Re: Engine rotates but wont start, 96 Thunderbird LX (V8)
Between the post and the replies there is a couple different problems. If the car starts but will not stay running or is running rough, there is a few possible problems. First the cheap and easy fix, fuel filter. Second is the Mass Air Flow Sensor,. expensive but easy. Third is the O2 sensors, takes a little time and is expensive. If it is running rough, it is the fuel filter or O2 sensors. If it will crank and doesn't want to stay running or takes you for a thrill ride, reving and dying, then it is the MAF most likely, but it could also be O2 sensors.
Now, if the car will not crank, I am not sure what this is. I have a 96 LX with a 4.6 myself and I am having the same problem. My car does not want to crank during the first crank of the day. Once I crank it that first time, it cranks fine everytime after that. Now, if I use starting fluid it cranks right up. I believe it is my MAF sensor, but I am not sure. I have an intake and a straight pipe exhaust system. I have checked all the plugs, wires, coils, injectors...seem to all be good. I have replaced all 4 O2 sensors, the fuel filter and the MAF sensor. If anyone has any suggests, please let me know.
