Does anybody know where the fuel pump control module is cause my car just threw a code for it and I wanted to know if its part of the fuel pump itself or is it in a seperate location.

i read that but that isnt answering my question, does anyone know where it is or is it on the fuel pump itslef.

 

What is the code you got?

 

p1220 = 1305 = fuel pump control module

 

I don't think there is a seperate Fuel pump control module. Basically fuel delivery is controlled by the ECU, fuel pump relay and fuel pump itself.

I glanced through the FSM quickly, but didn't notice anything explicity for the P1220 code. Reset the ECU/CEL and see if the code comes back, perhaps it was a one-time glitch...

 

well ill try to locate the fuel pump relay and see if that needs replacing if not i guess ill have to replace my fuel pump. I did reset it and it did come back. It basically cuts fuel out under anything passed half throttle.

 

looking at the factory manual the FPCM harness connector is in the trunk left side ahead of tail light there are 2 connectors the upper one is the FPCM connector u may want to trace that out see where it goes

 

The fuel pump relay is near the fuse box in the car (IIRC).

I've never heard of this before - keep us posted.

 

What page of the FSM are you looking at..
Thanks!

 

Maybe it's the vacuum switch connected to the fuel pressure regulator? If there is one

 

EC-271 diagram on EC-274

 

I don't see anything on either of EC-271 or EC-274 regarding FPCM... 271 is about P0420 and 274 is about P0440 (both EVAP relateD).

I have two different versions of the FSM, and I checked both...

What is the heading or something I can search by..

 

The FPCM adjusts the voltage supplied to the fuel pump to control the amount of fuel flow

 

I'm using the service manual bought from nissan in 1996 when i purchased car it's a thick black covered book and the title for code P1220 is Fuel Pump Control Module

 

Very interesting. My 96 PDF version doesn't even have P1220 mentioned.. nor does my updated PDF for the entire A32 model.

I do have a picture in my EL module - showing the FPCM as a box that sits under the trunk lining on the driver side of the car. However, I wasn't able to find reference to it anywhere else in the FSM.

What's also strange, is that the FSM says both FPCM and the Fuel pump connect to B21... connect B21 in the harness layout runs only to the fuel pump... so my guess is the FPCM and fuel pump are one and the same... and the functionality has been integrated.

Time for a new fuel pump...

 

I just noticed that it says california models only. I also checked my electronic fsm and that does not show it either. but its in the nissan service manual.

 

Well i changed the pump and im still getting the code. Is there a module but only for california models. On my scan tool that reads live data the map sensor seems to not be functioning cause the engine doesnt seem to sense load on the load calculator and the map sensor isnt rising. would this this then casue the FPCM not to function since it cant read manifold absolute pressure, which would be the reaason why the car cant be driven past half throttle and not recieve enough fuel, anyhting more and its just dogs its way up the rpm band past 3500.

 

bump anyone......

 

C'mon i know somebody is reading this that can help me out, Ill just have to buy a new map sensor. Does anyone have a vacum diagram layout for this car.

 

Apparently there are more than one having this problem me too. I throw the p 1220 FPCM but cannot fine it in the haynes manual or any reference to it but my code reader says that is the code and calls it the fuel pump contorl module. where is it what are the possible causes for the code and what is the most common cause? my NissaN IS A 2000 MAXIMA CAN ANYONE HELP?

 

 

Drivers side trunk behind the wheel well.
