Question about Nissan Cars & Trucks

1 Answer

I want to change the electronic fuel injector (fuel pump) relay in a 1999 Nisan Frontier, 3.2 liter (V6).

I already have the replacemnet relay. And I have a general idea where the old relay is located. It's high up under the dashboard, center of the firewall. You can't see it from laying on your back and looking up for it. My problem his HOW do I get to it? What are the fewest parts I have to remove to get to it? Do I get to it from under the dash or do I have to take off all the dash trim and try and get to it from the top, defroster/windshield end?

SOURCE: Fuel Data Center and Electronic Climate Control not funtioning

This is defenetly the BCM, I had a 1990 with all of the same problems. Buy a rebuilt and install it behind the clove box. Remember that you must install you memory prom into the new unit as they don't come with any in them (it is what is memorizing your miles driven.) You will get off pretty easy on this one as they are available and not too expensive.

it doesn't have a fuel pump relay it has a fuel pump control unit and it is located on the chassis back quarter drivers side near the tube cross member for chassis on top of chassis rail near bed mount. locate the rear springs front perch and it will be above that on top of rail.

hope this helps. good luck and please ask any question you have.

Is there a reset button on a 1999 isuzu trooper 4x4 it won't start acting as if it's out of gas but isn't already replaced fuel pump 2 mths ago

which engine? i cant guess engines, not today, too early.
what will be, will be..... fate always wins... and entropy.
so that is just 2 simple tests.
12vdc (11v cranking) to the pump , across both its 2 pins?
yes, /no of no work to ECU relay (fuel pump relay)
if the relay shows 12vdc cranking and pump
then we check fuel pressure, next.
but that is all wrong..... what do we really do, as all EFI systems can cut fuel for many reasons, besides that pump.
ill guess its a gasoline engine, and still stock end to end. (blind too)
1: head lights glow bright , key off. and cranks fast on demand.
2: key on, the CEL glows, in cluster, it must or ECU lost power.
3: fuses to ECU and pump good...???? all fuses good.
4: i connect scan tool (any tool works in usa, here) at the 16pin DLC port seen near knees of driver. i get comms now. if not say so.... if no comms now, the ecu is dead.
5: I crank for 5seconds release key and if scans show DTC errors of
P03xx codes, now you know why injection is halted, by design.
all cars do that, if up to 3 things spark wise are bad, the ECU cuts all injectors dead. (prevents crash and burn, as seen on TV by law)
so if all that is OK,?
6:then i look and see if injector 1 passes my NOID light test.
yes, then it is injecting. ECU is....injecting. ok. (did its job)
7: i then check for 12vdc (11v cranking) to the pump, if not?, I trace that wire for its obvious failure or the relay bad.
if you have 12vdc to pump cranking (good)
i check fuel pressure next. using a tool called a fuel pressure gauge that costs $20 (ask)

one could skip to test 6 first. (6 bad, start back at #1)

next time post engine in car.
cylinder count at least and displacement.
the line up, last 2 are diesel...
3.2 L 6VD1 SOHC V6
3.2 L 6VD1 DOHC V6 twin cam.
3.5 L 6VE1 DOHC V6
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4

i answered for USA car, and gasoline engine..

I'm looking for a fuel system diagram for my 1999 Nissan Frontier to check the fuel connections from the tank to the engine 3.3 V-6 I recently replaced the fuel pump,fuel sending unit and fuel filter. Not...

Get a noid light hooked up to the injector (Injectors) This will tell you if the injectors are getting the signal from the computer to let fuel out.
You can have a good fuel pump, and still no fuel if this signal isn't good.
On some vehicles, this signal starts from the distributor. (Module or hall effect)
