Default 93 Sami. No spark No fuel. Rebuilt ECU

Just got my ECU in yesterday thinking it had to be the problem. Popped it in and nothing changes. Relays click, motor turns over strong but not getting any fuel or spark.

Before that I inspected swapped out-
*coilpack
*Ignitor
* timing
*inspected. distributer and wires

I have power to the coil. I've bench tested the fuel pump. I've come to understand that the fuel pump won't kick on if there is no spark I'm guessing this is why I have no fuel. I'm suspecting maybe some signal wire from the distributor to the computer. But still I'm at a loss. WHY NO SPARK?!?

Please, any help would be muchly appricated.

I'd estimate 99% of all EFI vehicles and probably 100% of Suzuki EFI vehicles will run the fuel pump whilst cranking the engine.

Suzukis power the pump on for three seconds when the ignition is switched on and then shut it down until the key is turned to the start position, once the engine starts the pump will continue to run until the engine is either switched off, or it stops running for any reason.

Some vehicles are fitted with an "inertia" switch that cuts power to the pump in case of an accident, but I've never seen Suzuki do this.

Not having spark will shutdown the fuel injection (to prevent flooding), but not the fuel pump.

Does your check engine light work - it should turn on when the ignition is switched on and go out after the engine starts, although, if you can't get the engine started, you won't know if it does go out, jumper the diagnostic pins and see what the ECU reports, at a minimum you should see a "code 12" reported, if you get that, leave the jumper in place and crank the engine, does the code change?

Does this one have a distributor?
Does the signal go to the ECU?
Does the ECU signal go to the Coil?

Is the ECU getting power?
Main relay?

Just wondering
