daltonmcgill7 Posted January 22, 2013 Share Posted January 22, 2013 My injectors are leakingfrom the rail and manifold. What do I do to fix it it won't start? Link to comment Share on other sites More sharing options...
Alexia Posted January 22, 2013 Share Posted January 22, 2013 The O-Rings around the injectors may be the culprit. Standard Motor Products #SK9 - $3.53 on RockAuto.com If the injectors are cracked you will need to replace the entire injector. Link to comment Share on other sites More sharing options...
Eagle Posted January 22, 2013 Share Posted January 22, 2013 Be glad it won't start. Trying to run it with leaking injectors is just inviting it to catch fire. Link to comment Share on other sites More sharing options...

If you put them on all the way into the fuel rail and head, they shouldnt leak. I don't remember where I got them, but I got 6 rebuilt high-impedance injectors for $120 and they work great, I gained power but lost a little mpg. They snapped into the head real easy, but I sprayed carbeurator cleaner on the rail-end injectors (because it was a tight fit) and the whole thing slipped on. I believe the black rings go on the rail-end and the brown ones go in the head. Link to comment Share on other sites More sharing options...
daltonmcgill7 Posted January 22, 2013 Author Share Posted January 22, 2013 Mine were all brown I'm thinking they have me the wrong ones does anyone have the exact part number? Link to comment Share on other sites More sharing options...
ParadiseMJ Posted January 22, 2013 Share Posted January 22, 2013 FIRE BAD !!! Replace the whole bunch of them. If you go to the auto parts store you'll find out that EACH stock injector costs $50-$55 ...aka $300+...(I just about crapped myself). For that price you'll get the same old leaky style injectors. I bought these for both my rigs...they're great. http://www.ebay.com/itm/GENUINE-BOSCH-III-4-HOLE-UPGRADE-FUEL-INJECTORS-87-98-JEEP-4-0-TJ-WJ-XJ-YJ-ZJ-/150983767270?pt=Motors_Car_Truck_Parts_Accessories&hash=item23275574e6&vxp=mtr They come with o-rings and are ready to pop in. Do it!! Link to comment Share on other sites More sharing options...

Comanche County Posted January 23, 2013 Share Posted January 23, 2013 Leaky O ring aren't so bad. Seriously, a little engine fire never hurt a Jeep. It'll clean up the built up oily residue on the inner fender wells and firewall. Just ensure that when the fire starts, you have a proper extinguisher and let it go for a while to burn off any oily deposits. It'll be a lot easier than scrubbing the engine compartment.

They called it a fuel rail o ring kit. It came with 12 o rings and a little tool to put the rings on the injectors. Just remember there is a little metal spacer disc thing on the rail side of the injector that you will need to keep up with. I need to check my pictures from the other day that may help Link to comment Share on other sites More sharing options...

Blue88Comanche Posted January 23, 2013 Share Posted January 23, 2013 I could only find one good photo from the other day... so to break it down. This is an injector with out the spacer and o-ring here is a out of focus picture of the metal spacer and on the felt is an injector with the o-ring and spacer, toe one on the right just has the spacer on it. I did have 2 of the rail side o-rings and spacers get stuck in the fuel rail, and used a very small allen wrench to get them out. we cleaned the injectors with sea foam, and cleaned the injector port on the engine with carb cleaner. dads MJ no longer has a leaking fuel rail or a tapping engine.
