Alright so my serpentine belts were squealing on my car, so i re-tensioned them. I loosened the bolt on the alternator pulley ( i also unscrewed this wire cluster in the ribbed outside casing that was making it hard for me to move the wrench. from the body which looked like it was just a bracket, but now i think it was a ground for the wire but i forgot to screw it back in before i cranked the car do not know if that was a problem) But i got the belt tension nice and tight cranked the car no squeal. then the next day i cranked it and the car cranked but i almost felt a wobble from the car (meanwhile that bracket on the wire is not hooked up) so i cranked it again and it kinda started and gave out i thought the belts were too tight i loosened them and now the car wont start it will turn over all you want it to but will not fire up i cant figure it out. the crank sounds a little high pitched but could be wrong please if anyone know what is going on let me know had no probs from this car except for squealing belts

 

Back to basics:

Does the fuel pump prime? Is there bright white spark at the plugs? Any CEL codes?

 

I checked all fuses no cel lights. There is fuel in the filter and in the fuel return i pulled the spark plugs there seems to be a fair bit of oil on them not a ton and maybe possibly leaking above the plugs which i think in return may have fouled them which in return im going to replace all four and see
