1991 All Other Makes All Other Models

I have a 1991 integra 1.8 ls.

i was driving on the highway up a mountain road when the car sudently quit. All the warning lights came on, I was able to pull over. When I started to check the car the next day it would still not start. So I checked for fuel pressure and it was ok about 43+psi. Then check for spark that was ok. Then checked injector pulse with that was ok. The car cranks but does not start. I couldnt check for codes cause I hade taken the battary out to recharge. So im wondering if it could be the camshaft positioning sensor or the crank sensor. What else should I check.

The crankshaft and camshaft sensors help control the cars ignition and fuel system. They also help control the ignition timing and injector timing. I don't think these senors are bad since you have spark and fuel and the motor cranks that leaves only one other thing. The timing chain or belt. ( I don't know which one you have) You don't mention the mileage but from the the year of the car I 'am guessing the mileage is high. If the belt has broken or slipped then the timing would be thrown off and prevent the car from starting. Good luck and hope this helps

Not so on the sensors. The crankshaft sensor can be out but still allow the spark at the plugs. The big issue is the without the reading to the computer the timing is thrown off too far to allow the vehicle to run or else it catches and dies etc. Pulling the battery was not very good as the check engine light and codes would have helped. I take it you tried to crank on it for awhile to kill the battery. Your call but that is the plain truth on the sensors.
