Question

Okay heres the problem. the car wont start when i try cranking it. Unless i put my foot on the gas at the same time as im trying to starting it. Once i let off the gas the car turns off. So car i've takin my alternator, battery, igntion control modaul in to have it tested. They all passed. I even tried a brand new tps senor. didnt make a diffrence. Anyone have any other idea what it cold be. befor the this happend the car has been running like a champ.

was the tps sensor set with an ohm meter or was it one of the ones that didn't need to be,because a bad tps that isn't set right will cause this because it helps to govern the amount of gas that the engine receives,another thing that will cause this also is a bad oil pressure switch on that car ,you might want to check that also,good luck.

idk im not sure i had just bought it cause the guy at the store said he had the same problem happening to him so i took his word and bought it. but i same thing car didnt work. i was told you need to reset the car computer so it can pick up the new tps sensor. i didnt get it. What should i do now.

Answer 2

Check the vacuum lines and check the air inlet downstream of the air filter- make sure there are no cracks in it. You can put a light in it as night and see it shine through any cracks.

Answer 3

try the mass air flow sensor it is located near the air filter box
