I have a 89 rs camaro with a 2.8l v6 mpfi and i just replaced the fuel pump because it did not provide presser and would not hold now that the new ones in i cant start my car and after i try to and turn off my car my fuel pump makes a lot of nosies i tested the new pump and it shows 47 psi and slowly drops. plz i need some trouble shooting ideas.

 

I think you may have put in your pump upside down

 

Can you hear the pump running when you put the key in and turn it to the run position?

 

yes i can

 

How would it be upside down

 

Check to see if you are getting fuel to the fuel rail by pressing on the bleeder valve on the rail. If none comes out, you might need to replace the filter. I would post this in the 3rd generation area and maybe get quicker replies from people who have replaced the pump on your model.

 

ok i will and i have done that and gas is commin out if it but not every ime is that a problem?

 

You should get gas out of the bleeder valve every time you turn the key to the run position and hear the pump running. It should pressurize the system. If not, you might want to check at the fuel filter and see if gas is pumping through it. Did you change it when you changed pump?

 

i have checked them all ready
