Hi guys, I have a 92 firebird v6, I did a fuel pressure test on my car and its getting 39 psi, and it is getting spark, sometimes I can get it started for about 8 seconds then dies, it runs rough, I think there is a weak fuel pump, I don't see how it can stay or start running on 39 psi, I use to once a week let the car run for 10 mins as it is not good to let it just seat there, when the fuel got low I would get a gas can and put 5 gals in, this went on for about 5 weeks, after a while when I started the car it run rough, while I replace the fuel filter then It just got worse and wouldn't start, I hope this made since.

Original fuel injectors? 39PSI is close enough. Stock Multecs in 2019 would be a lot more likely failure.

Is the car being driven ? Or sitting? Seriously they need to be used to keep them going , a full tank of gas and injector cleaner and a good run , it might just clear up . Is the computer throwing any codes ?

Dustin Hinton

I change the plugs and wires, everything else is stock, the ecm is not throwing any codes, the car is been sitting I don't drive the car

I had a similar problem. It was the injectors. I got some from Southbay and it started up and ran fine after.

Are there any posts on here that tells how to change the injectors, since no one else is saying anything more

It's pretty easy. You just take the top half of the manifold off, 8-10 screws? take the air intake off the TB, and I think it's 4 screws for the fuel rail. I didn't even disconnect the feel and return lines to the rails, I just flipped the rail assembly over to the DS fender and rotated the injector clips.

Thanks, what's the site you got your injectors?

South bay, a site supporting vendor. If you tell them you are with TGO you get 10% off. Link is on the side bar --->

i got the intake half off, how does the injectors come out?

Piece of cake .I have done it so many times. I can have it tore down to the manifold in less than 5 mins flat. What I do to remove injectors is not even bother with the fuel lines. Just leave them connected and remove the 2 bolts holding the fuel rail down and simply flip the fuel rail over with lines and all towards the driver side and remove injectors that way. I can swap injectors in 10 mins flat.

Sounds good now how does the injectors come out

There are little clips that you have to 1/4 turn in the rail to get the injector out. I mentioned that in my other reply.
