lt1 swap no start
I did my 96 lt1 swap in my 94 formula.
I finished everything up went to start it just cranks n cranks. I checked the fuel pressure its got pressure up top. So i checked for spark i got Nothing dam im pissed at this point...
Checked no 1 plug no spark.. checked the coil nothing.. what can be wrong? I dont have a ground on the battery to body can that be n issusr? How do i start to fix this issuse? Let me kno thankx

I will check everything over again tomorrow.
Secondly is the ground needed for the battery to body? my harness didnt have a second ground from the harness only connects to the battery.
Third how do i check to see if the icm n coil get signal from the pcm? Do i disconnect the opti side of the plug wire n put a spark plug there to see if i get spark from the coil?

follow this step by step, also check the terminals on both sides of the opti connector, they are known to get corroded.
Did you replace the opti? if you did, are you sure you installed it properly? If you have a cam-dowel driven opti it can easily be installed incorrectly.
Im going through the same thing with my swap so ive done all of this multiple times, lol
