Swapped to supercharged

So I just recently swapped from N/A to supercharged, put everything back the same way it came out, checked, re-checked and checked again and I must be missing something because it will not start at all. It cranks, starter works, got fuel pressure, got oil pressure, changed ICM, good grounds, battery new, alternator good. I used the coil pack from the N/A engine. Both engine ran before the swap and I also did the necessary wiring for the boost control valve/maf sensor extension. There are also no codes showing up on the scanner either. It really sounds like there is no spark. I need some help please:th_laugh-lol3::th_laugh-lol3::th_shakinghead2::th_shakinghead2::th_shakinghead1::th_shakinghead1::mad::mad::mad:
 


try a security learn, key to run for 10 minutes, then off for less then 10 seconds, back to run for 10 minutes, do this 3 times, then try to fire it up.
 


The font is clear, you need it larger?
Oh yea, Scotty, do I still do the security re-learn even if the security light goes right out after I turn the key to the on position?

 
i would. when you change pcm's 99% of the time the os dont match and you need to pair up the key to the pcm. takes 30 minutes, but its likely the cause.
 
So I took the injectors off to do cleaning and guess what, yes they pulse after i tap the positive, but the spray,no spray, just a cpl drops and then nothing, just pulsing. I tried to clean them all and they all did the same thing. They're finished.....
 


When I accidentally reinstalled my 2 bar NA MAP sensor instead of the 3 bar SC sensor I got a no start condition. No codes, crank fine, but no fire. PCM turned off injectors. Swapped the MAP sensor to the 3 bar after I noticed it while troubleshooting and fired right up.... Food for thought....
 
I did this exact method and they didn't spray, it just shot out once while i tapped the positive, my daughter sprayed full tilt and all it did was fill the hose with cleaner after the one shot. I did them all with the same results, re-checked, same result, nothing, just pulsing. That means they are cooked right?
 


The video did say don't let it full spray because it would burn out the injector. It is designed to pulse rapidly.

If you have a volt meter check em out I'm not sure what they are supposed to read but depending how long you full sprayed them they are probably burnt.

At least they are affordable. Rock on rockauto

No, I didn't just touch the positive to let it shoot out once. I tapped it to make it pulse and I only got one shot of fuel from the injectors. I already know they burn out if you just hold it to the positive.
