Question about 1989 Nissan Hardbody King

1 Answer

Fuel pump 1989 4x4 with z engine 2.4L. Title says made in USA but the fuel pump that I took out looks like one for a Japanese built. The specs show that they have different PSI. My truck has Throttle body fuel injection. I hate to spend $200 for the wrong pump. Any help?

With a vehicle that old I think you should retrofit any pump that matches within reason the original specs as with throttle body injection fuel pressure is critical. If it is the same as South Africa the agent will sell you any **** to get rid of you. Try fitting a Bosch pump with a pressure regulator (set it to spec ). Please change the filter.

Need for a 1993 izuzu pickup thats not getting gas to carberator

what engine? there are like 7 world wide. is car USA
the word PICKUP is both generic and real trade mark. how do you mean that word, USA pickup 93? or some other pickup sold world wide, looks like pickup but has other names (vast)_
ill guess USA, 2.3-liter 4ZD1,
outside usa its a FASTER (and huge list of names)
the usa engine sure did have a CARB, last one was 1994 in usa,
and Isuzu made that car... ending carbs forever.

how do you know that? (NOT GETTING FUEL)
no method stated.
looking down air horn cranked (boom , eye browse burned)
or cracking lines looking at dribble.?
or see the High speed accelerator pump dead, in carb. horn viewed?
CARB 101 (basic basics)
one isuzu with carb has glass float bowl lid (yah scary) does yours>?
1: fuel pressure at spec, 3.5 PSI is spec, (off SM)
2: then if that's ok , the glass in front of the FLOAT bowl shows
fuel lever there is on the line, proper. ! float level.
3: if you look in there and see lots of CRUD, bingo.
4: if dry now, or low, the float valve is gummed up or stuck closed.
5: if fuel is too high it floods.
6: if all the above is ok the carb jets are clogged with junk as all do.
end (super basics carb) we can go like this for days, on carbs.
seen all fails, of all kinds, carbs. endless. they are.
ever fix quadrajets or SU carbs, you seen lots of failures.

Need a schematic on a fuel pump to carb for 1985 LT 250 F

and our schematics only work on our cars.
try mitchells yet, ? that be like first if in fact it is a USA car.
which engine.?
the car world wide used many G engines,
G10 on up and not one is 2.5L
G13, and more,

we cant guess, where you are or what drive line you have
you'd have to say both... and be a win-win.

What would cause the fuse to keep blowing on the fuel pump for a 2004 Isuzu rodeo?

i missed this. an NO engine stated, 3.2 or 3.5 DI?????????
car have the IMMOBLIzer option?
now a real answer , not guessing... just facts, if above true.
1:shorted wires to the pump (end to end ,long)
2;wrong amp fuse. not spec. (the one blown)
3: a shorted pump.
4: fuel pump relay shorted.
5: some fuses on cars (most) run other things too, not just a pump (not this case, it seems
no fuse number stated or engine size)

6: tank dry and this burned up the pump as all do. like that. no gas.? in tank.
7: pump clogged.and impeller jammed.

now Ill read the FSM pages on topic for you.
ok,on the schematic page,3.25
there is no such fuse, in uSA 2004,
its gets power on both engines from the IG1-b1 fuse
fuse eb f15, engine bay = eb
why not tell
that was 3.2
next the 3.5DI (a totally different setup)
ill pretend that next
if eb12 fuse blew (engine bay fuse f12) marked pump
that means, the pump is bad or the pump controller is shorted.
so unplug pump, if fuse holds its the pump
if not?, its the controller
here is proof on the 3.1

try mitchels.
its all there.
no books. ? well, read this,

Where is the inertia switch located on a 2000 Isuzu rodeo?

2000 RODEO.
no engine state , size or cylinder counts. v6, I4 what?
fuel systems vary by "ENGINE" option. looks like both have this.
one more Easter egg hunt.,... buy the FSM book and read>?
were you in a collision?
no symptoms posted. so cant help
some have this switch others not. (no country stated either)
the 1990s v6 cars had one...
i tired first to buy one, and its is sold, here in usa.
see photo, knowing what one looks like helps no?
and anyone can buy parts and see them online.
its only on V6s. and is electric, as clearly seen.
yes it is on some cars, isuzu and most here in usa not.
why not post your country so others can answer .
be the 4th ever to do so, here.
as you may not KNOW, some countries require this on all cars import to THAT country , but not in oUR USA country.
her are all hits on a real forum (250k posts)

see this, its called a site search.
(you need and account to search there) but i can search from outside, using this google magic.

