Ugh. I thought I posted this already:

What does the composite log during cranking look like?

and what's the VVT angle during cranking on a normal datalog?

When it starts on the stock parts you will first be relieved.

Check fuel, pump is running, fuel is pressurized at the injectors, either a voltmeter (or injector tester/node light of some sort) and use the test menu of the megasquirt to see if all injectors are firing and the right order. Then do the same with a spare coil and spark plug for the ignition. Probably 9 out of 10 you will either find an issue (who knows a cold solder somewhere).

Have had to utilize this after bashing my head at something hard in multiple occasions on a non-running car.
Fuel pump works for sure
Pressure is fine
Haven't checked spark but I'll do that.
No soldering pretty much anywhere besides the MS and its appropriate adapter harness, neither of which I touched since it last started/ran.

But thanks I'll definitely test spark

composite log looks okay. I'll get another one and post it up.
VVT shows 247* no matter what

Moar troubleshooting and datalogging incoming asap

VVT shows 247* even if you change the cam trigger angle angle?

There is only one angle/offset adjustment in megasquirt. Pretty sure its the crank one.

HAve you tried reflashing and reflashing your tune?

Worth a bash. Corrupted firmware is really rare, but does happen...

To answer the plug question, yes if they're really bad it can give you symptoms like you're experiencing (well, some of them.). Especially if they're still wet from fuel.

I don't think that's you're current problem, but we had a situation with one of the race cars where, even after we found what was causing the thing to not run/run too rich, it still showed similar symptoms just because at that point the plugs were really fouled out from all the cranking and barely running like crap episodes.

Once you get the rest of this sorted out, just make sure to check the plugs again.

I'm wondering if, with this engine installation, some part of the wiring harness didn't wind up on the exhaust or something else hot, and short out. That would possibly explain why it ran okay for a bit, before not responding at all. It was burning through some wires.

Are you going to put the stock inj and ECU in? If so, what about the E85 in the tank?

Another vote for stock ECU and injectors and running. Sorry to hear it man, hope you get it sorted soon.

And to answer my own question, apparently someone was able to do it:



Yes, I was like WTF for a few minutes as well.

did someone disable vvt to run an "adjustable" cam gear?

That's odd? They have the intake and exhaust cam gears reversed as well? WTF?

Took a break from it yesterday and worked on some subaru's.

Today I go back and start diagnosing again.

This was a '99 "euro" 1.6. They swapped in a 1.8 w/VVT.

They tried to make it run with an EFI Euro2 ECU, but they couldn't control the VVT, so guess what happened.

I will totally understand if someone flies to Denver and punches me in the face for this but...

Disconnect battery entirely, check grounds, reconnect? Totally cut the juice to the ecu.

Due to the stupid VVT1 error, I think we have a lot of focus on valve timing.

Edit: With it flooded this much, I can absolutely see you hearing some combustion in the intake side even with valve timing being OK. You have flaming crap all over the combustion chamber most likely and that flaming crap could burn for a long time longer than normal and light up a gas soaked runner or valve on intake opening once in while easily.

Roommate (who is a mechanic) recently figured out that an issue that according to OBD codes was related to the trans was loose grounds from the damned block. Cleaned 'em up fixed it, and bingo it fine. Oddest symptoms you can imagine, such as running OK for a minute, then staying in 2nd. The grounds looked right on the block, but they were loose.

VVT faults show up if the decoded angle is outside of the min/max allowed angles.

Did the trigger ring on the intake cam slip? Mechanical timing off (intake cam vs crank)?

Ben, can you shed some light on the 274 degree value? What that in relation to, or is it another way of saying it's flawed.

The trigger ring look to be OK in the pictures, similar to mine and you should be able to see an error with your eyes.

I'm not sure what you're referencing, and I did not see any pics. Suppose I can't read through a 51 page thread and then a 7 page thread to "come to speed".

Info on entering VVT settings to find the min and max angles is here:
Megasquirt-3 MS3 Variable valve timing (VVT / VANOS)
It's near the bottom of the page.

I have an MS3 set up and controlling VVT on my 01, but I don't recall those values off hand. However they were easy to find using the method in the link shown above. I don't have access to the car and/or its tune at the moment. You can send an email to [email protected] though, and I can look at it on Monday.

I was thinking of the fixed 274 value in Vlads log on page 1 or 2 of this thread (using VVTuner myself bit have a MS3 that will go in when I feel like some relearning).

Ok I'm back to working on it today.

Slowly removed the other car's vvt stuff, and right now slowly and very carefully putting everything back together.

By the way, we threw on the vvt stuff from my car onto the donor car, and it fired right up. So that part is confirmed not the problem.

In fact, now the only thing I have left to suspect is the ID1000's and Megasquirt.

Got 2 gal of 91 and going to swap ecu/injectors and try to fire it up that way.

Here are my timing marks, just to confirm for the billionth time:




car is confirmed at TDC
everything lined up
19 teeth between cam gears
vvt cam locked in place
