Q: I just replaced my crank and cam sensor and car still dont start

asked by on

I have had an issue getting my car to start i have checked fuel pressure and codes i got a code for crank sensor. I replaced both the cam and crank sensor and car still will not start but if I unplug the crank sensor it starts up and runs like crap. I can not figure out what to do next.

My car has 91000 miles.
My car has an automatic transmission.

You should check to see if your vehicle has jumped timing. Have a mechanic verify that the camshaft timing did not jump after scanning and looking at the crankshaft sensor data to verify it is giving a signal. If it is giving a signal, then the cam and crank signals are way off and causing the wrong ignition timing. If you need to have a local expert come check this problem for you, a certified technician from YourMechanic can come to your car’s location to diagnose the hard starting issue and pinpoint the correct fix.
