engine fires only briefly the

[drherr]

Need help, I’ve searched but haven’t found a similar issue.
engine will fire briefly then stop.
3rd gen 3sgte with ms3/ms3x COP running full sequential ignition and fuel. 36-1 wheel on crank,
RacerX cam sensor both with hall sensors.
1zzfe coils, Denso 800cc injectors, crower 2nd stage cams
All initial testing was good , composite log, trigger log,
injectors and coils all fired in the correct order, timing was set and stable,
no vacuum leaks, fuel pressure set to 44 psi.
Things I have tried
Running semi sequential
Altering AFE
Altering cranking pulse
Altering WUE
Nothing made any difference; any help will be greatly appreciated.
Attached is my msq file

What about changing ignition setting to wasted cop?

[billr]

Give us a run log (MSL), too.

Here's the MSL file

have you try setting you ignition to 'wasted cop'

[drherr]

I haven't tried wasted cop yet.

I haven't tried wasted cop yet.

Please do!

I'll try wasted cop when can (currently working 12 hour days 6 days a week). Would this indicate my cam
signal is 180 deg. out?

[grom_e30]

yeah pretty much, if it runs on wasted cop, turn back to cop but add 360 on to your tooth#1 angle and you should be good

[drherr]

Thank you all for the help, I rotated the cam wheel 180 deg and it started.
I guess I was a bit surprised the motor lit off at all with the timing out 180 deg.

now all I need to do is sustain a acceptable idle with the larger injectors, I knew
going into this it might be a challenge.

Thanks again!

the ecu will run in wasted cop and semi sequential during cranking until it gets the cam signal then it changes to fully sequential. so it was putting the spark timing 180 out as soon as it was getting the cam signal hence the cutting out. but the good thing is if you have a missing tooth main wheel and your cam signal fails the car will start and run
