Question about 1991 Nissan Pathfinder

1 Answer

My 1991 Nissan pathfinder will not crank.

I can get it to start with starting fluid and I pulled the fuel hose loose and it is getting gas to the line going to the injectors but will not crank. I am thinking maybe the injectors are not firing but I do not know how to test that.

You would unplug the injectors and check for voltage on one side of the plug and a ground pulse from the computer on the other. All 6 injectors should have battery voltage with the key on, and then the computer grounds the injectors when they are supposed to open.

    We use a node light or a low voltage test light to check injector circuits. The light is supposed to flash when the injector is supposed to open.

Sounds like either the fuel pressure regulator or a clogged fuel filter.

SOURCE: Cranking but doesnt start, or intermittently not starting

My car does the same thing...sometimes it wont start....have to turn the key off then when I crank it again it fires right away. Possible that the in tank fuel pump pressure regulator isn't building to the proper pressure. Nissan did post a recall....under warranty *recall* I might add.... there is an updated pump that will cure the problem but since you most likely are out of warranty it will cast $400+ for the part plus labour if you can't install it yourself. Call nissan to verify if your car is affected by referencing your VIN with them. Dave.

Broken timing belt damage engine 93


You mean it will crank but not start ? Do you have normal compression, spark and fuel pressure ?
If the timing belt broke you won't have compression on all cylinders.

in order for an engine to run, you need compression, fuel, and spark. you are probably missing one of these 3. remove your air tube from the air filter box .eand spray starting fluid, or brake cleaner into the throttle body. if it starts, you pave a fuel problem. i e fuel pump of pump control

I have a 99 nissan pathfinder that won't start, it has spark and fuel. I even sprayed starting fluid and still won't start, replaced the distributor, same problem. does the crank sensor has to do...


well it takes four things for an engine to start,air, fuel ,ignition and proper timing of ignition and valvetrain . if you have spark then i presume the cams are turning , fuel injection is control by the ecm based on crank and cam inputs ( if applicable been awhile since seen a 99 nissan )
if you have spark then can assume the ecm is getting a crank sensor pulse , that leaves valve timing . any codes? check light on ?
did it die suddenly or just not start one day ? i would be app to check timing belt first make sure its lined up correctly . even if fuel injs were inop it should still start on staring fluid indicating a fuel problem, i would do a compression check also if the belt jumped it may have bent some valves if its interference engine but i dont remember, and make sure its getting air through the air intake

Hi I am working on a 1991 nissan pathfinder and it is not getting any gas. I put a new fuel pump and a new fuel filter and changed the fuel pump relay, But still no gas. you can hear the pump kick on. and...


Disconnect ( or at least loosen) the fuel line as close to the engine fuel delivery system as you can and see if there is fuel pressure. You may have a vapour lock. If you do get pressure how much ? Is it sufficient to supply your requirements. A "new fuel pump" does not always mean a "good fuel pump" - from experience!!! If you do not have fuel at the engine work back to each fuel line connection to were there is fuel pressure if at all. I am not a Nissan expert but the principles are the same for all. You do not say if it is fuel injected or carburated. FI requires higher pressures than carbs. Hope this helps. Let me know how you do in your efforts. Thanks Good luck.

1999 Pathfinder shuts off while running.


It could be one or all of 4 sensors. the MAF, the MAP or the idle position sensor or dirty fuel injectors. the fuel injectors can be cleaned with an over the counter fuel injector cleaner bottle that you pour in your tank.If these do not fix it, it will be the EGR valve or a vacuum leak to the EGR. Check the fuel injectors first by buying the cleaning product. then check for vacuum leaks around the Fuel injector housing. Buying some starting fluid and spraying it over the small hoses while the car is running will make the engine stall when the fumes from the starting fluid get into the system. then have it scanned again to more or less tell which sensor it is. it could very well work with the fuel injector cleaner.
