So yesterday, i drove around all day with no problems, then at like 6 I went to get a movie came out, started my car, it sputtered like a shaking, tried reving it to try and get it to stop, then slowly it died. i started it again, it made a horrible noise in the engine then died. Now wont start at all, its cranking but wont ever turn over had to tow it home. Dont know whats wrong, everything we trying checking gives us nothing, we hooked it up to a computer and it gave us no trouble codes. My buddy thinks it may be the fuel pump, timing belt, or something to do with the spark plugs we changed out a couple of months ago? trying to trade it in for a newer model so dont want to spend money on something that isnt going to fix the problem. Any help or advice would be greatly apperciated.
