HELP! No Spark No Fuel
hey guys, I'm having a big problem trying to get spark and fuel from my engine. Not sure what it could be. Trying to get some ideas going
ok so i tried doing a wire tuck and finished it. Not the greatest, but not the worst. I depinned and repinned all the plugs and wire back into place. (I took pictures of each one making sure i put them back in the right place) I grounded everything that was on the engine bay harness and on the chassis harness too. I just finished rebuilding my engine I set the timing with the CAS, but it says to align the notch with the orange dot. But I didn't have a orange dot, but I did it to the dot that looked like the one on heavythrottle website.
I double checked the my wiring with someone else on Nico who did a tuck and mine are pined back exactly like his.
I have already checked for power to the injectors and coils with my multimeter nothing. The fuel pump primes because you can hear it and my FPR gauge shows it going to 43 psi and drops down to 23 psi after it stops priming. I know the CAS works because when I have the car turned o the "on" position with the key and I plug the CAS plug in, you hear the fuel pump priming. I took the plug out of the MAF to throw it into limp mode, but still nothing.
I took the ECU apart checking for burn marks, seeing if the ECU might have burnt out, but nothing was burnt. I turned the car to "on" position and I check the ECU for power and there is power. I tried another friends ECU, though it's a tuned ECU, but should still be able to get the car to start, and the same thing happened. No spark no fuel.
So only thing I can think of is a bad ground, maybe a relay or fuse.
just trying to get some ideas going to see what else to test for.
no i don't have a oscilloscope and I double checked my grounds on the ECU. Everything is grounded.
But i was trying to test the voltage of the CAS and I got numbers that were way weaker than what they're suppose to be. Think I remember reading somewhere it's suppose to be reading 2-3V when cranking, but I was only reading 0.15-0.2V when it was cranking. Can anyone telling if this is correct?

ok, I didn't check the CAS correctly, but I will try again tomorrow if weather is good. but it looks like it's not my CAS either =/
Any other thought guys? i might just rip my whole engine bay harness apart and redo everything. =/

this is where i'm getting my CAS information incase anyone having the same problem as me.
oh and also forgot to add. I checked the igniter chip. there was no signal from the ecu going to the igniter chip. i tried all 4 wires and nothing on anyone. so this is what lead me to a bad CAS or a bad ground. going to check for a ECCS relay over by the driver door tomorrow and check for voltage in the ground int he ECU.

thanks in advance.
