story: i was driving the car on the highway and there was half tank fuel left. before this the car drove FINE. no check engine light. it was losing power so i pulled over and the car manage to stay on but has a shake like if one spark plug wire is disconnected. @ WOT it would not respond but half way it accelerate very slowly and work it's way into WOT. so we tow the car back home. after numberous attempt to start the car this time it doesnt start at all.
CAMSHAFT POSITION SENSOR: rope it to autozone for a free engine scan and it says camshaft position sensor. i bought and replace it for 80 bucks. still no change.
FUEL PUMP: i pop open the DIAGNOS box in the engine bay and put a paperclip in the +B and Fp and key to RUN the fuel pump would constantly stay on. i would attempt to crank it over and still no result so i knew the fuel pump is not the problem.
DISTRIBUTOR: i pull the plug off the 4th spark plug and put the booth end toward a nut on the valve cover to check for spark. i see arching making contact to the valve cover bolt while my friend crank it over so i know i got spark.
air+fuel+spark= RUNS but thats not the case with this corolla.
help?
i want to also mention that there was no overheat issue with the car so this definitely not an blown headgasket issue. one thing odd about this corolla was a few days ago i check the oil and it was bone dry. didnt move the car at all and did a complete oil change. i put 5 qt of oil inside and then check the oil and i was about 1 qt above the line maybe?? does overfill oil prevent car from starting? unlikely...
AIR FILTER is clean.
FUEL FILTER: i took a look down the brake booster and the fuel filter looks BRAND NEW. it's shiny black along with a clean white tab behind it to mount the screw. this car was pass down to me from my aunt so she probably had the fuel filter replaced.
engine will turn over, but wont start.
