Hi, The one that vibrates And makes the noise is the ECI Main (the big one on the left). then once i pull igt out there is a slight noise coming from the box but does not last long. The shop had left my interior light on and drained my battery could that have anything to do with it? adn i have yet to try and start it without it. I will give that a try..K i tried to start it without it and it will not start.

Obviously the car cannot run without this relay
THis relay is turned ON by the computer.
THe ECU is fed all the time with 12v and a low voltage can have weird effects.Have the battery fully recharged before anything else.

here is my sob story. i own a 2oo2 kia sportage. it runs wonderful, to be honest one of the best vehicles i have ever owned. i purchased it from a dealer after 1 owner, with 6000 miles on it in 2004. now the drama. check engine light came on about the time for insp. sticker, took it to the dealer & said i needed to replace the fuel injectors. i laughed & left. anyways took it to an independent mechanic & poor me, he said almost the same thing. the computer read that both 02 sensors, the mass air flow sensor & all 4 injectors needed to be replaced. so like stubborn woman i did all that. still the light is on, still rejection sticker & still all reads from the computer. it has been reset over & over & over again. what do i do next? any info, help something please. i love my kia but not the money it seems to be amounting to.

..is it possible you have noted the actual code numbers? (rather than their interpretation) . Some codes show as the result of a problem rather than the cause or point to several or all possibilities.
Obviously, you seem to have problem with fuel metering.....and a variety of possible factors has been thrown out. But other factors are not monitored....like the idle air control valve that several owners have blamed on kind of similar occurences. Have you noticed other symptoms or annoyances that could reveal the real culprit ? Please list the actual parts that were replaced.

Okie dokie, actual parts replaced were the mass air flow sensor, 02 sensor, O.E type, and the other one not sure of its exact mane lost the receipt for that 1. Also plugs and wires were changed, fuel injectors were serviced & cleaned by a certified mechanic, and an oil change. I am not quite sure what you mean about actual code numbers so I will just type it to you as I am reading it. P0171 OEM Brand: Domestic-definition fuel trim bank 1 condition Explanation (in short) computer has recognized a rich and or lean condition one bank only. Probable causes 1. MAF Sensor 2. Oxygen sensor defective 3. Engine misfire-repair 4. Fuel Injector problem. P0171 OEM Brand: OBDII no explanation under that heading other than bank 1 and 2.
As for problems my sportage has never backfired sputtered ran sluggish, lost any rpms, burned excessive oil, used ridiculous amounts of gas. I feel it runs just as well as the first day I had purchased the car. I hope this answers some of your questions, if not I will try again. Thx.

OK P0171 is too lean detected....
"In order to provide the best possible combination of drivability, fuel economy and emission control, the ECM uses a closed loop air/fuel metering system. The ECM monitors the HO2S signal voltage and adjusts fuel delivery based it in closed loop fuel control. Changes in fuel delivery will be indicated by the long-term and the short-term fuel trim values. The ideal fuel trim value is around 0%. The ECM will add fuel when the HO2S signal is indicating a lean condition. Additional fuel is indicated by fuel trim values that are above 0%. The ECM will reduce fuel when the HO2S signal is indicating a rich condition. Reduction in fuel is indicated by fuel trim values that are below 0%. The DTC relevant to fuel trim will be set when the amount reaches excessive levels because of a lean or rich condition.
The ECM sets DTC P0171 If ECM detects exhaust emissions reach an excessively lean level due to a lean condition."
NOw since all the "probable" (my version is "possible" ) causes have been dealed with, too lean means once computer has reached the limits, it is still too lean. My first "real" test would be for fuel pressure. I suspect fuel pressure might be low, either pump failure, clogged fuel filter, or failed pressure regulator. Have a pressure test at fuel rail to make or bust this option before searching for anything else; should be 42-45 psi
My second question is about O2 sensors: there are 2: one before the catalytic, one after. it seems the two were replaced, right, otherwise I'd verify that.

Ok i had the battery checked and it was good. where do i go from here do i replace the relay?

Negative. If as you say the relay "buzzes" when the key is off, something must be wrong elsewhere. IN any case, just to be sure, just swap the fuel pump relay and the EGI relay one for the other and see if the same occurs.
By hte way this is not the first time this oddity occurs...but the issue was not solved or the solution not reported...
Anyway, if this "buzz" continues, I'd make sure there are no debris or sand or salt or moisture that have invaded the bottom of this fuse/relay box.

Ok funny thing the buzzing has just came to a halt. Why i do not know. but if it starts up again i will try switching the two relays around. If that fixes the problem what should i do then?

My check engine light just started blinking at me. This happened after filling the fuel tank. Truck is also running very rough since. 2001 Sportage.
