It is probably where the exhaust manifold meets the tail pipe but it will be in front of the catalytic converter.

Can you clean out a air check valve before deciding to replace it


If you get it apart then you may be able to clean it . A good carbon dissolver may do the trick but I would not waste my time as it may not seal properly when you have finished.. It may have a broken spring inside that you will not be able to replace as well.

Where are the coil injectors located in the engine


The fuel injectors are under the air intake plenum on the fuel rail. I do not intend to be mean, but if you do not know enough about an engine to know where the fuel injectors are located, you probably should not attempt to mess with them.

Removal Procedure

Caution: Allow the engine to cool before servicing the secondary air injection AIR system in order to reduce the chance of severe burns.
1. Remove the clamp from the check valve.
2. Disconnect the AIR hose from the check valve.
3. Remove the check valve from the left side AIR pipe.
4. Remove the left AIR pipe from the exhaust manifold.
5. Before replacing a check valve, test the valve for proper operation.
5.1. Install a vacuum pump to the nipple side of the check valve, AIR pump side.

5.2. Pump the vacuum pump to 10 inches Hg and observe the gauge.

5.3. Replace the check valve if the vacuum bleeds down to zero within 5 seconds.


Installation Procedure

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

1.Install the check valve onto the AIR pipe.
Tighten the check valve to the AIR pipe to 23 N·m (17 lb ft).
2.Connect the AIR pipe to the exhaust manifold.
Tighten the AIR pipe to the exhaust manifold to 20 N·m (15 lb ft).
3. Install the AIR hose to the check valve.
4. Install the check valve clamp.

How does the injectors come out


You didn't say what kind vehicle it is but in most cases it will involve removing the upper air plenum along with intake air tubes from air cleaner. Locate the fuel rail and remove any hoses over it. Take out the hold down bolts for the rail and GENTLY pry up on the rail and injectors. remove the injector from the rail and install the new one. there is usually some type of keeper holding the injector in depending on what kind of vehicle it is. reassemble the engine in opposite order.Good luck!

How to replace fuel injector


in order to replace any injector on a millinia 2.3 miller motor (super charged) you need to

1) remove battery
2) remove battery holding plate (requires 7 10mm bolts keep them together)
3)next use a pair of vise pliers to move the clamp on the second air cooler it is locate right by the battery location.
4) remove the two 12 mm bolts on that same air cooler located on the bottom of the air cooler (one is right torwards the front the other is torwards the fire wall)
5) remove the tention clamp on the most front air cooler it looks like a small radiator
6)remove the three 12mm bolts in the front of the front air cooler (keep together!)
7) take off the throttle cable from the throttle body (do this by manually lifting up on the half circle looking cable pully it should be bronze or gold in color)
8)use a 10 mm socket to remove the three holding harnest you will see (very obviouse follow the throttle cable)
9) remove the vaccum lives from the intake manifold (thats the big silver piece you have been looking at with all the componets and vaccum lines attached) ALSO TAKE PICTURES TO ENSURE ALL VACCUMS ARE RE ATTACHED IN RIGHT PLACES
10)remove both air coolers (front one and the side one located by the battery area)
11) remove the 14 12mm bolts retaining the intake chamber (also know as the dynamic air chamber)
12) un hook all electronics (o2 sensor blah blah basicly if its hookid up unhook it dont worry about the pic for this each plug is differant allowing it to only hook up to one plug)
13) remove top intake chamber (will be kida tough do to the fact it is probably the first time being removed since its build
14) take a pic of all vaccum lines under manifold making sure to repair any cracked or broken ones (very important to do that many of the t junctons will be broke your motor should never sound like its hissing )
15) to remove the injector pick the one that is suspected of failure and on that side of the fuel rail there will be 7 phillips screws holding a plastic cover on the the fuel rail (this is the electronics of the fuel injectors
16) remove the injector by twisting the injector and pulling( very hard to get out )
17) install a new injector (will take alot of preassure to get in )
18) make sure the notch is lined up with the groove on the rail (this ensure proper seating of the injector)
19) REINSTALL IN REVERSE AND YOUR DONE!

Car will not start without spraying fuel into intake cant tell if fuel pump is running is there a reset switch and where is it located its a 1997 eclipse 2.0 non turbo


there is no such reset switch located in the car. First turn your key on and listen for the fuel pump to pressurize the lines. Then check to see if the fuel is leaking from the  filter. If it is you may have got the connection wrong. If thats the case your engine is not getting the proper fuel pressure to run. Hence its sucking air. If that does not work you might have a bad fuel pressure regulator sensor that is bad. Its located by the TBI. Reference a Haynes manual for replacement.
also if you did not fill the new filter with fuel then you have air in you system and engine will not run. so try taking it off and filling it with fuel and then replace it.
--------------------------------------
turning ignition on removes air from fuel lines and primes the fuel system. filling fuel filter with fuel is irrelevent, as lines need to be clear of fuel upon installation. leave ignition on after installation for roughly 30 seconds-one minute. this will prime the fuel lines and remove air and most water from the system. if problem continues, fuel injectors. this is a common problem in 90-92 camaros. if cannot start car, you'll need to replace every injector, as it's not cost-effective to diagnose every injector. roughly 300 dollars in quality parts, roughly 4 man hours of labor. if rough start that requires push on accelerator (try this), run the car with fuel injector cleaner. this should salvage you injectors. if this helps proformance, starting, then for the next 3-4 full tanks of gas, add stp injection cleaner for every tank of gas. be careful, as this does not restore your injectors, but it helps clear away deposits which are common in multi port injectors.

98 S70 cold start


Milethro,

I'm guessing your car has over 100,000 miles, right?

Hi, I currently have a 98 V70 XC Cross Country that was throwing the secondary injector air pump code. I removed the pump (under the battery tray) and it was filled with water. This happens because the check valve sticks open and allows the exhaust water vapor to accumulate in the pump as the air pump is mounted lower than the check valve (located behind engine back by firewall)

If you locate your air pump, just put 12 volts dc to it from the battery to see if it comes on and winds up..........it'll sound like a jet engine taking off if everything is working. Run jumper wires from the battery posts down to the air pump connector.

I removed the pump and freed up the bearings, then drilled two small drain holes in the casing. Works fine now. Also removed the check valve and cleaned. Checked with a MityVac vacuum pump to make sure check valve diaphrapgm wasn't leaking. Okay, just dirty. Working fine now. Do a Google search on the Volvo secondary air injection pump and you will find good info on removing the pump and valve for repairs or cleaning. These air pumps are expensive, so try removing and fixing yours first. Volvo had a bad problem with water accumulating in these pumps. Most junk yards don't have any in stock due to the cost. Most have been removed by now.

My problem now with the wagon is excessive cranking when cold. When I first try to start it, it will crank for 7-8 seconds, then start. If I immediately shut it off and try to restart it, it restarts quickly every time. Wondering if I have a fuel pressure problem? Any thoughts?
