Its your fuel pump.I had the same plomblem not too long ago.I was spraying either in to start it.I have a 97 chevy truck witch requires 65 psi to start and 55 to run properly.You need to find out much psi you need to start it.You can probaly look in your manual or just make a few calls.My truck had 55 psi and it ran fine i just had to get it running first.Good luck.I wonder if that fuel pressure regulator was a waste of time like it was for me.

Hello! There are a couple of possibilities for your issue:
1) Fuel pump relay - this tells the fuel pump resistor to turn the fuel pump, either in high or low mode.
2) Fuel pump resistor - see above (very common issue)
2) Faulty fuel pump
Hope this helps and thanks for using FixYa!

sounds like the injector got stuck close because of sitting so long....take em out and cleasn them up real good an try that it should work make ensure the wires have a good solid connection and no bent pins.

I just replaced the fuel pressure regulator and now I am hearing a vibrating noise from the fuel line under the truck. What do you think the problem is.

Sounds like a Solenoid might be bad on the starter if it spins freely and a high rate of speed without engaging.
Also, the relay could be bad.
I am ot sure if the fuel filter and pressure regulator would cause this problem.
No code will show with a bad starter or bad relay, I don't believe.
Good luck with this one.