I'D say you dont have one.
the usa PCM drawing shows no such device on the fuel pump relay pages.. nada, on USA spec,cars.
( not perfect but all I have...


why not post symptoms so we can be on the SAME PAGE.
no start?
got full spec fuel pressure cranking>? if yes, bark up another tree.?

How to replace water pump

04 Trailblazer
what engine cars come with many engine options.
my chev had 4.
nobody can guess this, its Impossible. you just look.
if totally clueless just looking, the in USA> open the hood
then , look up, see that EPA sticker under hood,?
that has the engine spec, what it is.
4.3L, VIN X, 8th Digit, the VIN on all USA cars show which engine too but takes time to look up. better is read the hood.
1second test and BAM> my engine is a bla bla.

its ok ,99% ask here how to fix engines they can not identify.
and FAIL big time..
the fsm covers ALL this even the vin decode, on all cars.
and too. login and look. like us.

I now taught you how to fish. no free fish.

Does a 2003 jeep have an inertia switch?

as always check all fuses first....fuse 12,19,and 24, for sure.
which engine,? there are many and a diesel.
each engine has unique EFI and specs....

did you scan the ECU? some engines has DTCs for pump pressure.
look there. using a scan tool.(any in usa work, newer)
my wild guess , car cranks but dont start?
just a clue here.?

looked at and there are no cut out.s.
no inertial, rollover or oil pressure fuel cuts.

the PCM controls 1 fuel pump relay that powers the pump.
we check fuel pressure cranking, to see if it meets spec.
if not , work that,
if good, pressure, then we back up and check spark
fuel is last, not first test.

and if you had a real FSM it does tell you all permisses
for it to allow pump to run.
it cuts fuel for lost spark is one.
or unflood mode.

1: fuses good?
2: all dash lamps glow key on,including the CEL?
3: got spark cranking? if not there will be no fueling by design (logic)
4: if compression is good, the engine runs with test fuel for
say 3 seconds, so you check fuel pressure cranking
and get 0 PSI (the actual pressure, is very important in this diagnosis.
0 , 10psi, 60? ( can be pump, 12v power to pump or regulator bad.)

that is the order, and if you get to #4 we work that.

Which is the fuel pump fuse?

what country, ? and what engine option? ????????????
the pump may not have 12v power until cranked, is engine dead/?
post the systoms so we can understand the context ....
or just curious. has the drawings.

here, ill look for you. USA, and take wild guess on engine.
ok, the toy has a test port conn.
key on, check pressure after.....doing....
Using a jumper wire, short both terminals of the fuel pump check connector. The check connector is located near the air cleaner. Connect the terminals labeled FP and +B.

reasons for pump failure.
  1. If the fuel pump failed to function, it may indicate a faulty pump, but before removing the fuel pump, check the following items within the pump system:
    1. All fusible links
    2. All fuses (EFI-15amp and IGN-10.0amp) "names"
    3. H- fuse (AM2 30A)
    4. EFI main relay
    5. Fuel pump
    6. Circuit opening relay
    7. All wiring connections and grounds related.

i just check pressure cranking, (rubbers meets rode, logic)
if fail, to have 12v at pump i work backwards.
if 12v at pump, then pump is dead if pump is dead.
simple logic, here, and 100% effective.....!

toy spec on pressure is.
The fuel pressure should read 38-44 psi (265-304 kPa).
and running. with MPI engine the pressure will drop 10psi
due to vacuum reg. rules.......etc....

Is OBD2 is can be use in Japanese cars,for diagnosis

Well, OBD2 is an international program to troubleshoot all cars sold in the USA built after 1994.
So if the car was built after 1994 and sold in the USA, OBD2 should work on it.

No fuel delivery from the tank to engine

First check the fuel pump fuse and relay and if they are good then check the fuel pressure it should be 28-32 psi with key on and engine off.If its not within these specs then replace the fuel pump.
