How many fuel pumps does a ZR-1 have?
The ZR-1 has two fuel pumps. If the secondary pump does not operate the engine will run lean for fuel over 5000 rpm and a ‘Check Engine’ error code 55 will occur if the condition persists for two seconds. On cars built after about 1990 VIN 400 there is a fuel pump test connector near the wiper motor. It has one red wire.
