Spout Out = Spark, Spout In = No Spark

[thumperf350]

Help before I throw this and myself off of a cliff!!!

Application:
Ford 347, TFI, MS2, Adapter Board, LC-1 Wideband

Problems:
Car won't start with spout in
Car starts with spout out but very rough and rich
No Spark with spout in
Wideband won't read in Megatune (brown wire from LC-1 connected to pin #29 on adapter board, Single Wideband Sensor in EGO Settings, LC-1in AFR Settings)

Information:
Followed all of the ignition steps in the Megasquirt your Mustang on DIY
Was able to get the trigger wizard going with the spout out

I have read at least 3 posts where somebody has the exact same symptoms with no conclusions which further drives me crazy. there was one guy that forgot to jumper JS10 to IGBTIN and had the same issues but I have those jumpered. My other MS board jumpers are S12C to JS9, JS0 to IAC1A, IGN to IGBTOUT, TACHSELECT to OPTOIN, R39 jumpered, D1 Jumpered, D2 Resistor

I don't have a diode across accross the PWM valve. I also do not have a resistor from IGN/IGBTOUT to S12. I don't know if these are necessary or not for my application.

If you need anymore information I can get it to you asap. Thanks in advance for any help that you can give.

Also when I calibrate the Thermistal Table and AFR Table, when I return to the window the settings that I input are not there. They are set back to their default values.

Okay I've been nonstop reading on the forums. I've fixed the situation with the O2 sensor and it seems as though the car is running a bit better but it's still way too rich. It might just be placebo making me think that it's running better due to fixing one of the problems... The rest of the symptoms are still present. I will do some further trouble shooting in a few hours but if anybody has any ideas let me know. Thanks

First, I'd get the running rich issue fixed by adjusting the VE tables. This will at least make starting easier. Also, could you post a copy of your MSQ?

Matt,

I toned the fuel down a bit and had it in the 13.5 range. I enabled the autotune feature under tuning/vetable1/tools and a lot of the fuel came back. I'm going to knock the fuel down again tomorrow but even with the fuel down and the spout in i'm not getting any spark.

Thanks for all of the help thus far!!!

MSQ looks OK - what's in the Q16 slot on your board?

[thumperf350]

Matt,

A quick thought and correct me if I'm wrong. If I set the timing to 10 degrees with the spout out then that would mean that my initial timing is set and should fire with the spout in right???? Would this be the sign that the timing is set to stock and should fire??? I tried 10 through 18 degrees as well and no go.

[Matt Cramer]

I'm not sure I follow that question. Generally, your trigger angle should be very close to your initial timing. You may want to change the spark output inverted setting just to see what happens, though.

I with the help of my room temperature IQ realized that I didn't have a mica insulator between the rail and Q16. Installed the mica insulator and everything is good to go now. on to tuning

I've edited our Mustang document to add this. The number of "My TFI's not working... Oh, wait a minute, I fixed it!" posts with no explanation of what happened makes me think you're not the first to do this, but may be the first who's admitted it.
