Do I need a new wire harness

[built420]

So have been working on a turbo build and car is still having a starting problem that only seems to get worse. I put a new ecu also check my cam and crank sensor both seen to be working good. But I go to start my car and it will crank but not start also my fuel pump will keep priming as I'm trying to start the car and my rpm gauge will move up and down for no reason and the last thing is my dash lights all flash at me. I find this very weird and never had this happen before when trying to start my car. Any help would be great thanks!

You need 3 thigns to start a car, fuel (which it sounds like you have), Compression (if its trying to turn over you should be good) and spark. Take a spark plug out and set it on the VC, crank it while having a buddy watch it to see if the spark plug arcs to the VC to confirm spark. Check your fuses, maybe you blew the engine link fuse?

The car does start but only like once a month and I usually have to crank it 5 or mor times. And it will run kinda crappy. I've checked asd relay and the sensors replaced ecu which helped when I put the new one in, it would start but now its back to being dumb. What else should I check?

Timing!

The timing is good the belt was changed and it wa off a little but my shop fixed that.
