    Camper/shell for the 720s

    Had one a few years ago, tried to sell it, no takers. Tried to give it away, same result. Hated to but finally scrapped it.

    side view mirrors .. looking for something bigger

    I assume your mirrors are attached right to the door. I would scrap those, get some brackets (came factory on some Nissans) then you can attach any mirror you want. The 4x4's had a swivel mount so if you hit something the mirror bracket would just fold over on swivels instead of denting the door or ripping the mirror off.

    Bypass Fuel Pump Relay?

    Installed a new fuel pump relay and it failed within 1000 miles. Don't want to go through all that fuss again. Any reason why I can't take the hot line from the plug and connect it to the power line leading to the fuel pump? I assume pump runs full time but am not sure. Was thinking of installing a hidden switch as an antitheft device. Checked fuse-good. Powered pump from 12 volt source-runs.

    Bypass Fuel Pump Relay?

    Used jumper and pump not running. Pump runs when hooked up to a battery. All fuses good. New relay installed. Test shows 12 volts at pump connection. Pump has been stripped, filter cleaned, reassembled and bench tested before reinstall. All new fuel lines tank to carb.

    Bypass Fuel Pump Relay?

    Pump runs off battery, new relay, tank full. Many years ago my Father taught me if something won't start/run the first thing you check is the fuel. New lines pump to carb and return. According to the idiot test jumpers at relay plug are side by side, right?

    Bypass Fuel Pump Relay?

    OK, new relay installed, checked pump with 12volt source and it works, checked wiring from relay to pump and getting 12 volts, checked fuses all good, still no joy! Jumped relay plug, no action from pump. Hate to tow it to a shop but looking like only option at this point.

    Rear Window: The Solid vs Slider Debate

    I have an old 84 740 (now a parts truck) and the ventilation or security issues never occurred to me. It just seemed to clutter up the clean lines of that part of the cab.

    1980 single cab short bed

    Wood lift should just be acting as spacer. You should be able to remove it and drop it onto the original frame mounts. Pictures a big help in describing situation.

    I think my tranny broke down

    Never checked the oil................ I am at a loss for words.

    squeeling power steering pump

    You didn't define really cold, but oils are thicker and lose viscosity when they get cold. After you drive it for a while does it go back to normal? If so that means the oil has warmed up and the pump is operating normally. Mike, re: fuel pump relay- had a torrential downpour the day I removed the relay and there was a small leak in the windshield directly above the relay. When I took it out smelled of burned wiring. So, a new relay and also windshield gasket. Might as well put in a new windshield too, old one cracked. Any hints as to glass suppliers? All windshield replacement shops in Nanaimo operate through two suppliers, neither of whom have a 1984windshield.

    Correct manual transmission gear oil

    I use 80/90 GearLube. in any gearbox.

    AC Condenser

    AC is horsepower used= poorer gas mileage. I use the 470 method myself. Open 4 windows and drive 70mph.

    Bypass Fuel Pump Relay?

    Using that schematic of wiring plug, for bench test, oil switch power should power pump. accessory power should power pump. power from fuse 5 should power pump. power from alternator should power pump. This should diagnose all circuits in relay. Is that right?

    Bypass Fuel Pump Relay?

    Guess not an issue with me because mine doesn't work but maybe a good idea to check that circuit while I have the passenger seat out to remove fuel pump relay.

    Bypass Fuel Pump Relay?

    Or will just cranking the engine power those wires?

    Bypass Fuel Pump Relay?

    And it may not even be relay. If alternator wire or oil pressure switch wire not powered when running shuts off relay. Can't run truck, so can't test for power.

    Bypass Fuel Pump Relay?

    PS. Mike, haven't seen an early 80's era 720 at a wreckers for years. Salal pickers bought all small import 4x4's up years ago, beat the hell out of them and then bought newer ones when they could afford to. Had 4 in the yard here a few years ago and it appears I should have saved way more parts than I did.

    Bypass Fuel Pump Relay?

    Seems other relay with fuel pump relay is the automatic choke relay. Seriously thinking of relocating pump relay if I have to go in there again.

    Bypass Fuel Pump Relay?

  20. Using stock pump, all wires and connections good. Nothing wrong with the fuel pump, my issue is a brand new fuel pump relay stopped working and you know where that relay is. So, take it out, try to find a way to bench test it, then order another one, and wait?

     

    Solder points can fail but usually caused by years of heating and cooling of passenger compartment and vibration, this one doesn't even have 1000 km on it!

      I am curious as to what brand/manufacturer is the one you have?

       

      I will dig out a used factory one this weekend and test to be sure it is good.  Send me your address and I will send you one.

    Bypass Fuel Pump Relay?

    Been trying to find out why. Proper fuse in circuit, good ground, pump filter cleaned. Any ideas?

    Bypass Fuel Pump Relay?

    Have a box under passenger seat, but not delay lights. If I leave lights on they stay on. Wonder what mine does? Haynes manual not much help. Sounds as though putting in another pump relay is going to be easier than any work around. Is there any way to test old relay before I buy a new one?

    Fuel pump relay under dashboard passenger side, room dimmer simple rheostat on switch.

    Bypass Fuel Pump Relay?

    Checked all fuses today for correct amperage, cleaned terminals and put back in. Just a keep busy thing, didn't get to yanking relay. Will check tomorrow to see if Lectric Gods did something miraculous at now it works. I rather work with hydraulics, at least when they leak you can find it.

    Bypass Fuel Pump Relay?

    See them out there from $35 to $80, so either I buy two cheap ones and cross my fingers or an expensive one and hope it lasts. Saw article on repairing, but that seemed to apply to high mileage units, but will open this one up and have a look. Looked like mostly solder cracks at terminal. Only way I can fit to get relay out is to remove passenger seat, live on Vancouver Island on the Wet Coast and can't get truck into shop for obvious reasons so will work between showers and keep you posted. Crash, you mentioned something about bench testing it- I am a welder and when I play with electricity smoke and flames are normal. Guessing not so much with electrical diagnosis. What would be the procedure to bench test it? And what is that other smaller relay next to it for? Maybe that one blew and affected bigger relay?
