Just finished rebuilding the engine. The car cranks and cranks. There is no spark, but every now and then one random spark ignites all the fuel that collects and BOOM! And now right when I start cranking, I hear a little metal screech sound JUST as the engine starts cranking. PLEASE HELPPPPPPPPPP!!!

I don't know about the screech but if you are only randomly getting spark I would start there. Are you sure all four plugs and coil packs are good? Wires not junked up leading to the coil packs?

I am assuming you already checked this stuff, but that is where I would start. The problem is it could be anything from spark plugs to ecu to timing to who the heck knows.

 

[sandymuzzkinz]

I checked the coils and they have continuity. I haven't tried the wires yet. I'm leaning towards timing being off, or the ecm being bad. But everything was working fine before the rebuild. The error i'm getting is P1111. Can someone translate that error to me? I'm reading it and its not making any sense. I'm not tech savvy when it comes to cars. :'( My friend is the one that put it together.

What I am finding is an intake valve timing control solenoid. That is just from a google search so you might want to double check it.

I'm wondering if that's just a misreading since my engine has not even once been able to start ever since the rebuild..would that solenoid stop the engine from starting?

I would think so, if it is not letting the intake valves open at the right time it means that oxygen can't mix with the fuel at the right time or as efficiently as it should.

I found a website that is talking about simliar problems as you are having. It may help as well. Check it out.

They are talking about that P111 code and getting the car started. Hope that helps.

That screech you are talking about makes more sense if you read through that whole link I posted above. The guy is talking about how, if after repeated starting attempts with no luck, you may need to re-check your compression and if it is not right....add a little engine oil through the spark plug holes and check compression again. If it is now within spec, re-install the plugs and move on.

That is the advice they are giving. Let me know what you find and if any of that applies to what you are talking about.

Wow! Thank you for your helppp! I will read through this right now.

P1111 NISSAN - Intake Valve Timing Control Solenoid Valve Circuit Bank 1

the intake cam has ctvc, variable valve timing. if the timing is incorrect, yes your car may not start, or will run inefficiently.

however, this is only a circuit code, meaning there's possible bad electrical connection somewhere. maybe it wasnt even connected accidentally. check the connectors and wiring harnesses, look for a broken/fraying/sheered wire. there are most likely voltages to check for this if youre following the fsm. so start at the ivt solenoid, it could be bad. if you think this is a past code, you can clear it with pedal dance or scanner, and see what pops back up when trying to start the car again.

 

[sandymuzzkinz]

OKay so I checked the continuity on the intake valve solenoid and it starts off with continuity but almost immediately drops to 0 resistance...

 

[sandymuzzkinz]

Its most def not an old code lol. I cant seem to be able to understand what kind of voltage drop i'm supposed to look for, and like I said, the solenoid is behaving in a way where there is initial resistance but then it quickly drops to 0.

 

[i68k]

you need to change your cam & cranks sensors if they were failing, the ecu uses a bunch of sensor singals to process the ivt; cam, crank, tranny speed, and thermostat. this is all in the fsm, hope you are using it. the fsm says for your p1111, is either electrical connection or the ivt solenoid itself failing. it also show what pins to check and what voltages you should get, its free download around here somewhere.

 

[sandymuzzkinz]

I changed the cam and crank sensors. The timing belt shows the marks are on the spots that they should be on. But a friend came today and said the cams dont look like they are timed from the positions of the actual cams. He said chains could be off by a couple links in some imports. :/

 

[i68k]

no timing belt, its a timing chain. and yes you can stretch a chain, although its not easy.

even when you line up the timing marks and everything, after some rotations those marks will not line up again for a while, many more rotations, but like said above, as long as they were assembled correctly the first time.

follow the troubleshoot for the p1111 in the fsm, make sure youre reading the qr25de section, not the qg18de sections. you can go check your solenoid, if the solenoid is good then i would question electrical connections/wiring and the internals. the loud screech is probably your belt, make sure your belt is spinning when the motor is running. otherwise it could be like your power steering or something, make sure the fluid and stuff is filled up.

 

[sandymuzzkinz]

Should all the fluids be filled up before i try starting??

 

[sandymuzzkinz]

OKay so supposedly I dont have compression now according to my mom's friend's husband...and he said my timing is off even though the chain links are aligned properly. And thats a new chain.

 

[JudoJohn]

I would guess your timing is off, too. sounds like you may have bent a valve or two.

 

[JudoJohn]

you never said what year your car was. there is a big difference startign in 2003 for the intake valve timing. Nissan has a variable hydraulically controlled sprocket assy. It is difficult to set right. if you didn't reset the variable sprocket BEFORE setting the valve timing, it wil be off.

 

[sandymuzzkinz]

It's an 02. I did reset the variable sprocket at the same time that I timed the timing chain. Is there a way to verify that my variable sprocket did not get messed up?

 

[sandymuzzkinz]

oh yeah I dont have a variable sprocket cuz im 02.
