Default Do You Have A 1093 code?

Take a 1 ltr. container like a used pop bottle and tie it up under the hood over by the brake master cylinder. Locate the drivers side fuel rail and follow it to the back end of the rail. About 1" from the end of the rail you will find a small black hose connected onto the rail. Remove the hose from the rail and plug the hose with a bolt and clamp. Route a new hose from the fitting on the rail over and into the container you tied up making sure the hose stays down inside the container. Go out and make the truck do the P1093 problem then pull over and open the hood and check the bottle for fuel. If there is no fuel in the bottle your safety fuel regulator is fine and your problem is most likely a fuel supply issue. If there is fuel in the bottle you have a regulator problem and I would take it to the dealer and get it fixed. Other may tell you to shim it but I would rather get the safety regulator fixed properly. Don't leave the test setup on forever once the test is done hook it back up to the stock setup.
