from the start, i was driving on the highway got off and my car started to sound like a subaru, changed out injectors and still the same, started messing with the timing no car wont start, i put everything back together the right way and what no (tdc and dizzy on #1) and it sounds like it wants to turn over but when i check the plugs they're wet. and when i take a wire to see if it gets a spark it does, it shoots a yellow spark but it seems faint and it comes and goes im not sure if thats how the spark is or nothing. changed out the ignition module and still the same. could it be the sensor on the dizzy thats bad or what? it cant be the dizzy itself, car would have no spark period, right? i've looked all over the web and just a bunch of nothing, (changed the button, cap, plugs (they r gapped right) & wires) any help is appreciated

sounds like your throttle position sensor is f*****d. test it out. i had similar problems with it. try taking out your fuel pump fuse, and crank the car. if it starts, let it die out. do it a couple more times till it wont start, then put fuse back on. crank the car WITHOUT priming the fuel lines, and it should start. if youre getting spark, its not your dizzy bc the crank position sensor is inside, and that controls fuel and spark, so cross that off the list. if what i mentioned worked, change your TPS. i believe i got mine from autozone for like $27 or something like that. test things out before you buy and replace to see if its your problem, and save you money!!

Good Luck!
