Pitfalls of replacing fuel injectors?

Lube the o rings.聽

That's just good general life advice right there.

Is this the kind of high-pressure system that you need to take care to not inject fuel into yourself through your skin? If so, probably be sure you don't do that...

Especially in a foreign car. The fuel rails in my Mustangs were pretty easy to get to.

It can be a pain to get at stuff on the backside of any聽transverse V6. 聽 One thing that's universal among auto makers is a total disregard for ease of service. They only care how fast they can put it together the first time.聽

馃憤聽I used to have a Dodge Neon (POS) that you have to unbolt the engine just to replace the serpentine belt. I kind of think they engineer them on purpose to ensure work for their dealer service departments.聽

True but in my case they were all V8's: GT, GT500, and BOSS 302.

I laughed and聽now I have to put a head gasket on my daughter's 4.6l Ford. Guess I'll pull the top end off this weekend.聽

Ugh! If it鈥檚 an f150 like I have, it looks like you鈥檇 nearly have.to pull the cab off to get to the head.

No, they just don't care whether it's easy or not.

The two pitfalls that come to mind are pinching an o-ring or heat soak. A little lube聽will prevent most pinch risk. Heat soak depends on the motor design and how many聽miles. The electrical connectors are often brittle and crack/crumble when removing. It鈥檚 usually the lock mech that cracks and then the continuity is suspect to fail.聽

Back in the 80's, Plymouth/Dodge advertised that their Horizon was engineered to allow trouble free maintenance. They lied!

LOL!!! Back in the days when I ran a parts territory I would laugh at the techs screaming about how damn hard it was to service so many of the vehicles of the last 30 years.

Always praising the 50s and 60s cars. "Back then they were simpler, easier, and had room to work on 'em!!"

I feel for them. I'm a big dude with really big hands, and there are many things that I can't do because of those hands. It's why I hate working on cars.聽

I remember in 1983 opening the hood of聽a new Toyota and not being able to see the pavement anywhere. I knew that I was pretty much so out on working on any new car engine. I can keep to things like brakes, (as I did this very weekend replacing the brakes and rotors of my daughter's Ford Fusion), and exhaust. I put shorty headers on my 2008 Mustang GT which was difficult enough to get me to hire someone to put the long tube headers on my GT500.聽
