I took my 2004 Olds Alero to a repair shop because I smelled gasoline fumes in the passenger cabin. Their diagnosis is that three of the six fuel injectors need to be replaced at an estimated cost of $900-950 ($600 of this is parts). An acquaintance who is a mechanic told me he's never replaced three fuel injectors at once and very rarely replaces them at all on GM cars. What could cause three fuel injectors to need to be replaced at once? Should I be worried about the other three? What else should I ask the shop before authorizing the work?

I have never seen more then one injector fail at a time on a gm vehicle and that's uncommon for one to even go bad. I replaced them for not working at all not opening and closing and letting fuel in the engine. I have seen one just pour fuel in the engine also. I would be asking what about those injectors being bad is causing the gas smell?Are they leaking fuel outside of the engine? Can you smell the fuel smell without it running? Did look at it to see why they were saying they were bad?

The car runs fine and I don't smell fuel when it's not running. Another mechanic I asked online also said it was rare for fuel injectors to need to be replaced. He said maybe just the O-rings need to be replaced; and other possible suspects are the fittings for fuel lines or purge solenoid. What do you think about these ideas? Thanks!

If you have a purge solenoid issue or a leak in the evap system you would set a code. Is the check engine light on?Also if its running good I would question even more why do you need those injectors replaced. Maybe there just leaking externally which you can replace the orings if that's the case. Without looking at it I really don't know for sure. But so far I amnot cconvinced you need those new injectors. Let it idle and look under the hood where the injectors he is saying need to be replaced. See if you can see fuel leaking somewhere?
