Check fuel filter sounds is all thr lights on when it cuts out if so id be looking into the fuel. If thr lights are dying then check alt id start out thought looking into relay for the fuel

1987 Nissan Stanza

you will need a repair manual
http://www.nicoclub.com/service-manual?fsm=Stanza/Sanza_1989_FSM

comes up as having both efi or carby what has yours got

if carby its a lot easier to bypass the faults to get it to run

will assume its EFI

EFI will be a problem if any wires have shorted
may have blow the large fuses in the engine bay giving power to the car


for both carby and EFI
pull the light fuses and relays out

check all fuses and relays in the engine bay cluster are not popped

starter relay and EFI ecu fuse are in the engine bay cluster

if the motor turns over
the fuel pump must be pumping fuel with pressure required to run the car to get fuel to the carby /or fuel rail and injectors
if you get that
only have to worry about spark
have you got a good coil arc and spark to all plugs

Nissan recommends only NGK ZFR5E-11 spark plugs for your 1991 Stanza and they already come pre-gapped in the box. They might cost a little more than bargain brand spark plugs, but your stanza will definitely run much better with OEM plugs.

could just need a tune up,you could also pull of the distributor cap and look for oil intrusion, if there is you will need to replace the distributor

I dont know if this may help or not but 87-91 jeeps had bulhead and wiring problems at the firewall area,
also had distributor and computer problems. relays were also a problem with tese vehicles. Good luck with your problem

if your citalitic converter is plugged the car can,t get rid of exhaust and may not be able to run much above idle.

pull distributor vap and make sure the distributor is turning with that many miles my guess is the distributor drive.

First disconnect the positive battery cable! I released the pressure by pulling off the top gas line at the fuel filter under the hood. (carefull of getting fuel in your face). The fuel pump is under the backseat.

here is a picture, it is on the outside of the distributor.

Check distributor and fuel, when car dies check for what is missing when it won't start back up. It can be only gas or spark and trust me one is missing. Good Luck
