Was - Did I kill my starter, ...? - Now - Please help me with my timing belt...
Hi after I redid my coolant reroute and changed fluids I stated my car today. Started well, then stumbled and won't start again. The loose sensor wire of my oil temp gauge might have hit my starter.
Now the car sounds a bit strange - like a wirring sound and doesn't start. Did I kill my starter or maybe? After a while of cranking some white smoke came out of the intake... And I can smell fuel... Maybe I give the starter a small push with the car in gear or hit the starter with a hammer... I will also try to reload my firmware on the MS3 tonight and reload my MSQ. I think I might have corrupted the firmware... Any other ideas? |
Shouldn't of killed it. I grounded my socket wrench directly to the power bolt a number of times, that's always the point in engine removal that I remember to disconnect the battery.
Mine's been fine, 120,000 miles and still starting strong. |
If the car is cranking then your starter is fine. I would look elsewhere.
|
I am a bit lost now here...
As I wrote above - The car started at the first try, ran for some second and now nothing. I cannot get reasonable RPM readings in TS, This is how the car sounds, when I try to start: I suspect something I can't really believe - could the cam belt be gone? I couldn't see a thing because of the covers and the darkness... Please help me out. I will try to reflash the firmware tomorrow anyway... And I will swap my DIYPNP and see if it starts... |
I fucked up your tube link, but it didn't work to begin with anyways. ----.
|
Should be working now...
|
Looks like no cam signal? What does the composite logger report?
|
Gonna look tomorrow... After the reflash.
|
If the engine is turning over really fast, it means no compression. I stongly suspect you've broken your timing belt. Pull your valve cover. It will tell the tale.
Fortunately, the Miata engine is non-interference, so this is actually not a big deal. |
No compression, no valvetrain friction. No cam-drive!
BTW, that 'white smoke' is fuel. No smoking... |
I am a non-smoker - so don't be afraid... ;)
I also suspect the cam-belt - the engine sounds so strange and turns over very easily... I am going to pull the Cam-cover this afternoon. Are there any good pictured How-to's about the cam-belt change online? I got the factory handbook but maybe there is something more pictorial out there... |
You might as well tak a peek through the oil cap.

I swapped in my DIYPNP and it's also not doing anything else... Might have to swap another cam sensor in... |

Here is a (very) short composite log:
https://www.miataturbo.net/attachmen...1&d=1332499357 Maybe someone could have a look... |
Not enough data in there, you need to crank more. However, the crank sensor signal does appear a bit odd.
|
I pulled the cam cover to have a look at the CAM belt - looks fine - though it seems to have some slack.

Will do as soon as the timing verified... I pulled a COP before I pulled the cam cover - there is no spark. The MS3 is working - verified on the bench/stim. |

@Reverant - nd the others off course too - here is a little longer composite log...
https://www.miataturbo.net/attachmen...1&d=1332513957 Please have a look Here is a pic of my composite log: https://www.miataturbo.net/attachmen...1&d=1332514800 And here a pic how the NB signals are ought to look: http://img38.imagefra.me/img/img38/7...wm_5981b1a.gif Looks like my Cam and Crank signal are out of sync??? The two following Cam signals should be inbetween two crank signals - looks like its a bit early just before the Crank signal - I am no expert on that, so please excuse my bad description... BTW - what does the red line mean? |
If both cam gears look properly aligned, then it looks like the crank pulley has jumped instead. All 4 teeth on the crank pulley should be fully contained between the 1 and 2 teeth on the cam gear. On your log, one of the crank teeth is between the two teeth of the cam gear.
|
I just edited my post when you replied...
This means a complete belt job I suppose...?! |
I guess so.
|
Could someone explain the red line in the composite log please.
|
Errors. It usually pops up on the tooth AFTER the actual problem.
|
New pictures - exhaust cam slipped one tooth ?!

Here are some pics after I removed all the stuff:
https://www.miataturbo.net/attachmen...ine=1332594802 Looks like my exhaust cam splipped one tooth - correct? Here are some pics after I removed all the stuff: https://www.miataturbo.net/attachmen...ine=1332594802 But what bothers me is - why is my crank pin not at 12' o clock and why did someone (my previous shop that did put in my built engine) make a mark at that point (which aligns with the cam marks (at least with the intake cam at the moment... :loser:) See pic: Here are some pics after I removed all the stuff: https://www.miataturbo.net/attachmen...ine=1332595893 Edit: More weirdness... When I align my crank with the pin up like this https://www.miataturbo.net/attachmen...ine=1332595893 I am at TDC for cylinder one... (I checked with a very scientific method...) http://www.ingenieure-reichel.de/upl...2/mx25_008.jpg With the Crank aligned like this the cams are standing this way: http://www.ingenieure-reichel.de/upl...2/mx25_009.jpg What the f...? Was my check correct, do I have a brainbug, what is going on...? Please help me out here... |
Nobody?
|
Looks like the intake cam gear is off 1 tooth, which is what you are seeing on the composite log. I can't even tell what is wrong with the exhaust cam.
|
Your timing is totally hosed. Whoever put the belt on set the cams when the crank was at BDC not TDC it seems.
|
Pull the belt off, check to see that the pins are in the proper place in the cam gears, and redo the whole thing.

I am going to do the whole timing again after I have seen that somewhat geeky but quiet helpful videos... |
I turned my crank today some more times to see if I can find a spot where the marks all agree... but they where really totally off. As to bee seen in the first picture above it looks like the 1st cylinder was at ~BDC when the cams were at the marks.
How could an engine run this way for 2 years...? Most of all - my signals must have been so that the DIYPNP and the MS3 were able to ignite and inject? Would this even be possible? |
It won't have run in that configuration, the belt has just jumped that's all.
|
Sooo much... :eek: o.k. then - lets get on.
Assembly as soon as I got my water neck blocking plate and timing belt / tensioners. |
Parts are rolling in..

Got the belts and tensioners today...
https://www.miataturbo.net/attachmen...ine=1332931780 The freeze plug is installed: https://www.miataturbo.net/attachmen...ine=1332931780 |
A lot of members, me included, put a plate over the freeze-out plug as insurance that it stays in position. A small weeping leak can be detected and overcome, a sudden empty system is another thing.
|
I should be getting that plate this afternoon - thank god I got a friend that can machine these things for me...

So I finally found the main problem that caused all that fuss... me...:vash:
Maybe I shoudl be renamed into Faezaphod or something like that... When I tried to remove my front waterneck this winter I removed the upper cambelt cover in a very Fae-like way... (though I didn't use a sawzall, but a huge screwdriver..) I removed the cover, did see that there is much more to the waterneck removal - and reattached the cover. But a piece of the cover broke and got ripped of by the cambelt and mangled between cambelt and the crank cambelt pulley... - I suppose that was the point where my cambelt jumped over quite a large bit... So on to the fix: That is my third hand I used when setting the cams and attaching the cambelt.. https://www.miataturbo.net/attachmen...ine=1333003686 Thats how it looks now - have to reassemble the rest today. https://www.miataturbo.net/attachmen...ine=1333003686 https://www.miataturbo.net/attachmen...ine=1333003686 Greets |
Just wanted to let you know that the car is up and running again.
At first I overtightend the belt - but the second attempt was good. P.S.: I had the timing light to reference the timing and I have seen that there is no difference between the DIYPNP and the MS3 in timing for the 99-00. |
