P1626 on Chevrolet
On Chevrolet, GMC and Buick, the engine computer is not receiving the fuel-enable message from the theft-deterrent system
Severity: Severity not verified — if the car runs badly, have it inspected
GM bulletins tie P1626 to no-start and hard-start, so the car may not start or may stall, but none of the sources rate the risk. An Equinox owner reports a limp-mode shudder with the code.
This page covers only what differs on Chevrolet. For what P1626 means, the ranked causes and the test order, see the P1626 guide.
