It appears that I have intermittent power feed to the electric fuel pump in the back of the car. I have a factory wiring diagram that shows a white-with-purple wire feeding power to the pump. This seems to come off a (possibly in-line) fuse labeled "No4" which, in turn is fed by a white wire that comes off a junction that also feeds power via white wires to the ignition coil, the ignition warning light, and elsewhere. According to the schematic, this white wire comes off a fuse labeled "N96" with the "9" being in superscript.

Can someone please help me figure out just where these fuses and wires are so I can troubleshoot this? I am aware that there are several fuse blocks behind the small instrument panel, and I have accessed and checked those fuses, but these fuses don't seem to be labeled the same as those described above.

I have no other electrical malfunctions, although I do have a spare bottle of Lucas Wiring Harness Smoke on hand just in case... ;-)

Any help will be greatly appreciated.

Thanks much,

Dick

George, once again I am indebted to you for your sage and helpful advice. I was able to locate and clean the bullet connector under the right side of the dash -- the white wire that feeds the fuel pump. Turns out that, even with proper power, my (aftermerket) fuel pump was inop. I replaced it with another aftermarket (sorry...) pump, made sure I got a low pressure pump (2.5-3 psi...), reconnected everything, and now she's running like the proper kitty she is.

Thank you for sharing your wisdom with me and others.

Kind regards,

Dick

Dick all of those fuses are in a neat little compartment behind the center panel--the one with thumb screws. Drop it down and you will find a metal plate that will direct your efforts. I think your problem is you are not using a factory wire chart. You should be looking at wire chart W5495.36.42. You will find you have a white wire with one bullet connection (you will find that on the RH A post under the glove box and toward the door. The white wire goes directly to fuse #6 which does have a "bridge" wire or "jumper" if you prefer to fuse #7. Your fuse #N96 is a mystery. If your car has been modified please save your can of smoke and get it to an automotive electricial--the older the better.
Once again as soon as you open the center panel there will be a metal plate that describes the function of each fuse and their number! Good luck.
