My car starts up really bad in the morning and when I let it sit for a while. I dont have cold start on there but before it used to start up great without it even in the cold. Now for some reason I dont have fuel pressure in the fuel lines when I take them off. Before it used to spray out when I took off fuel rail now there is nothing but air in there. So when I start it up after it sits it takes a while to crank to get the gas in there and then it dies right away since the gas is going through the rail with a lot of air still in there. So I cant find the problem and thought maybe you guys could help me out.

thanks

It could be your fuel pressure regulator.Or a check valve somewhere.

I just replaced the fuel pressure regulator and its still the same... its the thing on the secondary fuel rail that has a vacuum hose going to it right?

Where are there check valves and how do I check them?

The check valves are loated in the fuel pump itself I believe.But before changingyour fuel pump,check for leaks.also when you remove the cover over your fuelpump check it for leaks.cover all the basics.

Ive already swapped the fuel pumps with the one i had in my parts car and that didnt do anything.
