i love your videos. They are straight to the point. Simple and sweet but very informative. Ive been work on a 2005 Kia sedona. When i bought it i drove it home and it needed a tune up so after i did plugs wires and oil change and air filter and new 02 sensors ect. i had a check engine light saying low voltage to the mass airflow sensor and high voltage to the IAC. I accidently hooked the 02 sensors backwards. So i fixed it and after driving it it wanted to hesitate when in drive. sluggish. so i decided to rechecked my wiring and took the intake pleninum off to make sure a.ground was hooked up ect. then it hasnt started since then. i didnt hear the fuel pump going on so i started by replacing my pump then it wasnt getting spark so to sum it up i have basically swapped out every sensor and coils ect. replaced fuel pressure sensor, crank and camshaft. ignition failure sensor and ingnition switch. and ignition capacitor. i tested the crank and cam sensor and they are getting power and ground. and the trigger signal looks good. replaced the battery and coils. but it still wont start. im kinda stuck on what else could be wrong. maybe the compression or broken timing chain. the pcm works cause i get my check engine light after i turn the key. what else could it be. know anyone in washington state that you would recommend to hire so can get some help? im a single mom who works on my own cars better than some men. but im am so frustrated that i cant fix this. maybe someone can see something im not.

odds are you fried the main computer circuits when you hooked up the oxygen sensors on backwards, that would burn out part of the computer. the light can still come on though that's no real test of the computer
