P1237 --Fuel Pump Secondary Circuit Malfunction

I would be here all day to write what is in the
service manual

I will guess that the Fuel Pump & hope that is
your only issue,is failing in such a way, it is sending
the wrong info to one of your Modules.

You will need to have a shop with a scanner
look at the codes,data & I would scope the
pump it's self. That & it's age,pretty much
tells you if it needs to be replaced

I'm thinking you took it to a point and guess shop.? I think it is this, Nope, Now I think it is this, nope......Well I'm thinking it is a bad fuel module, because of where they locate them. Could just be the plug, corrosion. I'm also thinking you have a bad ground also. I'm also thinking you should find another shop, And demand your money back for a misdiagnosed job, that didn't fix the problem.

How I to solve a P1237 Code ?


I would start by making sure the harness was not pinched during the install of the tank. I believe the FPMD is under the rear right seat or on that side, in the trunk.

2001 ford focus code p1237 showin will not run how do i fix it


Hi hope I can help.
P1237 : fuel pump secondary circuit FD driver module.
What you need to do is check the voltage at the fuel pump.
Hook your meter to the fuel pump and have a helper turn on the key.
You should see voltage for 2 seconds , you can also hear the pump buzz when it turns on.
If you don't hear the pump turn on, but you have 12v at the pump your fuel pump has failed
If you don't get nether pump or voltage . then check your fuel pump relay.
Hope this helps Please leave feedback
FixYa.

I have a p1237 code, what does it mean. and what can i do to fix it.


P1237--Fuel Pump Secondary Circuit Malfunction

It could be an issue with the fuel pump
Also there are several other steps to follow,
before arriving at a bad pump
Most involve some type of short, detected in the
wiring along the way.That is the short explanation

You really need a diagnostic trouble chart to follow

So,you will have to seek help at a local repair shop
I wouldn't give away extra money at a dealer.
