Video of car trying to start

I have a 2011 evo x, it cranks but does not start. Back story I fried my ecu trying to flash and the cobb got stuck in the middle of the tune and killed my ecu, so I bought a new ecu got it bench flashed with my tune put on it, got my vin coded on it with a mut3 tool. my mods are turbo back exhaust, 1000cc injectors, intake, UICP electronic boost controller, and walbaro 450 I've made sure its getting fuel, getting spark, I don't think it's my immobilizer because it should even crank right? It ran fine before the fried ecu. I even out a stock 2011 tune on it and then back to my customized tune so the ecu is good, I don't have any codes. The car ran fine before this happened. This is technically my 3rd ecu because the 2nd got bench flashed by someone and it started smoking and fried that one lol. I'm at my witts end, there are no good shops near me so before I truck it across the state anyone got any advice? Could it be ecu related somehow even though the ecu looks to work fine?

The tune your car is using does account for the injectors right?

Yes it does.

How have you confirmed it's getting fuel and spark? Are the plugs wet after you try starting? Are you getting any pending DTCs on the ECU?

It is getting fuel and spark, I did not notice that the plugs were wet, I just double check and I actually am getting some codes now and they are U0100, C1617, U0401.

It could be you're getting fuel to the rail but the injectors aren't firing. Those codes are ECU communications codes.

Double check your ECU harness and make sure you don't have any bent pins. Could be a bad ECU or flash on it too. Do you have a Tactrix cable or just the Access Port? Do you still have your original ECU or is that the one that got burnt on the bench?

Going to check the ecu harness later today, I do have original ecu, cobb tried to restore it after it got bricked and told me it was fried. I do have a tactrix cable, and I have even been able to flash my custom tune on it and also a stock 2011 rom through the tactrix cable.

If it all checks out and it still won't start, you could try the ECUflash method to see if you can revive it. In ecuflash , go to options use alt flash mode. Try to reflash, and it will fail. Then go back in to normal flash mode try to reflash it. This works for some people. If it is dead, it's dead but you don't have too much to lose at this point.

Update; I am getting code p0335 replaced that crank sensor and still getting the code. I had a buddy double check my work and I'm not getting spark, maybe someone has an idea haha
