Exclamation Just replaced HG and now it won't start

Ok so I just replaced my HG and now I'm not getting spark. It's really getting frustrating. I made sure that it was at TDC before installing the CPS. I'm getting 12V at the coils and to the igniter. I checked the ground for the coils and it is good. I'm not sure what else to do. Once I get it running then I can adjust the timing.

Also once this is done I've got to do it again for my other Supra.

dont hijack this thread, fallow the forum rules and search the for sale section or post a thread for items wanted.

codes? what is your harness, a manual or auto? what sounds/does it do when you try and start it? need more info man to help you.

OK, I pulled the timing belt cover and the CPS and then double checked their alignment with TDC, Put it all back together and it started right up.

Of course now I have a really bad knock. Checked my valve clearances and 18 out of 24 are off anywhere from .001 to .003. I'm ordering new shims and then I will see if that took care of the knock.
