Pesky fuel injector connectors

[Jason]

I'm sure I just need to put some muscle into it but the fear of breaking the fitting is prohibiting me from pulling off the electrical connector for the fuel injectors.
I found out that I have a broken exhaust manifold stud. It is the one right next to the firewall. Great......nice spot.
So, I need to remove the intake and exhaust manifolds and hope there is enough stud left to extract. I am the point of removing the injector connectors and I don't want to break anything.


edit for question.

Any tips on removing the connectors?

Thank you.

Not sure how different the YJ 4.0 is from the TJ 4.0, but I leave the fuel rail and injectors on when disconnecting everything. I disconnect the fuel line coming in. I find that far easier if you're taking off the whole intake manifold anyways.

have you removed the wire retainers?
then spray em with a little lube, and they should wiggle right off

I'm one of the only Jeepers I know that bought a 4cyl. You have traveled with me up the 18, remember? Painful.
An injector is an injector Isn't it?

The 2.5 and 4.0 injectors should be the same. See if you can disconnect the harness instead of each injector or vice'-verce'. A bit of WD-40 for an hour works well to slick up stuck connectors.

Oh yeah, I remember that painful trip up the hill! Made me glad I had the 6-cyl.

Well? Did you get it fingered out? How's it going?

The connectors were easy after I decided to grow a pair. I just wiggled them back n forth and they popped right off. Now to deal with the broken stud.

I saw an episode of Muscle Car, within the last few weeks. They showed a few ways to extract a broken bolt. Both with some of the stud still sticking out, and with it broken off inside. You might want to look on their website, for some tips.
