Working on a 93 toyota t100 with a v6 3.0 liter. It wont spark replaced cap, rotor, plugs, wires, coil, and igniter still wont spark. What do u suggest??

 

EFI/ECU/Engine Fuse?

 

Also tested those

 

Timing belt slip? Loose ground(s)? Battery charge ok? Circuit Opening Relay (COR) failed? Any work done prior to problem starting?

If you haven't already, take a look at the FSM that most closely matches your rig from the ling in my sig line. The diagnostic section....

 

Grounds are good, i will check the rest now

 

Alright tried all that above still nothin

 

Test wiring at the ECM. See page 3 of this pdf:
