on an 87 base. Just installed a used engine. I pulled the old one out myself, keeping the harnesses on the engines. Now we get no spark. Checked CAS and coils. Replaced ECU and trailing coil. Checked all fuses in and out. Anybody else had experience here? Any ideas? I have the fsm but its basically useless since it says nothing about troubleshooting the ignition system, only individual components.

TIA, please respond to hypntyz@hotmail.com
