Subject: | Intermittent Harsh Shift Into Reverse and/or Engine Start then Stall, with MIL On Intermittently with PCM/TC DTC 43 Stored in Memory (Replace Fuel Pump Relay)

Models: | 1995 Saturns equipped with automatic transaxles

### Condition

Some vehicles may exhibit an intermittent harsh shift into reverse and/or an intermittent stall when starting thevehicle and shifting into Drive. Also, the malfunction indicator lamp (MIL) (SERVICE ENGINE SOON telltale lamp) may be ON intermittently. When performing diagnostics, diagnostic trouble code/transaxle controller (DTC/TC) 43 may be present in PCM memory. Information flag 68, 71, 73, 76 and 79 may also be in PCM memory.

### Cause

Some fuel pump relays may have improperly assembled internal contacts, which may intermittently cause high resistance across the contacts. This high-resistance across the contacts causes an intermittent high resistance in the circuit, setting DTC 43 and causing the PCM to go into transaxle back-up mode.

### Correction

Perform the diagnostic procedures in this bulletin to determine if the condition is caused by the fuel pump relay.
