Fuel Injector Specialists - Fuel Injectors do NOT wear out!
Bad Gas Mileage?       Hard start?           Rough Idle?
   
         Burned up/clogged Catalytic Convertor?
    

You have a pretty good guess as to the cause (bad FUEL INJECTORS), but now what do you do?

The "Quick Fix" would be ANY NUMBER OF CHEMICALS -- Techron, Lucas,
Injector Sting, Gumout, Sea Foam, etc. etc.

So, you tried a bottle or 3 of these "cures in a can" and things didn't improve a bit.  Or more than likely (as we know all too well here at FIS) your engine is running worse than ever, and now there is a strange noise from the gas tank area which sounds like the fuel pump going bad.

Right on both counts!

You see, too much injector cleaner can VERY EASILY dry out the synthetic rubber seals throughout your fuel system -- the NUMBER  ONE cause of engine fires!  And those deposits which are loosened, but not dissolved, continue through the fuel system and clog the injector filter and pintle orifice(s) -- a spray nozzle which is much smaller in diameter than a human hair!

And as an additional "bonus", these chemicals will scour clean your fuel pump bearings (yes, they have bearings).  Added to the fact that most gasoline has added ETHANOL -- a form of alcohol -- and you see why shops replace LOTS of fuel pumps prematurely.  Most with less than 85K miles on the vehicle.


 



So, what Kills Injectors in the first place? 

Three things:

1)Bad internal wiring -- (the resistance increases, or short circuits directly to ground, usually caused by vibration, heat, and in some cases, poor design).

2) Water in the Fuel -- the results of which (RUST) are deadly.  Nothing in the world rusts quicker internally than an injector; they have absolutely no coatings or special metals to resist water.

3) Heat soak --  The PRIMARY reason for clogged orifices and filters, bad spray patterns, low fuel flow, and inadequate penetration.  Heat soak is when you drive the car, shut it off, then the little bit of fuel left at the tip of the injector evaporates (almost, that is, leaving behind various chemical compounds), and the process repeats itself over and over for thousands and thousands of miles.

A good example of the end result of heat soak is to look at the baked-on crud on the inside of an oven which hasn't been cleaned in a while.  

The only way to avoid "heat soak" is to NOT DRIVE THE CAR!  Or not use the oven!

Our 25+ years of experience has shown us (and has probably shown you also), that chemicals only perform adequately in FUEL SYSTEM MAINTENANCE.  To keep things as they are.  And maybe to help a bit in dissolving gas tank water in cold weather.






So what to do instead of chemicals?

Remove and replace the Injector of course, and basically you have 3 options:
 
1)  New from the dealer. (Bring your wallet.  Average price is $135 each, but they are the ONLY source for an exact replacement.  If they can still get them, that is.)

2)  New from your friendly local parts store, who does NOT stock BOSCH, DENSO, PICO, SIEMENS, KEIHIN, DELPHI, HOLLEY/WEBER, JECS, etc.

3)  Used from your local wrecking yard.  Nothing like trading one bad injector for another!





Well now there is A FOURTH OPTION!!

As we noted in our company motto above, injectors DO NOT WEAR OUT!

Injectors are designed and manufactured to cycle (open and close) perfectly for over ONE TRILLION CYCLES.  That is "Trillion" with a "T!"  About 375,000 miles.


      WE HAVE BEEN SUCCESSFULLY (over 90%) rebuilding injectors for
                                       over 25 years!

      Worldwide, over 5 million injectors and counting, in over 50 countries!


        Here is what we do:

     1)  LEAK TEST your injectors at 3 different pressures.
        2)  Check the injector RESISTANCE at pull in AND hold in currents (a 
                test procedure unique to our company).
        3)  Check the SPRAY PATTERNS of your injectors to make sure they
                meet manufacturer specs.
        4)  We FLOW TEST for correct injector VOLUME.
        5)  We remove and return old parts -- o-rings, seals & filters.
        6)  Injectors are then ULTRASONICALLY CLEANED as many cycles as
                needed to return them to as-new condition.
        7)  Injectors are reassembled with top quality parts (nothing Chinese
                here; we prefer QUALITY!)
        8)  Spray pattern and volume checked and noted again.
        9)  Injectors are sealed and returned.
       10) ADDED BONUS:  BEFORE & AFTER pictures included, so you know for
                sure what you are getting!


       

     Introductory offer:  $25 per injector.


     We are local to Denver, Colorado and the surrounding area.  We service
repair shops and individuals who can remove their injectors and want to save
major $$$.
     All of our injector service is guaranteed for the life of your car.  If, during testing, we find that one or more injectors is bad (rust, wiring) there is NO CHARGE FOR TESTING THAT INJECTOR!  And you still get the pictures!


         We now offer flow testing, at a nice
          price of only $5 per injector.  


     This includes new top O-rings (to prevent leaks when reinstalled), and more importantly, PICTURES of volume, pattern, and penetration!  A killer deal!

     Think those RC or injector dynamics injectors flow right?  Let us test them and SHOW YOU while you still have a warranty.
  
     We also have approved local Denver shops which will remove and reinstall your injectors (charging you labor only).

     You can drop off injectors directly to:
              
                      INTERMOUNTAIN MUFFLER AND RADIATOR
                                 2500 Federal Boulevard
                                     Denver, Colorado
                                       


     You can also send your injectors to:
     
                                   4996 Parfet Street
                          Wheat Ridge, Colorado 80033


     Talk to us before you do.  We can help in diagnosis, and we have
many used injectors in stock. 

  


      
     Sorry my friends.  We do not service
               DIESEL INJECTORS.

    Some years back, we invested large $$ in specialized machinery to clean and test diesel injectors.  Turns out, the vast majority of these injectors are killed by poor design (Internal cracks), not dirt.  Super high pressure, vibration harmonics from diesel combustion, diesel fuel affinity for water, etc.,and you are lucky to get 80,000 good miles (emissions and power) from these injectors.

    By the time internal parts are replaced with quality components (nothing Chinese in other words), and super precise torque values are maintained, etc., we were only about $25 away from brand new injectors. 

     Prices on NEW Diesel injectors (Duramax, and the like) have dropped dramatically.  So fast, we can't keep up -- check the internet.

     Our friends at CENTRAL MOTIVE POWER, 6301 North Broadway, 303- 428-3611, can test diesel injectors for you if you want.  But like us, they do not rebuild them.  They are an excellent source for Diesel injector pumps, however, both testing and rebuilding.  They are a good source for injectors for the big stuff -- Allison, Cat, and the like.

      No anonymous answering service -- talk to the techs themselves!

      No injector service telling you not to call and check on your injectors because they are too busy.  (You guys know who you are.)

      No E-Bay injector service  trying to be cheaper than the next guy by $1.00, then throwing finished injectors in a box, and there you go.

      No report which has various "good, bad, or acceptable" boxes checked, leaves you guessing, and includes some incomprehensible response and dynamic variance figures only to impress and confuse you.

      We give you pictures of FLOW, PENETRATION, VOLUME AND PATTERN, both before and after.  (No photoshop is used here.  Or needed).

      You get the truth.

      Each or our techs has been certified and recertified ASE with an average of 25 years experience each.   They don't like "do-overs."  We know you don't either!
