55 belair ls1 will not start need help I have a 55 belair that I installed a 05 4.8 in I also have hp tuners and I went into security and set the vats to none. I also even changed the pnrdl to none just in case I hooked it up wrong. I also did check and have power at coils at crank and run. I am not sure what I have missed. I also checked and have good fuel pressure. I am thinking I don't have something changed in the computer to have the ecm send signal to the coils to spark.

Make sure everything is plugged in, crank sensor behind starter is easy to miss. Also double check all your grounds. Pull the plugs and see if they're wet, if not you may not be getting fuel due to stuck injectors. Did you soak them? With the fuels today, the tend to gum up very quickly on an engine that's been sitting for a while.
VATS is really the only thing in the tune that will keep it from starting, if the tune is stock, messing with the tune if you don't know what you're doing will also, but it doesn't sound like you did. But even with VATS on, it should still start but then die right away. Does it start or try to at all?

Okay I pulled a plug and it was dry i checked and they are sparking. So I shot it with starting fluid and it started and died so injectors got clogged from sitting how do I clean them.

Lay in in a container with the pins sticking out of the fluid just don't submerge the electrical plug. It might effect the potting material inside the electrical connector which would be bad.

Okay well injectors have soaked for about 14 hours I went out and pulled one injector from can and tested with 9 volt clicked good and sea foam misted out the bottom. Go to the next and the other ones and nothing no click or anything so they are all stuck how do I free them up wvwn checked the first one again and is fine. So I have 7 stuck injectors. I have tried to lightly tap them not sure were I am trying to tap. I have them standing up right know with sea foam sitting in the top of them.

There are several interesting videos on you tube where guys clean injectors using different methods. Here is one that is pretty easy to replicate and pretty detailed.

Well I built a similiar setup and used the compressor at 20 psi and it only works on one injector the other 7 are not clicking to make the solvent even travel thru. They are stuck closed I have tried to gently tap around with screwdriver and can not get them to open.
Well I called couple local places and 800.00 for 8 injectors they are crazy I will have to order from ebay or get these to unstick so I can start it then send them out to be cleaned while I finsh it.

Try tapping harder!! lol
But you might have to send them out to get cleaned or find some local injectors. Most items you can get a complete truck intake with injectors for $100 or so.
