Question about 2006 Chevrolet Express Passenger
Looking at buying an Express 12 passenger. Some model years (according to reviews) have had recurrent problems with fuel injectors. "The cost to repair the Fuel Injectors on the right bank is estimated at $615.00 each for parts and $423.00 for labor for one fuel injector and $26.00 for each additional Fuel Injector. The cost to repair the Fuel Injectors on the left bank is estimated at $615.00 each for parts and $317.00 for labor for one fuel injector and $26.00 for each additional Fuel Injector." Would this be a one-time repair mostly likely or an ongoing problem? I don't mind the buying an older model, but I am concerned. Other model years mention same problem. Would a mechanic be able to tell if this work had been done already?

the part usually runs from 30 to 70 dollars just for the injector. labor differs from place to place with the average being about 100 bucks an hour

IT IS POSSIBLE and has been done. as long as when you disable ign it does not cause pcm to disable injector pulse.when you first cut key on they will spray a shot also. it is also a good way to check for a leaking injector,see if one drips after sitting a while. however if you have fire with a noid light and injector is not hitting it is most likely a bad injector

electronic engine control unit calculates the mass of fuel to inject, not how wide it sprays. It's the type of solenoid that you use. Some have wider spray nzzles than others. An external Fuel pump helps the delivery of the fuel. Also since fuel injectors rely on mass air flows nowadays, you have to have proper mixture coming through. hows your Fuel pressure regulator?
The throttle position sensor reports to the computer the position of the throttle butterfly valve, which the ECM uses to calculate the load upon the engine-but inorder for this to run, you may need an external pump.
Sounds like nothing is being grounded back to the ECM to even give a reading. If your regulator is improper and you do not have a external pump (depending on your model), than check those. If not, Start from scratch.
If you ever lose your way, go back to the beginning_REWIRE!

from the sounds of it its going to be one of 3 things 1) the injector is bad or 2) there is no power getting to the injector 3) bad relay switch.
1) to find out if the injector is good. pull the injector out and with some wire ground one side and touch the other side to your battery, every time you tap the wire to the bat you should here the injector click..
2) if injector is good get a test light and test to see if power is coming out of the wires that go to injector( on some vehicles you have to have the motor turning over befor power is sent through wire, so have someone turn the key while you check the wires with test light)
