fuel injectors

hmmwv15 · 05-19-2008, 03:09 PM

I think one of mine is leaking. I can see gas leaking very badly from something, and I'm 99.999% sure that it is a fuel injector. This is my first fuel injected engine, so I really have no knowledge on how exactly to take it apart or what I should expect, how long it will take or what to replace. I could just jump in and start dismantleing things but I'd rather have some ideas on how to do it and make sure that everything goes back in place the way it should. I would appreciate any advice.

Best option is to pull all of them and send them off to a shop to clean/rebuild/balance:

While removing, I snapped off one of those black plastic things that cover the tip. Do I really need it because I have ordered all the gaskets and o rings I need for all four injectors. If I do need it, does anyone have a spare fuel injector I can buy for cheap?

I had the same situation (broken pintle cap) and was told it effectively made no operational difference. However, I went ahead and sent all four injectors to Witchhunter.com to have them tested and cleaned (150K miles). Well worth the money and especially quick turn around. Sent them on a Friday and had them back in the rail on Thursday. Included in the work are all new seals and pintle caps.

hmmwv15 · 05-21-2008, 06:52 PM

so that was about a week right?

hmmwv15 · 05-21-2008, 06:54 PM

Reason being is that I am registered for the SE4RJ (south east 4runner jamboree) and it's in less than two weeks. I am struggling to get this thing going by then.

ahickman · 05-21-2008, 07:01 PM

Yeah, I was worried about the turn around time too. I chose Witchhunter based on the number of positive threads in this forum in addition to calling ahead and talking with them. I sent them USPS and had them returned USPS which seemed risky, but worked out well (less than a week in total). You might pay the extra for expedited shipping both ways if you are worried? Call and talk to them if you are unsure. Very friendly and informative. I am getting ready to ship off the six from my Runner.

I may have to do that, just have to save up first.

rdlsz24 · 05-22-2008, 01:35 PM

A rebuild kit should include the caps. This one is a good deal if you are only going to refresh them and not have them cleaned by Witchhunter, etc:

hmmwv15 · 05-22-2008, 02:15 PM

wow. paid $14 at O'rielly's for their rebuild kit which only included all the rubber o rings. no new pintle caps or filters. I guess I could return them though...

chuggins143 · 05-23-2008, 06:27 AM

...just as a data point, a whole new injector from VatoZone is only ~$50... now that's not a Bosch, they are like $300 each. Shouldn't make any difference if it'll fit in the hole.
Good luck!

Yeah you get them quick too. I have ordered two kits from him. One for the '94 injectors I sold and another for the '88 injectors I have in my truck now. Just make sure you get the kit that is right for your truck. He has another auction for before '88 since that is when they changed.

hmmwv15 · 05-23-2008, 09:39 AM

Yeah I don't necessarily have any money to spend on fixing it in such a short amount of time anyway.

hmmwv15 · 05-24-2008, 02:44 PM

Well, I swapped injectors with someone local and got them in. Tried to crank it up and it acted like it wanted to start at first, then all it did was turn over. I'm about to set fire to the whole thing and watch it burn to the ground so I won't have to worry about it anymore... Anyone have any suggestions? I think my fuel pump went out or something.

4Crawler · 05-24-2008, 02:51 PM

Try the fuel pump test jumper:

hmmwv15 · 05-29-2008, 03:30 PM

Fuel pump I had to rig up a manual switch to get it to work, getting fuel pressure and spark, still not cranking....Who wants to help me push it off a cliff?

I think I'll just start saving for an 85 engine and wiring harness so I know everything is stock...

pcmentor · 06-02-2008, 11:59 PM

I thought my #1 injector was leaking so I dripped some light oil down it while turning it back and forth. Seemed to work. This must be irrelavant since the o-ring is at the top not the bottom.

hmmwv15 · 06-04-2008, 04:14 PM

Can ANYONE give me any tips?! I'm getting fed up with this thing and want it fixed so I can drive it! PLEASE!
