Thanks Garry,
I will tray the new CPS first to avoid any further codes confusion.

I replaced the Crank sensor and still have the same issue with the starting.
Any other Ideas?
Thanks

If it's your fuel pump, you can diagnose this way:

Before going to start the vehicle, turn the key to position 2 and hold there for 5 seconds, then back to 0, then repeat 2 more times.

Now try to start. If it starts right up, it's your fuel pump. The sequence I suggested gets the pump to pump up the pressure before starting.

good luck

Thanks Abran,
I tried that already and didn't work for me.
Reading some treads I'm coming to the conclusion that could be a leaking injector.
Anyone can support me on that or knows a way to test for leaking injectors before I take them off.

While it's running you can spray carb or brake cleaner all around under upper manifold in general injector direction. If the engine sound changes you have a leak.

Wow. Sorry about the CkPS, seems like it all the issues were related, But going back and read your initial post, you were getting 1174 and 1171. I had that not too long ago and I replaced all the injectors. Not only the O-rings were loose, it was saturated with liquids.

Please check out my last August and see how I fixed the issue.

Thanks LR03NJ,
I was thinking along those lines... Where you also having issues with starting back then? or just the codes?

Do you have any recent codes? If you still have those injector codes, try using some injector cleaner with 93 octane gas. Thats a lesser evil than digging in there and check/replace the injectors or O rings. As far as we know you have an new CKPS. LOL! So we dont have to deal with that anymore. Cheers!

I finally found the hard starting problem to be a bad fuel pump. Even though it was a few moths old.
Thanks to everyone that try to help me.
