hey, i own a 2002 hundai sonata 2.4, It blew the ecu fuse twice so i changed the fuses, and now i have no spark at all.. I changed the coil packs, brand new, spark plugs, crank, cam, ignition failure sensor and a ecu. and still no start. Fuel pump is running fine.. When i checked the wires going to the ignition coil packs, one is geting power, the other is ground, and there is one more wire that is dead. ( is it supose to be dead or have power running throught it.. I dont know what else to do anymore.. I did check all the fuses and relays, everything is working, but still no spark... Anyone? please? i even replaced this gold box that is located under the radio... is there another computer somewhere? i only found two computers in the vehicle.. Under center console dash, by the firewall.. there is one with 4 black plug connectors and one with one 2 inch that is connected to the airbag computer.. I dont know what else to check or do.. is there anymore computers or relays that im missing? I have the whole dash taken apart so every wire is visible..I know that every pink wire is connected to the ignition system. please some one help me..

I seem to be having the same issue.If you find anything out let me know

yeah, i noticed that the crankshaft sensor was put in backwards, so that code went away, and got spark now... next i changed out the camshaft sensor and misfire sensor and car starts but runs for 5 seconds and shuts off.. any one have any ideas? camshaft sensor keeps poping up on obd2 scanner.. the reason why the ecu fuse was popping was because i had a bad connection/ harness to the camshaft sensor plug.. before all this i kept on having crankshaft code coming up.. so i checked the crankshaft sensor and found the wires cut behind the timing cover.. the belt cut through the crankshaft sensor wires, poping the ecu fuse and not having the car start.. so my dad replaced the crank sensor and out it in backwards.. still no luck.then i noticed the sensor being backwards, so i flip it over and car starts for couple seconds and dies.. camshaft sensor, temp air intake and maf sensor codes are showing now.. im going to replace all 3 sensors and see what hapens..
