Fix the Ford P1233 FPDM Fuel No Start Problem
Here's a fix for that no-start condition on 2004-2008 Ford trucks
. The FPDM
(fuel pressure driver module) usually shows up as a P1233 diagnostic trouble
code (OBD-II) when the truck's
codes are read. A Ford P1233 code is described
as Fuel Pump Driver Module Offline
or Fuel System
Disabled or Offline
. A search on Google for Ford P1233 shows that this
P1233 DTC code is not limited to being a problem on just Ford trucks. Others
with the Focus, Mustang, Town Car
, etc. also experience this problem.
You may experience stalling, no-starts, random no-starts, or other potential
symptoms. A quick search over at MotorcraftService.com (a Ford service web site),
they offer the following possible causes if the P1233 code is triggered:
- Inertia fuel shutoff (IFS) switch needs to be reset.
- Open FPDM ground circuit
- Open circuit to FPDM PWR RLY
- Open FPDM PWR circuit
- Open or shorted FPM circuit (engine should start).
- Damaged IFS switch.http://www.fordf150.net/images/articles/fpdm4.jpg try link hope this helps it may be it would hate for you to change fuel pump and it not be fuel pump
