Sounds to me like a partially clogged in line fuel filter or a weak fuel pump. Check your fuel pressure with a gauge up by the intake. Any shop can do this for you at little or no charge if you do not have the tools needed. Crank/cam or ignition modules most of the times either work all the time or don't work at all.
MY 03 ALTIMA HAD THE SAME PROBLEM I HAD TO REPLACE THE CAM SENSORS AND THE PROBLEM WAS SOLVE
we had the same problem. we changed the Crankshaft Position sensor, and also the camshaft position sensor. changed ignition coils, and the module under the ignition coil, and still had the stalling problem. an auto mechanic bought it from us and he discovered all that it was was a pinched wire under the ignition module.
There are countless different causes of an engine not starting, but in general, if the engine is receiving fuel, has ignition and compression, it will start. Begin with the basics. Next time it won't start, try a little starting fluid. If the engine runs briefly with starting fluid, you have a fuel delivery problem. Then go on from there. The only way to find a problem like that is to break it down. Check your Cam Sensors sometime they have a loose connection, your engine has 2 sensors a primary and secondary if the primary is the problem your engine wont start if its the secondary i will start but will run rough
O2 sensors are located on the exhaust manifold, the exhaust pipes, or both. Sensor is located on the exaust pipe in front of the fire wall. RV
No, the filter can not pump. It is a filter.
check the wiring goig to the crank sensors and check and see if you can adjust the gap on the outside sensor maybe its not properly connected
sensors for what? The engine has sensors as well as the brakes, steering, air conditioning and numerous other systems. You need to state your specific problem so that you will get an answer.
there is not a ignition module on these like earlier fords, no distributor-cam and crank sensors deliver information to the ECU and it determines spark by the feedback from these sensors. the ECU is located directly above the drivers feet, behind the panel.
An engine may have one or more knock or detonations sensors in the block. The sensors use piezoelectric materials to detect vibrations in the block. If a certain vibration known to be caused by pre-ignition is detected, the ECU can take action, such as reducing ignition timing advance.
timing is adjusted by the ignition module and feed back from sensors
Usally on the rear manifold rear top of engine. You should be able to see the sensor wire from the brain box going out to it.
