Good day.

I've done so many things to that car expecting it to start and still it doesn't want to start. I've actually gotten brand-new 6 coins and has inserted them into that car, I've gotten a new fuel pump, I got a new crankshaft. New intake vanos sensor and camshaft sensor. I also got brand new battery from another working car and still the car won't start. I was also told if the exhaust was blocked that the car also won't start but have not check that. I have also tested valvletronic seems to be working because I used 12 volts to test and it row. Please I'm actually confused I don't know what else to check and what else to do can you please advise me on what next?

Any time I get to this point we need to do one of two things. Seek a second opinion for someone to look at it with you. Or act like you have done nothing to it and start fresh.

So what is the current state of it starting? When you turn the key does the dash light up like normal and the engine crank but it doesn't start?

If so, we need to check for spark and fuel. Then check for codes and see what is active. I am not interested in stored or old codes. Only what codes are currently active.

Then to check for fuel, spray starter fluid in the intake and see if it starts for a second. For spark, remove the plug and connect the coil back to it and hold it against the block and see if it sparks when you crank the engine.

Let me know about each of these things and we can go from there. Again, don't tell me what the result was in the past. We need to do it all again in the event something is different. Making those assumptions is why we are going in circles. Thanks

I started are fresh and got 6 new plugs and change the coils. The car started, idled for a bit then shut off. I restarted it and press the gas pedal but the could not pass 3 rpm and later loss power then shut off. Try starting it again but no start.
Codes I got:

P1554
P1553
P0015
P0102
P0205

Okay. So replacing plugs and coils that all failed on the secondary side got the engine to start. Now it is not starting again. I would test the coils again and see if the secondary side is failed again. These codes all point to an open circuit issue so I am thinking we have a possible driver issue with the ECM. Remind me if you replaced the ECM already or not?

Let me know if the coils are okay and we can go from there. Thanks

I have tested the coils and they are all good even tested them on another car. ECM has not been changed but I inserted it in another car and it worked. Could be that I have a low compression in the engine or one of the shaft has bent?

And also as I pulled out the plugs I noticed only cylinder 4 to 6 fire. Cylinder 1 to 3 did not fire.

I doubt this is a compression issue but here is a guide if you want to check it:

https://www.2carpros.com/articles/how-to-test-engine-compression

Just reviewing these codes and the history on this thread, I hate to say it but it appears it jumped timing again. I see that this basically happened the same way as it did prior and you found that the timing had jumped.

If it did, then we either have a chain issue or a possible tensioner/guide issue. Basically there is too much slack in the chain and once there is tension put to it, it jumps timing and the engine cuts off.

Let me time back the engine and tight the tensioner bolt and see what will happen.

Okay. Sounds great. Before you mess with the bolt, just push on the chain and see if there is much slack. There should be very little. It should feel pretty tight. At least that will give us some idea that we are on the right path. Thanks

I have done it and the chain looks pretty tight, because I was touching it while a turn the engine manually. Set timing and start the car and it runs poorly only if I press the pedal and it never revved pass 3 rpm and later shut off the same way. After 3 attempts with the same thing car won't start and gives car codes p0015, p0102, p0205, p0203 and p1124.

Okay, so if the engine was not starting and you timed it again and the engine started and then did the exact same thing again, you have an issue with the timing chain or tensioners. It is rare but I suspect the chain has stretched and is just not tight enough so it keeps jumping time.

Clearly I am only going off what the vehicle is doing after you re-time it so I would suggest getting another chain and take the one off the vehicle and lay them next to each other. Again this simply from experience and applying that to what this is doing. If the chain is not stretched then the tensioner is loosening when the engine is running.

Great update using that video. Two things. First the metal shavings that you felt is not a good sign. Most likely that is bearing material and could cause some issues but I don't think it is causing this one. I suspect that tensioner is your issue.

I can't say I have ever checked the tension on an N52 engine but most tensioners that I have felt, I could not compress.

Here is a video of someone changing the tensioner and he squeezes the old one and it does not compress at all. Now this may still have the oil in it but even still when he is installing the new one, it appears to have a lot more tension when he is screwing it in. I may have missed it but was that a replacement tensioner or the existing one? Either way, I would get another and compare it. Even if you took that one down to the parts store and just took the new one out of the box and compared the spring tension.

The first start my leg was not on the pedal but the second time it started my leg was on the pedal and it couldn't rave pass 2 rpm then later shot off could not restart again. Tensioner has been replaced.

Another thing, I just noticed is that when cylinder 1 is at top dead center cylinder 2 is also at TDC. Is that a good sign or what?

That engine sounds like it is knocking or rattling quite a bit. Have you drained the oil and cut apart the filter to see how much metal is in it? Drain the oil into a pan and then pour it through a coffee filter to see how much metal is there.

As for the pistons, that does not sound correct. Take a look at the picture of your block with no head. 1 and 6, 2 and 5, 3 and 4 are synced together and the piston will be in the same position but on opposite strokes. So when 1 is coming up on the compression stroke, number 6 will be coming up on the exhaust stroke.

If you have number 1 and 2 at TDC, they will be on different strokes but that is not correct.

Hello, I am having a challenge. I started the car and it ran for some minutes and now it won't start again. No spark on the coil and injector not spraying fuel. I used my test led to check if the trigger wires bring current while I start the car but no voltage since on coil and injector plug. It throwing 1124 fault code only.
Please what might be the cause (E90 330I 2006)?

I have solved the above problem. But now the car still won't start and give p0335 error code. I have changed 4 crankshaft sensor and still it won't start. I even have got 2 crankshaft sensor from a working vehicle and still it won't start and still throw error code p0335.
What can I do now?

Thanks for the update. Unfortunately, we need to get a new post started and work through this issue. We need to keep each post to one topic so that others can find the issues if they have a similar one.

Glad you worked out the other issue. Here is a link to start a new post. Thanks
