Fuel Injection Service

How much does a Fuel Injection Service cost?

It depends on the type of car you drive and the auto repair shop you go to. Our mechanics are mobile, which means they don't have the overhead that repair shops have. They provide you convenience by coming to your home or office.

What is a fuel injector and how does it work?

The fuel injector delivers fuel into the engine, either into the engine’s intake manifold or directly into the combustion chamber. The fuel injector has an electrically operated gate controlled by the Engine Control Unit (ECU) which dictates when the injector should deliver fuel into the engine cylinder. The goal of the ECU is to keep the air-fuel ratio optimized while the engine load and operating conditions constantly change so that the engine can burn fuel efficiently. It is recommended to clean the injectors every 40,000 to 50,000 km to ensure they don’t get clogged and your engine keeps running smoothly.

When should you consider a fuel injection service?

  • Your engine idles, loses power, or misfires. Faults in the fuel injection system are a common cause of poor engine function.
  • Smell of raw gas or visible leaks. The smell of gas around you car suggests that your fuel injector may be leaking. There should never be external leaks from a fuel injector. If you suspect that your fuel injector is leaking do not start your car as this is a fire hazard.
  • Check engine light is on. Certain fuel injection failures, such as a faulty solenoid, will cause a trouble code to be set in the PCM and that will cause the check engine light to turn on. When this happens, a mechanic will read the codes and test the fuel injector, as needed.
  • Major engine repairs, engine replacement, or long-term storage. Deposits in fuel injectors will always occur given enough mileage. These deposits affect the performance of the injectors from cylinder to cylinder. If you engine is disassembled, or if you are installing a new engine, it’s a good time to service the injectors as well. All injectors have tiny internal filter baskets: servicing the injectors entrails cleaning each injector ultrasonically and replacing the filters, which can be done at a relatively low cost.

How does a fuel injection service work?

Injectors can either be removed from the car and serviced, or be replaced with new injectors. When injectors are serviced, specialized equipment are necessary for cleaning and testing. The problem with the injector will determine whether they should be repaired or replaced. Both options require removing the injector from the vehicle and typically following this procedure:
  • When the engine is off and cool, the mechanic relieves pressure within the fuel rail by briefly running the engine with the fuel pump fuse out.
  • They will them remove the upper plenum on the intake manifold along with any hoses, cables, or wiring that restricts access.
  • Next they’ll remove the supply and return lines from the fuel rail, unlock and remove the electrical connectors to each fuel injector, and unbolt and remove the fuel rail from the intake manifold.
  • The injector(s) that need to be serviced or replaced are then removed from the fuel rail. It’s critical to make sure no debris enter the exposed openings. An O-ring seal usually firmly holds the injector in a finely polished bore in the fuel rail. This O-ring will need to be replaced.
  • Using a new O-ring, the injector is re-installed into the fuel rail. O-rings fit very tight to prevent fuel leaks and engine oil is used on the O-ring to prevent any damage to it.
  • The mechanic will then re-install the fuel rail and reconnect the supply and return lines. The plenum is re-installed along with all cables, hoses, or wiring.
  • Then, the engine is run and the mechanic will carefully check for leaks and road test the vehicle.

Things to keep in mind when servicing a fuel injector

  • Making use of top quality Tier One gas may decrease deposits on gas injectors and extend their life.
  • If an injector issue requires the replacement of one injector, it's most effective remove and service every other injector at the same time. This might involve replacing an electrically failed injector together with an out-the-car cleaning of the remaining injectors. Serving all injectors simultaneously guarantees the injector set will be well balanced and in turn ensures smooth engine function.
  • Do not make use of gas system cleaning compounds, or treatments, unless such products are defined by your vehicle's manufacturer.
  • Cleaning gas injectors in the vehicle is not as efficient as out-the-car cleaning since injectors have small inner filter baskets that must be changed as part of the procedure of servicing a gas injector.

Can you safely drive with a fuel injector problem?

Yes, as long as there is no external leak of gas from a damaged or defective injector, it is risk-free to drive the vehicle. Nevertheless, if the injector is recognized to be malfunctioning, it can trigger engine misfires, extreme discharges or, in the case of a terribly leaking injector, can overload as well as overheat the catalytic converter. Furthermore, gas effectiveness will constantly be reduced if the gas injectors are not functioning effectively.

I wanted to get a pre-purchase inspection of a vehicle I was interested in purchasing from a private seller on Craigslist. I was able to book an appointment on the same day I called, which was very convenient. The mechanic who came out, Waheed, was very professional and friendly. He did an extremely thorough inspection of the car and clearly explained what some of the issues that he was seeing... were as he went. You get a very detailed report as a result of the inspection which allowed me to negotiate the offering price down quite significantly. It was definitely worth it and I would recommend this service to anyone looking to buy a used car. I should note that the pre-purchase inspection typically includes a driving segment, but the mechanic cannot do it if the car is not insured (for obvious reasons). I didn't realize this when I booked over the phone, and I was comfortable with just a visual inspection given the age/condition of the car in question, but if you are particularly worried about the car's transmission or steering I would make sure it is insured so that the mechanic can come and do this part of the inspection.read more

Battery died and had no way of getting it to a shop to get replaced. These guys came to my house within 5 hours of calling and did a diagnostic to make sure it was actually the battery . The tech showed me what the problem was and explained it to me in terms I could understand . When he told me the battery had to be replaced and didn’t even mention that they sell them. I asked if he could do it... and he said yes - Gave me a great price and had it running within an hour of arriving . He also did a 30 point Inspection. These guys are professional, friendly and do it all. Will be my go-to for Mobil mechanic needs.read more

This service is so convenient. The mechanic Mo was friendly and knowledgeable. I had to get my rear brakes replaced and the price was fair plus it was great to have them come to me. I would use the service again!

I recently got my brakes changed through instamek and had an awesome experience. The mechanic was prompt, friendly and professional. The best part was that I didn’t have to leave my house and was able to work from home and not take any time out of my day to go to the shop. I would highly recommend this service!
