Engine Cranks, BUT WON'T START, NO FUEL PUMP POWER, NO SPARK!!!!!
Ok so here is how it went down.
I was having my car idle while adjusting my new 102mm throttle boby when 5mins later the car just shut off. Went to turn it over and the engine just cranks but won't start. Now my fuel pump does not get power feed to it and i get no spark to my spark plugs. And it seems like there is no power going to the circuit box with the relays and fuses under the hood when the key is on the on position.
Here is what I have done so far.
-Checked all grounds and all checked out good.
-Checked all fuses and all good.
-Jumped fuel pump relay and fuel pump with jumper wire comes on when jumped, with relay just in will not with key in "On position"
-Checked relays with known good relays
-Replaced Crank sensor
-Replaced Fuel pump
-Replaced PCM
-Deleted VATS on PCM
-Injectors have power
I'm just so stuck right now, if anyone has gone through this or now of something to check please let me know. The car has been like this for over 2 weeks and i'm pulling my hair out.
Is there like a ground to the pcm that i'm not seeing or something????????

My buddy is having this problem right now, crank sensor is what we are trying next but you already did that. Maybe check to see if the pink wire that goes to the injectors has power. Are the injectors working at all?
