B2200 issues no spark

92 b2200 efi reg cab shortbox.
No spark replaced icm new coil on its way up here to pothole city.

Computer looks good no corrosion.

I am not getting power to coil when key is to start but get it when turned to on position

Any ideas?

Have you checked the ignition switch (the electrical part)? These give up after about 20 years on these trucks. The contacts for power to run the truck in "run" are different than those in the "start" position.

I have the black with white striped wire on the ignition switch having power when key in on position but not start?

The white wire is the power feed to the switch.

In the on or run position: the BW (black/white), BY (black/yellow), and L (blue) should all have 12V+ power.

In the start position: the BY (black/yellow), BR (black/red) should all have 12V+ power.

Blue is accessories, BY is ignition1, BW is ignition2, BR is for starter.

Backstory on issue.

Went to get some grub, park truck shut it off, do my thing, came back back out didnt want to start.

Before incident truck ran smoothly. Fuel economy was decent.
I had just finished putting a new fueltank and sender in a coulple days before. Fuel sock was clean looking stillz

have you check the engine fuse theres one under the dashboard that says engine fuse and also i think theres like two more under the hood

Yes both fuses are good. New coil coming in tomorrow will give that a shot and see

I am getting fuel to injectors. I also ran a temporary wire from battery to positve side of coil. Still no sparky.

Tested distributor using multimeter. No flashing but two middle wires of plug are getting power.

New coil in and still nothing.

Doublechecked with wire to coil from battery still nada aswell.
