This causes hard starting, rough idle, and a strong fuel smell from leaking fuel inside the intake manifold. Repairs typically run $200-$600. Severity: high.

Common fuel pump failure. The Safari twin-tank models have additional complexity with the tank switching system. Repairs typically run $400-$800. Severity: medium.
What is the 1990-2005 GMC Safari Rear Dutch Door Latch and Hinge Failure?
