Car starts up then stops or what does it cost for ignition coils?

depends on how easy it is to get to, i had a coil co out on my 5.4 triton and their so hard to get to the mechanic charged me 50 just to put in(unscrew 1 bolt and unplug the connector).so if the coil for that car runs about 104 u'll probaly pay 154 are around that number.
