I am now officially 86'd from my only dealer within 200 miles, Robberson Ford Mazda in Bend, OR !
Even after always being nice and courteous to them, always.
The Idea here is that if you never come in for scheduled service (lost income for them), have many warranty issues, that the formula tells them your a bad investment and once your 36k warranty is expired, your HISTORY buddy. And Mazda can do nothing about it. This is why manufacturers hate the dealer network so much.
I own two newer Mazda's. Never again.

PS the dealer is refusing to fix the fuel pump even though it's still a warranty item under the 60k warranty. They are denying I ever brought up a symtom for this issue! Ha.[/align][/align]Here's the text of the TSB[/align][/align]

This bulletin supersedes the previous bulletin issued on 03/27/08. The REPAIR PROCEDURE has been

revised.

APPLICABLE MODEL(S)/VINS

2007-2008 Mazdaspeed3 vehicles with VINs lower than JM1BK**** ** 859606 (produced before November 22,

2007-2008 CX-7 vehicles with VINs lower than JM3ER**** ** 196510 (produced before November 19, 2007)

DESCRIPTION

Due to low fuel pressure at the high-pressure fuel pump, some vehicles may experience the following:

• Rough idle, stall, and/or hesitation under cold conditions.

• Intermittent lack of power during acceleration when the engine gets hot.

• MIL turns on with DTC P2177/P2187 (fuel system too lean at off idle).

This is caused by a delayed fuel pressure build-up from the high pressure fuel pump. There are two main reasons

for this:

1. The drive current from the PCM is not enough for some fuel pumps.

2. Some fuel pumps have slower response.

To fix the problem, the PCM software and the specification of the high-pressure fuel pump have been changed.

Customers having this concern should have their vehicle repaired using the following repair procedure.

REPAIR PROCEDURE

1. Reboot the IDS to clear memory before reprogramming.

2. Using IDS 51.9 or later software, reprogram the PCM to the latest calibration (refer to “Calibration Information”

table) by following the “Module Reprogramming” procedure.

NOTE:

• Always update the IDS tool first, then follow on-screen instructions to download the needed calibration

file for PCM reprogramming.

• It is not necessary to remove any fuses or relays during PCM reprogramming when the IDS

screen prompts you to do so. You may accidentally stop power to one of the PCM terminals and

cause the PCM to be blanked, or you may receive error messages during the IDS reprogramming

procedure.

• IDS shows the calibration part numbers after programming the PCM.

• Please be aware that PCM calibration part numbers and file names listed in any Service Bulletin

may change due to future releases of IDS software, and additional revisions made to those calibrations

for service related concerns.

• When reprogramming a PCM, IDS will always display the “latest” calibration P/N available for

that vehicle. If any calibration has been revised/updated to contain new information for a new

service concern/issue, it will also contain all previously released calibrations.

•

the vehicle battery and turned ON to a maximum charge of no more than 20 AMPS to

keep the vehicle battery up to capacity. If you exceed 20 AMPS, it could damage the VCM.

3. For vehicles built before April 7, 2007 that are experiencing the conditions as noted in this service bulletin

after the PCM calibration update, perform a Warranty Vehicle Inquiry using your eMDCS System and

inspect Warranty Claim Inquiry Detail for high-pressure fuel pump replacement.

• If no prior history of replacement, replace the high-pressure fuel pump. Refer to MS3 online instructions

or Workshop Manual section 01-14 FUEL PUMP UNIT REMOVAL/INSTALLATION.

• If the history indicates part number L3K9-13-35ZB was used during a repair, use the following illustration

to inspect the production date of the high-pressure fuel pump. Replace it if the production date is before

March 26, 2007.

Date of production is marked as a 4 digit code “YMDD” at the pipe.

Y for Year 4 for 2004....7 for 2007

M for Month 1 for Jan....9 for Sept, X for October, Y for Nov, Z for Dec

DD for Date 01 for 1st of month....31 for 31st of month

Example “4Z16” means Dec 16, 2004; 7608 means June 8, 2007

CAUTION:

collar is present before reinstalling the pump. Failure to do so will result in excessive engine

noise and the subsequent failure of the high-pressure fuel pump and its cam lobes.

4. After performing the PCM reprogramming procedure, verify the repair by starting the engine and making

sure there are no MIL illumination or abnormal warning lights present.

NOTE:

• If any DTCs should remain after performing DTC erase, diagnose the DTCs according to the

appropriate Troubleshooting section of the Workshop Manual.

• After PCM reprogramming, it is no longer necessary to road test the vehicle to “relearn” KAM

(Keep Alive Memory).

5. Fill out an “Authorized Modifications” label (P/N 9999-95-AMDC-97) with the new PCM calibration information,

your dealer code, and today’s date.
