1400201 - LONGER THAN NORMAL ENGINE CRANK TIME PRIOR TO ENGINE START
Date: 03/16/01 (supersedes 140600 dated 09/15/00)
Model year(s): 1999-2001
Description: This bulletin involves the repair of the fuel pump module. The customer may experience a longer than normal engine cranking time prior to engine start. This condition may be caused by fuel pressure loss due to a worn sealing ring within the fuel module.
NOTE: QUALITY ANALYSIS HAS REVEALED THAT A WORN SEALING RING IS THE PRIMARY REASON WHY THE FUEL MODULE IS REPLACED FOR FUEL PRESSURE LEAK DOWN. IT IS RECOMMENDED THAT THE SEALING RING BE REPLACED BEFORE A FUEL MODULE ASSEMBLY REPLACEMENT IS ATTEMPTED.
Details:1. Start and run the engine. Verify normal fuel system pressure of 339 kPa +/- 34 kPa (49.2 psi +/- 5 psi).
2. Stop the engine. Verify that the fuel system pressure does not fall below 207 kPa (30 psi) in less than five (5) minutes.
3. If the fuel pressure does not fall below 207 kPa (30 psi) in less than five (5) minutes,then the long crank time may not be due to the fuel system. Further diagnosis must be made to the entire engine system.
4. If fuel pressure does fall below 207 kPa (30 psi) in less than five (5) minutes, then refer to TSB 14-05-99 for additional fuel system diagnostic assistance.
5. If diagnosis determines that the cause of the fuel system pressure loss is due to the fuel pump module, then inspect the fuel pump module part number label for its assembly build date code (Julian date). The part number label is affixed to the fuel pump module wire harness (pigtail), near the electrical connector to the body wire harness.
6. Inspect the bottom row of numbers on the fuel module label and locate the module build date code. Determine the date of build (Julian date) for the fuel module assembly. The first two numbers in the date code indicate the calendar year (1998 = 98, 1999 = 99, 2000 = 00, 2001 = 01), and the remaining three numbers in the code (1 to 365) represent the day of the calendar year (Figure 1).
7. If the module part label indicates that the fuel module assembly was built on or before November 04, 1999 (Julian date of 99308), then a spacer must be used with the sealing ring. The split washer in the repair kit is used as the sealing ring spacer.
NOTE: FAILURE TO USE THE SPLIT WASHER, AS A SPACER FOR THE SEALING RING (WHEN REQUIRED), MAY CAUSE EXCESSIVE MOVEMENT AND DAMAGE TO THE SEALING RING.
8. If the module part label indicates that the fuel module assembly was built after November 04, 1999 (Julian date of 99308), then a spacer must NOT be used with the sealing ring. The split washer in the repair kit can be discarded.
NOTE: SOME REPLACEMENT FUEL PUMP MODULES, BUILT AFTER NOVEMBER 04, 1999 (DATE CODE 99308), HAVE BEEN USED TO REPLACE FUEL MODULES BUILT PRIOR TO NOV. 04, 1999. IT IS IMPORTANT THAT PRIOR TO EACH REPAIR THE MODULE DATE CODE BE PROPERLY DETERMINED.
