Injector Spraying Fuel Into Engine Bay

Okay, so, now that I have gotten a new clutch, machined flywheel, new pressure plate, pilot bearing, etc. I drove the car around a bit, and later in the day, looking under the engine bay I noticed fuel spraying from the area of one of the fuel injectors. I tried to look very quickly at where it was coming from, and it seemed it was coming from the injector for the front rotor housing. I didn't let this persist, I turned off the car so as to save to fuel, but does anyone have any suggestions for this problem? Do I need new injectors, or do I just need to tighten or fix something small?

You may just need new O-rings and/or pintle caps for your fuel injectors. Make sure your fuel rails are or were bolted down properly.

Be sure to get this fixed before you drive your car again. (Common sense)

I had this same problem. For me it was alittle to late till i realized it though.. My O-Ring had a little knick in it. didnt know till my car was on fire at a rest area... lol i got the fire out in time though, where i only had to replace some hoses, wires and some sensors.. My advice would be to check the orings first.

What you might do is this................pull the upper intake off the engine. Turn the key to just ON.

Jumper the fuel pump check connector while looking at the area of the primary fuel injectors you suspect being faulty. When you jumper the fuel pump check connector that act makes the fuel pump come on and pressurize the fuel rails. Unjumpering the connector will make the pump turn off.

That is what the fuel pump check connector was designed for.......for being able to pressurize the fuel rails/injector to look for possible leaks prior to installing the upper intake.

I'd buy one of those small fire extinguisher if I were you to have handy in case a fire starts. Cost is very little for one of those extinguishers.

In the past I had a pinhole leak in a fuel hose connecting the primary fuel rail to the secondary fuel rail. Sprayed a fine mist and was found by doing what I suggested.

Probable the orings like the others mentioned.

Hahaha, yeah, I started it one more time for about 20 seconds just to be sure it was coming from the fuel rail area
