Bulb is good. Ground W on ECU to body (test in manual) and the CEL comes on. Says to check E1 to body ground. E1 wire is in a harness with 100 others taped and covered in plastic sleeve. Guess I need to find where it is grounded to the body. Book says it's in the air intake compartment. Looked...

How do I check if the correct voltage is at the ECU?

+12VDC at the fuse box.

If the fusible link provides the correct power to the fuse box I'm not sure of any benefit of changing it. On the EFI relay, fuel pump turns on, have fuel with pressure at the cold start injector and +12VDC at the B+ connector (test from the system test provided in earlier post) so those seem...

No real logic. Fusible links checked out fine.

I basically followed the Toyota manual that mentioned three potential issues with spark as coil, igniter and distributor. Considering all were 26 years old seemed a good idea to start there. Didn't work. So I started tracking electrical and checked fusible links. Good there. Follow...

So I have followed all the different suggestions posted above. Recap = coil, igniter, distributor all good. +12VDC at B+ on connector (understand this means EFI good). Even bought new ECU from Toyota. Just plugged in. Still no CEL and no spark. Flow chart on this post seems to say if all...

So looks like there are two fusible links. On white wire and one black w/blue stripe. Both have 12.5V at the battery and at the fuse box. So are they good I guess?

Got it. Thanks again for all the info.

Appreciate the info. Which fuses/relays should I check for the ECU? Have the original electrical diagram/manual but not near smart enough to follow that.

'91. No check engine light at all.

No spark after replacing coil, igniter and distributor. Have power at the positive on the coil. Cranks hard. Have fuel at the cold start injector. Fuel pump good. Crazy frustrated at this point. Any advice? Thanks.
