1987 nissan pathfinder has almost no power.bad relay?

Did you check the fuses thay relay has power at all times when key is on but when starting there are other leads thay have to have power also

i had this problem.got a tune up.which was new distributer,wires,plugs,fuel filter also had a bad feul injector.i think that was all.cost about 400.00

Check for clog converter in exhaust system or muffler the baffle may have come loose in

My 2005 pathfinder was having the same problem. Took it to the dealer and they told me that there was a re-call on a relay that goes to the ECU. They suggested a engine diagnostics. If it turned out to be the relay, the part/labor and diagnostics would be free. My pathfinder is running great now. Hope this helps.

early electronic ignition model i think if my oldtimers memory is correct ,try changing the ignition module ,i think it either under the coil or inside the distributor

Its not unheard of for a pump to go bad that soon, can you hear it run when you turn the ignition to on position, if not chk. fuse and relay and all electrical connections and grounds, If it does run get a fuel pressure guage and chk. the pressure.

Change air temp switch.

FIRST TRY TO SEE IF THE FUSE AND RELAY ARE FUNCTIONING PROPERLY. IF THEY CHECK OUT THEN CHECK FOR SPARK AT EACH ONE OF THE SPARK PLUGS. IF YOU ARE GETTING SPARK THEN I WOULD REPLACE THE CRANKSHAFT POSITION SENSOR. THIS DEVICE IS RESPONSIBLE FOR OPENING INJECTORS AND SPARK PULSE THROUGH THE COMPUTER. HOPE THIS HELPS. PLEASE LET ME KNOW. BEST OF LUCK

Jump start it with + cable on battery - cable hooked to "lift hook" on pass-side of motor. also make sure its in PARK (or Neutral) make sure the "fuse links" (the pink wires from + battery terminal to wiring harness) arent broken or mangled.. if that still doesnt do it, on Pass-Side fender in a little back box (2in wide, 6in long, 6in deep) is a relay (beleve one closest to firewall) called "MAIN RELAY" Common failure on older pathfinders, it just gets old and worn out, replace it, through dealership its EXPENSIVE, through Junk-Yard it may be defective.. I've replaced mine with a cheaper style relay (had to cut/solder wires) ... Discussion Boards on www.4x4parts.com have LOTS of great info on this kind of repair.

could be several things, like bad alternator relay, bad alternator, voltage regulator. have a qualified tech look at it.
