Hello guys I recently changed the fuel pump (friday this week) because of fuel pressure. When I completed the job, the car started right up. I drove it around for about 10 Miles and the SES light came on. When I scanned the codes, P0011 and P0021 came up. Now I have tried to do my research but there are just too many possibilities and I haven't found one with my symptom. Through reading around people have said the camshaft sensor needs to be replaced, I have no problem doing it, it is rather simple. Infact I had a Mercedes which would do the exact same thing and all that was needed was a camshaft and crank sensor and presto! No more hardstarting, the benz was fine.... Back to my car, the car hardstarts, I have to crank it for longer than usual the first time and it will start. After running the car however, once I shut it off it WILL NOT turn back on for another 15mins. What should I do. Variable timing solenoid is working....


I also have a tapping problem I am thinking it is lifter noise.. video below


Thanks guys

 

Have you checked your oil lately? Sounds bad.

 

yeah, my oil is clean, just added a lucas oil additive and levels are far from low

 

As far as your ticking noise def sounds like a lifter, try and use a stethoscope to isolate the sound before you start tearing into it. Your hard start and shutting off issue is most likely your crankshaft position sensor, common problem with Nissan and infiniti.

 

Once I isolate the sound and confirm its area, should I reshim the lifters? I assume they are auto adjusting so I can't do much orther then shim. Crankshaft is bank 1 correct? Below the TB?

 

BUMP .. please help want this damn thing to run perfect already

 

Is there no fix for this? In dire need for help!

 

I had those same codes on an OBD from autozone. The dealer's scanner (i have an extended warranty) called for timing valve solenoids and both O2 sensors to fix the problem. Never touched the camshaft sensors. Shortly after i had ticking noises, CEL coming on.....then i learned about the oil consumption and low oil causes havoc in the engine bay.

 

I know the driver side timing solenoid works not sure about passenger though.... Will have to check that and O2 senors...hmm i did see that somewhere. Thanks for the advice. I'll check it out

 

Problem still not fixed. Don't want to head to the dealer especially with the risk of the car not starting again. Solenoid is fine, so are the O2's. Anything??

 

Evening BUMP! Need help please! Car doesn't have a good throttle response... makes a sucking noise when i give it a quick 1-5k rev and chokes on its way up... slight shake too
