ECU is grounding the fuel pump relay. ECU
ground this relay for the first 2–3 seconds after
key on and any time RPM is seen from the CPS
ECU is not grounding the fuel pump relay. Pump

–
Typical ignition timing on a warm engine at idle
Typical max spark at wide open throttle
Average reading on a warm engine at idle
Unit is start-up enrichment or under rapid
acceleration
should be close to ambient air temperature.
Warm engine at idle may cause reading to be
higher
ECU is not triggering the pump to run. Seen
when key is ON but engine is not running
Vehicle is running and pump is active
Engine not running and unit is near sea level
Normal reading when warm engine is at idle
Normal reading when unit is 1/2 throttle to WOT.
value will be higher on a turbocharged unit
Typical warm idle. Cold start up reading will be
higher
ECU is limiting the RPM
ECU is not limiting RPM
High, Low, Neutral, Reverse, Park
