Strange no start issue
Recently had some clamps on my turbo/wastegates/downpipe replaced. I drove the car around, ran great, decided I wanted to do my oil change. Pulled up to my house, set the car up and did the oil change. I left the car for the night deciding I'd drive it in the morning.
Fast forward to the next day, go to start it and all it does is crank.
I have: Fuel, injectors are firing(plugs wet), no codes, timing is dead on and all fuses were checked and good.
I don't have: spark, 12v at the coil plugs,any voltage from signal while cranking, a signal in evo scan from the CAS.
Did a voltage test and I get 12v to the CAS and between .6v-5v on the signal wire while cranking the engine by hand. I ordered a CAS sensor as a precaution.
Also did continuity tests on all wires I assumed were associated with my issue and nothing is shorted or fused from what I can tell. My buddy swapped a cam position sensor out of his evo and it didn't change anything.
I do have an aftermarket alarm that was installed by the previous owner. Ungo sr7000. Although I've never had any issue with the system I don't want to count out that it could be part of the issue.
Dual Walbro setup,2150cc injectors,SD, Fully built 2.0
Any helpful suggestions are appreciated.

How did you check for the injectors to be firing? Did you use a noid on the injectors? If not then I would recommend getting a noid to test them with and check your CPS and grounds
