Well for starters, you need to diagnose the problem before replacing anymore parts. I say this because you mention both the fuel pump and sensors dealing with the ignition system which are 2 separate main things. Basically it takes 2 things to make an engine start, fuel and spark at the spark plugs. You need to narrow down what is missing because it seems since you replaced sensors dealing with spark and then you mention the other need fuel. I'm not sure as to where to start to help until whatever is missing is diagnosed and then find the cause of the loss. There are a couple of things you can check. Below is a picture of the relay box in the engine compartment. With the help of somebody put a finger touching both the fuel pump relay and the EGI main relay. While touching them have somebody turn the key to the "on" position (no need to try and start). When the key is turned on you should feel a "click" inside both of those relays. The fuel pump relay will click for about 3 seconds and the click again to shut off. The EGI main relay should stay on. If both seem to be fine you need to make sure of the fuel pump gettting "juice" and for power to the ignition system like the coils. You can get to the power/juice wire at the fuel pump pretty easy. You can access the connection at the fuel pump by lifting the lower part of the rear seat. Once the seat is lifted you should be able to see a part in the carpet that is cut to be able to lift the carpet up and access the plate covering the access to the fuel pump and/or the top of the fuel tank. Using a test light, check the green and yellow wires at the fuel pump. You should have power at those wire when turn the engine over or if the key is just turned to the on position you should have power there for about 3 seconds. To begin checking for spark or power to the ignition system you need to make sure you are getting power to the ignition coils. The red and white wires at the coils are your power wires. Check those. Also you can check the power at the fuel injectors. When the key is turned on or when trying to start, you should have power to the green wire at each of the fuel injectors. You should have constant power/juice at each of the fuel injectors. This is where I would start to narrow down the loss. Start here with these tests and let me know how the tests come out by replying/commenting here or you can email me directly at [email protected] ith what you have found out. Once the first tests are done and I know what the results are, we can go to the next step with a couple of other tests to figue the problem out. If one of the relays don't "click" then you have a possible bad relay. The EGI main relay is a common thing to go as well as the fuel pump relay. Don't mind helping and there is no cost to you for it but I don't want to tell you to start replacing parts until the problem is located. Hope this helps get you started.
My 03 Serento was not getting juice to fuel pump. The fuel pump connector was cracked. You might look there.

Does it cranks when you turn on the key to start.-------- If its not cranking then get the coil and spark plugs checked.-------- Also is the fuel pump coming on when you turn the key on.-------I agree fuel pump is replaced, but is it coming on when you turn the key to on.If the fuel pump is not coming on then get the fuel pump relay inspected in engine compartment fuse box under hood or give direct 12 volt power to fuel pump and turn on the key and see , if fuel pump runs or not.--------- ----------- when you start the car, does the starter gets power, test it with meter. Test the voltages to battery, starter and alternator.--- If battery is weak car will not start, if battery connections are dirty or loose car will not start.If battery to starter connection is loose car will not start, if starter is weak, the car will not start.If fuel pump is not getting voltage the car will not start.-------- So once you confirm that battery, starter , fuel pump all are getting power and all are working, then get the coil pack and spark plugs inspected.This will help.To confirm where the problem lies.Thanks.Helpmech.

p0560 is system voltage problem. open or short between the battery positive and the ecm.CHECK ALL FUSES. dosnt matter what they are labeled under dash and under hood replace any that are bad and retry to start. no start then check voltage to ecm grounds to. i dont have a wireing diagram to give you but for a small fee or free the dealer can make you a copy.make sure all the wires that go to battery terminals are not corroded and are making good contact [verified with volt meter]. if after all checks ok then replace ecm. as a side note i havent had to change one ever.
Testimonial: "Thank you for the help. We will continue to check all fuses and wires."

Hi. First of all, thanks for the help. Let me start by identifying all parts replaced so far (my dad started buying parts like crazy)
- Fuel Pump
- Both coils
- Cam and crank shaft sensors
So far, I disconnected the plug that connects to the fuel pump and, on the male plug, checked wires green and yellow green for power with a test light. Light came on when the ignition was set to the "on" position, but stayed on indefinitelly (not 3 sec as axpected).
Then, checked both relays and both seem to be "clicking" like they are supposed to.
To be sure about getting a spark, one of the spark plugs was unscrewed, put back in the sucket, and while making contact with the engines block, the engine was turned over. We were able to see a strong spark.
Still tha car won't start. I was told by a friend that it could be that the car's alarm system is malfunctioning. Looked for the car's alarm to disconnect it, but couln't find it.
Any more suggestions???
Thanks anticipated;
Victor
Forgot to ask; even though there seems to be power on the green and yellow green wires at the fuel pump connector, I don't hear any noise nor feel any vibration comming from the fuel pump. Is it supposed to vibrate or make some kind of a noise as it turns on?
email me please so I can send you some tests to do in a PDF. Will be quite a bit on here and would be easier and no there won't be a cost or anything.

SOUND LIKE THE LITTLE MECHANICAL PUMP ON THE BOTTOM OF THE FUEL PUMP IS WORN OUT. THE TOP PART IS THE ELECTRIC MOTOR SIDE OF IT YOU WILL HEAR IT RUNNING. BUT THE BOTTOM MECHANICAL PUMP IS TO WORN TO PUMP.WHICH MEANS NEW PUMP REPLACEMENT.
