My 97 Dodge starts and dies every now and then but if I push the gas pedal down just a little it will start right up and it runs just fine and other times it dosent do it at all I even changed the fuel filter and it still does it now and then its not a big deal but I was just wondering if anyone has any ideas?

 

my 97 did it and i had to put injectors in it

 

Over flow valve. Possibly lift pump.

 

I think the lift pump is good because when I changed the fuel filter it still had some air in it but it started without cracking the injector lines.Where is the over flow valve and how hard is it to change?

 

OFV is on the back side of the pump it's the banjo bolt on the return line.

 

Tork Tek has an adjustable OFV for $46

 

What if my fuel screen is dirty would that do it?And is the ofv bad about going out and how do I adjust the adjustable one do I need a fuel pressure guage?Can u take the ofv apart and clean it or does it just go bad and u have to change it?

 

It could but I think it would just be harder starting than starting and dying. OFV spring gets weak and will pop off at lower psi letting fuel go back to the tank instead of holding it in the pump. You can stretch the stock spring and I have heard of people putting a spring out of a bic pen inside of the stock spring to make it hold better for a cheap fix. Tork Tek p7100 OFV's are pre set to 30-32psi and can be adjusted by turning the set srew on top in or out. You shouldnt need a fuel pressure gauge.

 

What is the psi of a stock one?

 

think its like 27psi???
