What is your question?
The local auto shop diagnosed the car then replaced the fuel filter, crankshaft sensor, and camshaft sensor. The car ran well for two days, then the same issue reappeared. The shop replaced the sensors again, as they suspect the replacement parts can be faulty. This time my car lasted for a month. Finally, the auto shop told me they could not figure out why.
So, here are symptoms of my car.
1. I managed to start the car initially, now it died completely.
2. The engine cranks but the car will not start.
3. When the key is on, the fuel pump does not prime, and there is no control signal on the fuel pump relay.
4. When I applied 12v to the fuel pump relay control pin, the pump runs and good fuel pressure was tested. I cranked the engine, still no start, only to smell unburned gas.
5. This indicates that the vehicle lost fuel and spark at the same time, and a bad crankshaft sensor seems to make sense.
6. But then what can make the sensor die frequently?
Any help is appreciated!
‘IF’ proper testing has proven sufficient FUEL and SPARK are present - that leaves ‘insufficient’ compression or restricted exhaust flow path.. Unfortunately we can’t put hands on the vehicle nor even take a look under the hood. I will add ALL of the FUSES need to be TESTED !! Fact is - only via proper *hands-on* inspection - testing can a repair solution be reached. Good luck!
