I looked in the DIY section and tried a search to no avail. If I overlooked something obvious I apologize.

Are there any threads on here showing how to replace fuel injectors (mines a 96 1500 4x4 5.2) with pictures?. I just got a set of eight rebuilt injectors in the mail today. After 200,000 miles I figure the truck has earned them.

And if I can increase my MPG by even 1 MPG after new injectors they will pay for themselves in short order.

Thanks!

 

This video may help..

 

I used this place. This guy has really good service. And for the money I thought it was worth it. They replaced all the filters and Stems in the injectors plus clean them and flowrated them for $16 a piece.

Injectors either work or they don't. Replacing them "just because" is spending money that doesn't need to be spent.

What people don't realize (and I've covered this many times) is that if injectors aren't being upgraded, then get an ultrasonic cleaner with a bed large enough to hold an injector or two. Use mineral spirits for the cleaning agent and run the injector(s) for a cleaning cycle. The price of the ultrasonic cleaner, and cleaning agent, is much less than buying a complete set of injectors.

In the event an injector is bad, which can be determined via an Ohm test, just replace the bad injector.

Also, remember to replace the upper and lower o-rings along with installing them using a light coating of oil. Doing so is cheap insurance and will prevent a fuel leak and/or subsequent engine fire.

 

Thanks for everyone's response so far. I just figured after 200,000 miles on the engine a rebuilt set of injectors might help/can't hurt. I'll have just over $100 into this project after I return the old injectors as cores. Hopefully I'll get time to swap them out over the next few days, and then we'll see what (if any) improvements come about in driving, idling, and mpg.

We're planning on taking the truck to Alaska and Canada this summer (starting from TN) and we'll be putting 8-10,000 miles on the truck over a 6-8 week time period. If I can increase my mpg by just one mpg they'll more than pay for themselves.

 

Clean the fuel rails while you're at it.

 

Anything specific I should know about cleaning the fuel rails?

 

@ armynurse when you take your trip if you are in the Sicamous area feel free to stop in for a coffee or a couple of nights stay here at the campground (free).

 

Disconnect it from the fuel line and rinse with mineral spirits or solvent. Inspect for solid particles.

 

and rust holes......
