Distributor no spark

I am working on the truck listed above. I have tested the distributor multiple times. I get power to the distributor but no spark out. I have also tested for resistance in the igniter and in the pick up coil. I also changed the condenser in it. I also checked the air gap for the cam sensor and the timing chain is fine too. What do I do?

You have to look at the wiring diagram and check the signal to the computer. Is the rpm signal return to the ECM that trigger the computer to generate a signal back for ignition? Cam sensor defines as signal of rpm input.

Thanks, I would have never thought about the rpm's my next step of course was the ECM since I have been through 3 distributors. Thanks again. I was wondering if maybe an anti theft device or maybe a fuel cutoff like some GM's have an anti theft device that will let the car start but will only run for like a second or two does Toyota have anything similar?

The ECM has to get the G and Ne signals if not it will not give the Igt signal to the igniter and also no igf from the igniter which is a confirmation of an ignition back to the ECM

Also check the injectors whether they clicking/buzzing while cranking.

3 Distributors-start check the wiring to the ECM.

Confirm that the EFI relay, EFI fuse and Ignition fuse are in good shape.
