I have an 87 7m-ge in my 77 celica. I have eveything hooked up and I'm not getting any spark. The ecu has power. don't know where to look next.

Grounds hooked up? There are some ground leads on the 7m harness that bolt to the intake. Seems people like to put them on the starter. They should be brown, iirc, and have an eyelet on them. Think there's 3 wires on one eyelet.

This can get way beyond me as far as the wiring is concerned. About the only other info. I can offer is check the fuses, and make sure there is power and ground at the igniter and coil.

All my grounds are hooked up on the intake. the coil and ignitor are grounded. I have power at the ignitor.
I have all the wiring diagrams printed out.
