Torqhead install not starting
Ground problem.
Fuse
The TH system uses genuine Crank & Cam sensors. Very rare. But need to rule them out.
You have a stand alone ECU.. Holley EFI Mgt?
Did you tap into your harness?
No longer on the factory ECU/ PROM combo. Correct.
Sorry, to hear that.
I'm sure it's simple. Oversight
At this point. The TH kit is plug & play.
Mine fired up instantly.. super smooth. My only issue was the base tune, ZF pulse, Fans not kicking in.
But. I purchased at the threshold of proto/ release date. I know that kit should be perfected. Now.
Paul is great to work with. Shipping to CAN. Is not fun. Did that once.
Quickest. Resolution. To eliminate online ship time.
Local store. That has a OBD II scanner. Due to the fact you converted to OBD II. Simple is ok. More advanced is best. Like datalog.
You will need to datalog everyday. Start, idle, part - WOT. Especially when you connect. Boost.
If i were you. Get a wideband. Install. Pre turbo.
The wide band is invaluable.

Paul, did flash your VIN onto the TH~ PCM. correct.
Future. Someone will need to tune.
You have some homework to do.

Two kits. Pro kit with a adapter to montior a Wideband while datalogging. Fantastic feature.
Standard kit. Cannot convert. However. They allow a trade- up credit.
Your choice.
Software is licensed per PCM = pay for other PCMs.
But you currently only need to tune one PCM.
Cost effective.
or way more money for a series of models. Price is per credit.
1 credit = $49.95.
The ALDL cable you can find places like CATS, tunerpro.
Two styles to choose OBD I solo cable
Or a Y cable to use on both OBD I & II
I have the Y cable from CATS. Industrial quality very thick. This current cable price. is double. Compared when i purchased. Mine.
I know mine works with. Datamaster and of course HP tuner.
Hopefully this helps out a bit.

The downside. Calculations like Diag codes from dash, the driver information system/ Trip monitor Avg MPG & related. Non existent. Due to CCC connection.
Unless a recent revision was made?
This sucks. After tuning the factory PCM.
Nobody will/ would believe my average MPG
Just enough contact to feel drag/ Resistance.
Re-read from TH my previous is backwards
Straight from TH
***Crank sensor spark critical***
"The crankshaft reluctor has 24 unique pulses per 360 degrees of engine rotation that the Gen 3 PCM interprets to know engine position. This is where the "24x" terminology/saying comes from.
**** Cam sensor spark on / off****
The camshaft reluctor provides what is called the "1x" signal because it is either on or off for 360 degrees of engine rotation. The camshaft reluctor allows the PCM to know an important piece of information.....whether a given cylinder is on its firing stroke or intake stroke"
End result. Your coils are connected, good fuse? proper crank sensor gap. NO spark.
Unknown reason points to the crank sensor.
What did Paul say. Besides the crank sensor gap looks good.
