I have is near new (done 500kms ),more tests showed power direct to pump with a battery and it works,supply wire has continuity to pin 13 on 14pin relay board connector so that's a good start, appears to have power with key on to fuel pump fuse (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) . Stuffed around with various other things one being a relay change and bingo won a price ,pump worked,appears the large amount of spare relays supplied by PO are suspect (IMG:style_emoticons/default/slap.gif) (IMG:style_emoticons/default/slap.gif) . My whole electrical system has gremlins everywhere which pisses me off however now I can move the car to undercover storage. Thanks to all that provided tips and feel like a dick cause I should know better but dealing with 40+yr old parts is a crapshoot afterall. |

Update Well my fix hasn't worked,boxed up gravel guard over pump lowered the car back down ,added fresh fuel tried to start but pump not working again (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) ,I had previously checked it many times yesterday and worked first time every time,pulled the relay board and found the positive on the pump fuse a little melted and loose ,I thinks there is a poor contact in side of the board. My plan is to transpose pins 11 and 13 on the 14 pin plug and run off the heater boost fan /rear heated window circuit with smaller fuse for my fuel pump...should work ok (IMG:style_emoticons/default/confused24.gif) . |
