How to Check the Fuel Delivery on a Pontiac Grand Prix

66

The Pontiac Grand Prix is a General Motors product that debuted in 1962 as a two-door coupe in the luxury class. The Grand Prix was produced as such until 1988 when it shifted to the midsize class. A four-door sedan body type was added in 1988. Both versions were marketed until 2004 when the coupe was retired. The four-door sedan was retired and ceased production in 2008. Investigate the Pontiac Grand Prix fuel delivery system if the engine starts running rough, stalls out in traffic or won’t start at all.

Check Fuel Delivery

Relieve fuel system pressure. Disconnect the negative battery cable and loosen the gas cap to let pressure drain from the system. Attach a dual tube pressure gauge to the test port and drain the fuel into an approved container.
