I posted in there too but I could always use some more suggestions.


Cliff notes, lol:


got a new 530!

$hit.. but on the way home.. there was oil in coolant and coolant in the oil

why didn't the owner tell me :(

oh wait.. it's not that bad.. we'll make it a nice project :)

got the parts.. putting it together :D

$hit.. won't start :(

we'll figure it out.. probably something small




damnit.. still can't figure it out..


Running out of time .. getting colder...






Basically the car keeps turning over and not starting, obviously. I've checked everything under the sun. Theoretically, it should start if it has fuel, oxygen, spark, and compression. Fuel pressure is good, brand new OEM spark plugs, no vaccum leaks, getting air, coils were tested and give great spark, compression is 140-150 and holding in all cylinders.

Everything is connected, full coolant, new oil, all gaskets from the heads up are new. Only thing not connected is one side of the exhaust.

Please help!

Ok, I havent really been involved in this thread so Im not sure of what all has been reccomended...

-Fuel yousaid you have pressure but is it being injected into the cylinders? EWS or CODE in the OBC will still allow fuel pressure to be present but wont allow the injectors to pulse, thereby cutting fuel to the cylinders.

-Main Relay, Im sure you have checked this already, but depending on what pin on the relay goes bad, you can still have fuel pump but the DME will not be powered. A simple way to test for that is to see id the "check engine" light does a bulb check when you turn the key on.

-Crank and Cam signals, obviously you have to have both of these in order for the DME to determine fuel and spark timing.

-Fault codes, is the DME throwing any fault codes that may help simplify the process of diagnosis?

I hope maybe something here helps, good luck on the progress.

I'll go down your list of recomendations...


The fuel is definately getting into the combustion chamber. The spark plugs are wet when we take them out.

The main relay looked good but we replaced it anyway. The fuel pumps are working too.

The crank sensor is brand new, and the cam sensor check out okay.

When we checked for fault codes, the "check engine" light just keeps flashing forever. I believe that means that there are no codes, but I'm not sure. Is there some kind of code reader I should buy?

You've not managed to accidentally cross the spark plug leads over onto the wrong heads? (Just a thought - not sure if it's actually possible or not - just tossing crazy ideas in)

Good question - when rebuilding mine for the first time I got one of the cams out by just a tooth and it wouldnt run properly - would hardly start at all. Two teeth and I think it'd just sit there smiling at you refusing to start.

Antrieb

There is no way we crossed the ignition coils, never un-did the wiring there.

The first time we put the car back together, the timing was definatly off. We got the proper timing tools for that engine and re-did it and found that we were infact one tooth off. Now we should be exactly perfect. If all else fails, I will take it apart for the 4th time to once again check the timing.

Unless, is there any tool that I can buy to check if the timing is correct?

Should it not flash 1444 at you? Thought I read somewhere that you had to do something to set that code in there.

Off of BMWE34.net:
Clear the codes
1. Read the codes. At the end, make sure that the 1000 code (short blink and nothing) is present then depress the accelerator for at least 10 seconds.
2. To check, depress the accelerator pedal 5 times within 5 sec and make sure that the 1444 code (no fault stored) is present.

Have you tried that?

Antrieb

It did flash 1444 at one point, but now it just keeps flashing. We didn't depress for 10 seconds after we were done though.

You stated that the cam position sensor "checks out". On an M60, is there a meal tag on a cam to send the signal to the sensor? I had the same issue on my M50, when I "sigh".....installed the metal ring on the cam upside down.

Needless to say, it wouldn't start, I checked fuel, spark, air, scratched my head utill I found my F' up

Here's some of the things to check I can think of off the top of my head.

A. A compression test.

B. Check the static timing again; not only that the crank and camshaft pulleys are where they should be at tdc on #1, but the the camshaft is in the right place.

C. Get a multi-meter on the LT side of the coil. Ideally something that can read frequency, or failing that set to an AC scale and crank engine (make sure meter is over-volts protected). Ideally an oscilloscope.

D. Multi-meter on the injectors. Again ideally a scope with the LT of the coil on one channel and an injector on another so I could see the relationship between the coil and injectors (are they two banks of 3 on yours or individual?).

My stepfather talked to one of his friends and he had a suggestion for me regarding the timing.

Set the crank to TDC, lock in the flywheel, lock in the cams on both sides, take off the cam gears on both sides, take out the flywheel lock and turn the engine one revolution in the normal direction. He said this will reset the timing, but I don't see how it will do anything. Is it worth a try?

