2000 3.0 not enough spark to the to the coiloack

Hey y'all so my 2000 ranger with a 3.0.im chasing my taill it has 2 refurbished heads and gaskets new wires,plugs,cam sequenizer, crank position,PCM refurbish and reset with forsCan new battery I have gone through the wiring harness still not getting fire yes I have the plug wires are right

So crank position sensor was changed? How sure are you that the new one works?

Also make sure cam synchronizer is set properly. Would be good to check ground connections from block to battery and there is usually one from the back of a head to the firewall.

I checked resistance and the PCM is not throwing a code

Yes I put all new ground wires on when I put the heads on

no spark or wrong spark?
did you put an old plug in a wire and verify it has spark?
have a timing light?

at the coil pack RD/LG is constant power in start & run.
the PCM grounds the other wires (one at a time) to fire the coil.
when the coils are not firing the 3 wires will show full voltage because there is no drop across the coils.

those grounding pulses are very short and meters have a hard time detecting them so it appears to be power on all wires all the time.
