Fuel leaking at or near injector rail

Fuel leaks are diagnosed by pressurizing the fuel system and inspecting for the leak source. The fuel system can be pressurized by simply cycling the ignition key to the ON position; the fuel pump will come on for about three seconds to "prime" the lines, then turn off. The pressure will remain on the fuel in the lines so inspection can begin. Fuel leaks in the engine bay can originate from fuel lines, the fuel rail or fuel injectors. If the origin of the leak is not visible, it may be necessary to remove certain engine components to gain the necessary access. I find it helpful to locate the fuel injectors first, then follow the rail to the lines and keep working rearwards until the source is located.

engine hard to start smelling fuel first look under hood for signs leaking fuel lines if you raise hood get strong gas smell look for wet fuel leaks on top engine where fuel lines located.if see no leaks could have leak at fuel rails to fuel injectors.if see no leaks look under vechicle around fuel tank area look for fuel dripping.

LOOK UNDER THE HOOD AROUND THE ENGINE FUEL LINES LEADING TO FUEL RAILS FOR PETROL LEAKS AND LOOK UNDER CAR AROUND FUEL TANK AREA.LOOK FOR LEAKS AT FUEL LINES.REASON VECHICLE NOT STARTING FUEL LEAK TAKING AWAY FUEL PRESSURE.FUEL LEAK HAVE TO BE AT THE FUEL PUMP FUEL LINES OR YOUR FUEL INJECTORS OR FUEL RAIL HAS A FUEL LEAKS AT THE O - RINGS.

Take it back and he will fix it, maybe a o-ring where the fuel line connects to the fuel rail or if he removed the injectors, then a o-ring maybe pinched, loose fuel line fitting. something minor, but dangerous, can catch fire real easy, I would have it towed to be safe.

disconnect the fuel lines at the fuel rail.then follow the fuel rail to disconnect every thing fastened to it,find the hold down bolts that fasten it to the motor(intake).unbolt the bolts.now you should blow any dirt around the areas were the fuel injectors go into the intake.disconnect the injector electrical plugs.pull the fuel rail and injectors together out of the car.you may need something to pry the rail/injectors up as it will be stuck to the intake.once out then you can remove the locking clips that hold the rail to the injectors and separate the injectors from the rail.install the injectors into the new rail in the same position as they were in the old rail.use a lubricant on the O rings when installing the injectors onto the new rail and insert the lock clips.lube the injector O rings on the end that goes into the intake and re-install in reverse order.reconnect items in reverse order and you can start the car.check for gas leaks.NOTE:if the O rings are cracked of broken replace with new injector O rings.

you don`t say what motor is in this so here is a basic procedure, find the fuel rail where the fuel lines connect to at the intake manifold.disconnect the fuel lines(be carefull you could get gas in your eyes from fuel spray or start a fire due to hot engine)these lines have high pressure fuel in them.look at the fuel rails to see what all is in the way to remove them and remove interferance items.remove the bolts that hold the rails to the intake manifold,gently lift wiggle the fuel rails and you may have to pry up on the rails in places to get them to come out with the injectors attached the rails.you should make sure any debris is removed from around the injectors so no dirt falls into the injector holes before you remove.then you can remove the injector to rail lock clips and remove the injectors from the rails.clean areas were the injectors will be going apply either gas or silicone on the injector O rings then install injectors to rail install lock clips and reassemble.replace all the O rings as they get dried out brittle and crack or split.re-install removed components start car and check for fuel leaks.

Where is it leaking? If its at the fuel rail fuel pressure regulator you may need a new regulator if leaking on the metal part. If its leaking at the rail side its just the "O" ring. Relieve fuel pressure(push in valve under plastic cap right side beside alternator on rail. Remove the torx screw holding regulator bracket. Pry out and replace "O" ring, reassemble. If its not the regulator it may be a fuel injector, you need to remove the fuel rail and replace both the upper and lower injector "O" rings. This however needs the intake manifold removed to repair.

It can only be a small area. Does it seem to be coming from the fuel rail area, which is usually chrome color. The fuel pressure regulator or fuel line. The fuel line come up the driver side firewall connects to a regulator, and then feeds into the fuel rail. Any of these connections could be the leaking source. Also one of the rubber o rings for the injector could be leaking. Look to see where it mostly looks to be coming from and feel around the pipes for the gas.

I have had this problem on my 89 and my 94 gm trucks what it was is the pick up inside the distributor time to rebuild it (not the cap and rotor) the little thing inside with all the wire wrapped around something- copper wire with a clear coating on it the coating get hot and cracks causeing it to ground out when the vehicle warms up run ok until u shut it off then no start or runs rough

I would trace fuel lines from tank to fuel rail on motor. These are high pressure lines so do not try to quick-fix them. You will have to measure the lines and replace them if they are leaking. Unless the fuel is leaking from lines by fuel rail or by fuel filter.
