Nope. They're on. Seem tight.

Okay. Thank you!

I'll check. What would that mean?

Starting a new topic concerning my retarded fuel injector, supposed upgrade. Everything is back together I think. I have looked for any loose connectors, hoses, vacuum lines, etc. Image posted of what I found, but I'm not sure what I found wasn't already as is. Uploaded audio of truck trying to to start. Never catches, just goes round-n-round. Checked CPS, looks fine. Connection seemed okay. Ran fine before I screwed with it. Just don't understand engines, I guess. Should I just clean the stock injectors and put them back? Really need some guidance here. SPECIAL NOTE: If, like me, you think it would be cool to work on your truck, but, like me, you're a Greenhorn. I highly suggest buying the parts and having someone who knows what the frick they're doing to put them on. This is ridiculous! 474446726_NoteasyVideo.m4a

Well, I got excited too soon! Truck won't start. Turns over fine, but that's all she does. Apparently, while moving all the hoses and crap around I damaged some vacuum lines. I'll try to repair them tomorrow, but I didn't think vacuum lines would cause no start, just a rough idle. If anyone can offer suggestions about what may be causing the no-start, please, please chime in!

Yeah, just had to squeeze the tabs. Other guys on YouTube were using a disconnect tool. I thought I needed one, but clearly, I didn't! I really overthought this whole process.

Okay folks, this job is almost done! I really do appreciate all the advice and direction given. Hopefully, tomorrow evening I'll have this thing 100% complete, leak-free and ready to go! My only worry now is that the larger retaining clips don't serve a purpose now on the replacement injectors as they are a different shape. They are the ones Stankfoot recommended for Renix trucks, so I gotta go with that.

I did find the Dorman clips at Advance. They will have them at 3 pm tomorrow. Even if I grab some O-rings, it will be half the cost of the kit.

Oreilly has the repair kit. https://www.oreillyauto.com/detail/c/standard-ignition/standard-ignition-3-16-inch-i-d-1-1-2-inch-long-plastic-fuel-line-repair-kit/std0/hk7/v/a/2238/automotive-truck-1988-jeep-comanche?q=fuel+line+reoair+kit&pos=2 At $25.00 bucks it's a complete rip off for the customer! Sheesh!

Yeah, they are crunchy and did break. Dammit!!! Looking for a replacement now. If anyone know the part number please share as I have this thing all apart now! Thanks for the help everybody. Finally got the fuel rail off.

Okay. Making some progress. BUT, (see pic) I am not finding any help removing this thing. I don't even see it on videos. I know the fuel line connects to it, but I cannot figure it out.

Yeah, I did have them off. Had taken the pic after I put it all back.

IT AIN'T EASY!!!! I have watched several vids about this and everybody seems to taking off different random parts to get the job done. The 4.0's they are working don't look like mine. That doesn't help me at all. I finally found a vid of a guy working on a '89. Looked mostly like my '88. Looked pretty straightforward, he wasn't taking off so many parts. I gave it a shot, couldn't do it, got pissed and put everything back! I cannot figure out what parts REALLY need to come off to get the fuel rail off. I have two screws at the front of the engine that I haven't seen anyone else remove. WTF?! Looks like they must come off! See pic. I also can't get the injectors loose from the rail. I can get the clips off, but the part that supposedly "pops right off" ain't budging. I do not want to break anything. I have a leaking injector, see vid, so I need to get this done. Is there a source for this job that is simple and straightforward enough for a Neanderthal to follow along. That's what I need. 1370240546_gasspray.mov

Okay, now I'm cornfused and I definitely do not understand the function. However, @cruiser54 seems to have been through this many, many times with no issues and real-world experience holds a lot of weight with me. I do understand that typically, parts aren't added just for looks. But, it is possible that what was thought to be needed in 1988 turns out to be incorrect. Just playing devil's advocate, not picking sides.

Okay, so I plugged the line the and valve. We'll see how it goes.

Thanks for the clarification. Sounds like the way to go.

I'll do it!

Okay, is this the hose/line I am supposed to be looking for? I do get heat in the cab through the defroster. Honestly, I don't know if I get heat from the floor. Don't think I have ever checked. Not in a while anyway.

You are right. If I didn't install it then I would have no idea where I put it! It's rainy here so I have not been out to check it. Just how many connections can be "bypassed" on an MJ? Seems like most of them. 😆

That would be great! Thanks!

Will do!

Okay. Is there a diagram around that I can use to reconnect?

Just want to know if I knocked something loose, or is this just another strange, unneeded part under the hood. I noticed this canister, filter, alien tech while shoving hoses around trying to get the valve cover off. Don't see an open hose, so maybe it's nothing. Thoughts?

Agree. However, all the plastic parts are pealing the clear. Bumpers, pillars, roof deflector, license plate area. It if was just the pillars, black it is, but I don't think all the others would look right. I don't want my wife looking like she commutes from the ghetto! I'll keep looking around.

I thought about black or dark gray, but I thought it might like too much like a patch. Does Acetone remove old clear coat?
