I have a 91 rs camaro v6 3.1

so last night when getting ready to go home the car started I backed out of my parking spot and as I pushed in the clutch to shift into first the car died and wouldn't restart , engine turns just fine (proper speed )

I noticed that I don't hear the fuel pump winding up so I think thats the problem
I had replaced the pump aprox 3 years ago so I'm surprised to have another one go bad this fast

looking at a couple posts here they talk about relays under the hood
I can't find any mention of these type of relays in my auto manual

does a 91 rs 3.1 have under hood relays and where would they be located


also when trying to use a wire to test codes I only get the code 12 which I understand signifies that it is in a diagnostic mode . now it dosen't reveal any codes it only flashes the 12 code continuously
is there a good way to test the ecm computer to see if the problem lies there


any help and advice would be appreciated
I realy don't want to have to pull the tank again only to find the problem is something else


thanks , John

When i tested my code I just took a plain wire any wire will do and plug them into bank A and bank C I think dont quote me its either bank A, C Or B you have to jump the 2 together it will flash cose 12 then it will flash you code. If it is the fuel pump I have a very easy way to replace it I just did mine

the car is 17 years old.. No one has ever changed the pump.. You're looking at 85 bucks max. CHANGE IT

Hes said he replaced the pump three years ago. did you check the fuse under the dash
