So i gave hyundai the go ahead to install the new fuel pump, they fitted it, then told me everything was fine, i fetched it and the next day my wife is driving home and the car dies. this time it wont start. So we get it towed to hyundai and they drive it around with the monitoring computer attached and nwo they tell me that it is the ECU.
The SM tells me that te car is fine and then all the lines drop and the car dies. Today they are sending the ECU for testing.
i have no fait left in this dealership.

Its sad to hear that you are still having problems. Anyway, sooner or later they will find what is wrong and fix it for good, but remember to claim back (refund) all the expenses done due to wrong diagnosis. For example, the new fuel pump apparently was not at fault and it shouldn't had to be changed, because the problem persists. Also, the towing expenses can be claimed. I don't know how consumer laws work where you live. Around here, you can claim back any and all expenses made due to bad repairs as a result of wrong diagnosis.
Back to your car's problem, it seems there is an intermittent fault that causes the engine to die or run bad (rough idle). This sounds more like a bad contact (corroded or dirty plugs in wiring harnesses) or a loose contact somewhere in a sensor or circuit board. I know this is not much help and if it turns out to be the case, such problems are the most difficult to pinpoint and properly diagnose.
Let us know the outcomes
