Okay. I checked the pressure and now it's 35-40. How could this be when the truck was running fine before it stopped? Could it be the fuel pressure regulator and if so can you give me a detail easy describtion on how to get to it. I know that it's in the Intake manifold. I'm really lost now.

 

If you remove the intake ductwork and open the throttle, can you smell a strong odor of raw fuel? If so, then it is possible that your FPR is shot. I would first check and make sure that your fuel pump is getting full voltage.

 

Okay I will check for that I also have a question. Is replacing the FPR a time consuming and difficult job or on the same level as replacing an ignition switch and if not what is the average time to do a job like this.

Thanks

 

Okay. I got to the FPR and man was it shot! I wonder was the replacement of the new fuel pump just enough push to force the old FPR to the point of going or was it already on it's way out. Just curious

 

I have now replaced the Fuel Pressure regulator, ignition switch, fuel pump and fuel filter and last night I did the fuel pump test by putting a 12v supply to the red fuel pump test wire and making the fuel pump run. I heard it primming but the psi only reached to about 45. So now I am lost,confused and I don't get it! It was running fine when the fuel pump was first put on then after about 70 miles started to stall and then when I cut it off it developed the no start problem. I need Help. Maybe mental if I can't figure this out LOL!

 

1. Don't assume that the fuel pump is not the problem since you replaced it. Quality control may have let you down and let this one slip by....

2. You need at least 55psi to start the truck if it is only 45psi then the only other solution is to find out why the difference and I would take you back to the fuel pump new or not...
