INTERMITTENT NO START REPLACE TERMINAL CONTACT TANG. Cadillac Allante 1990

For 1990-2009 cars

# INTERMITTENT NO START REPLACE TERMINAL CONTACT TANG

#### SUBJECT: INTERMITTENT NO START OR LOSS OF PERFORMANCE

#### MODELS AFFECTED: 1987-1992 ALLANTES

Some 1987-1992 Allantes may experience an intermittent no start or loss of performance condition. This condition may be caused by a loss of fuel pressure. A symptom may be that the engine will operate normally for a period of time (i.e., 30 minutes continuous running time) before the condition occurs. This condition may be caused by insufficient terminal contact for circuit 120 (fuel pump power circuit) in connector C403 for the fuel pump/sender unit.

To repair this condition separate C403 and visually inspect the female terminals for circuits 120 (power) and 1034 (ground) for a deformed terminal contact tang. Refer to Figure 1. If a deformed contact tang is found in either terminal, replace it with P/N 12047767. Terminal P/N 12047767, crimping tool, and terminal removal tool are included in "Terminal Repair Kit" J-38125. This part is currently available from GMSPO.

#### NOTE: DO NOT reform the contact tang in an attempt to repair this condition. If the tang is reformed, it will not exert the proper clamping force against the mating terminal allowing the condition to recur.

If the terminal contact tangs are not deformed, refer to PFI System Check Chart in Section 6E of the appropriate Allante Service Information Manual for diagnosis.

For warranty purposes use Labor Operation T6616 at .5 hour to replace terminal(s) in connector C403.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