He is assuming you are 180 off. Keep in mind this is an "interference" motor and spinning the motor aroun with valves hanging open isn't a good idea. Stick with the proper procedure.

You've not accidentally turned a cam through 90 or 180 degrees have you - it's very easy to accidentally put the sprocket back on wrong?

Also : fuel injectors firing when the intake is closed is also the only thing that will cause a car to turn over and not fire/backfire. (Would explain wet plugs as well)

Otherwise I'd be expecting fireworks and bits of catalyser to come flying out of your exhaust

Hey Mr FERR....what would possibly cause cluster to no longer function as before or prev to engine being replaced? In short I bought my 525i from two farts who had no idea...they replaced the one of the heads, not sure , but my mechanic recognized that the timing was never synced after the head was replaced...They were then under the impressions(two farts) that the car would then never run right as it sounded(like nails pouring down some steps). My mechanic went to say "buy it!!"....for $300.....they sold it as is, my mechanic dropped a new engine ....she has been stroking since, except I may run out of gas. Before the engine was replaced this cluster worked fine now ... i can't figure it out. It also works on warm days and/or after she hit 60,000 or greater on rpm?? jpeg

That cam set is in time - or at least is in the right orientation - see the front two lobes? when their tips are pointed inwards and upwards like that, the cams are at tdc. I dont see the cam position sensor on that - is it on the other head?

EDIT: *quickly changes words before anyone notices* CAMS NOT CRANK *headdesk*

Well its pretty darn close to crank TCD. I crawled under the car to put the flywheel lock pin in there but couldn't find the flywheel hole. It's kind of hard to do it with one person.

The arrow on the camshaft gear is pointing 45 degrees away from the direction of the head in the up and out position.

Yeah, that heads pretty much in time, I'm just wondering about the crank position sensor and it's plate now... if the other head is a mirror image, then your timing will be close enough to at least to make the car splutter angrily and backfire rather than just not working at all.

The only thing left really to be suspect is the sensor itself and the timing plate to go with it.

i was away and thinking about this and it dawned on me...fuel wash? Fuel, spark whats missing? Compression. Fuel wash will unseal the rings from the cylinders and give you too low of compression to start it!

If everything seems dead on I would suggest a squirt or two of trans fluid down each cylinder, turn it over a couple times then re assemble the plugs and coils and see if she fires.

Sorry this completely slipped my mind.

OK, whos wit me on dis one? I had to answer my own question about the cam sensor thingy, so I went to Bentleys and discovered that on the M60 the 'sender' is integrated into the intake cam sprocket on the pass. side head.

As someone earlier said, it looks as though the cam lobes 'aren't quite right' and I agree. Look at bentley's arrow on the cam sprocket, then look at the photo. It appears there may be room to turn the intake cam and sprocket further inward. Maybe just my eyes, but.....might this change the ignition timing enough to get her going?

Does it not fire or stutter at all when cranking on the starter?

I'd have thought that if there was a head/cylender fault it'd still be trying to fire on at least four cylenders out of eight.

Hmm, this is crackers.

Edit : Even if one side is out of time, the other should still try and fire... so long as it's not the sensor side that's out of time.

Hmmm, do me a favour and while cranking the engine test some voltages for me?

While cranking:
Test the voltage output at the cigarette lighter socket.
Test the voltage between the engine block metal and the negative battery terminal.
Test the resistance across all temperature sensors.
Check every fuse in the fuse box, if it's got an alarm/immobiliser they tend to take power from very strange positions... like the interior lights.
You may have fuel flowing, but do you have the right pressure - I cant remember whether you've said about this before?

It appears to be the sensor side that is out, hence both the valve AND ignition timing are out. Interested to see what happens once the cam alignment is double checked with a good tool.

Whip out your injectors out of the manifolds if you can and crank the engine - they should be literally flooding the place with fuel. If they're not you've not got enough pressure to start - if it does rumble every now and again while cranking that sounds exactly like my 525 the first time I put it back together with a single tooth out.

When my cam sensor ID ring was buggered, it would 'feel' as though it was going to fire, but really, it had no chance.

If you're firing starter fluid into it, you're over-riding the fuel ijection timing and probably getting lucky withthe odd spark. Not sure if you can cause damage doing such a thing, I guess it depends on how far out your timing is and how tight the tolerance is on the M60.
