No spark to coil on '93 kick surprise

I found one in Kansas City that was nearly rust free, barely over 120,000 miles but sat for several years and I bought it sight unseen. It was delivered and I was told that it needed a coil and that was it and I'm sure you guys can guess the rest of the story. Someone had tried to trace a short or something, maybe mouse eaten, I'm not sure. Many of the wires were all pulled out which made it easy to start searching. I'd already bought a coil, put that on, still no spark at the coil. Cranks over strong, no fuel pressure. Found a blown 15A fuse under the FI slot  under the dash fuse block, replaced it and still not sure if the fuel pump is working or not, but I still don't have spark at the coil. Anyone have a suggestion as to what I could check next? I pulled the ECU and it has been redone in 2004 with smaller capacitors the board looked fine so I put it back together and still no spark at the coil. I checked my grounds somewhat, but I found this site and thank goodness it exists. I'm sure I'll be able to figure it out. I was just hoping for some guidance on the direction to take next. I also have way too many empty connectors as far as I am concerned, but I saw that it is common to have those. but I'll include some photos of those in a different post. I'm no electrical genius by any means, but I can pretty much trace wires, which is what I'm starting to do this morning.
1993 sidekick real.
in the USA there are 2 engines, 8v and 16valve,  the 16valve , valve cover says 16 valves what is yours?
is this a stick shift, or 3 or 4 speed automatic.? but it cranks so I don't need this fact.

newer caps are for sure  smaller, (technology advance)
the ECU tag tells what is there,  in 2 lines,   on any dead car EFI made this is first thing to see ,  and photo and share. if 10x better responses
is car 4 wd and 2 door?
is wiring eaten up by pack rats?  photos again are the best clue.

if the ECU sees spark bad in any possible ways  it cuts fuel dead, so forget fuel. until spark works. (saves tons of guessing no?)_

all grounds on dizzy base and fire wall and to engine direct all mater of EFI fails.

all cars made (99.9%) have empty connectors, for options never opted, that saves maker from having to make 100 harnessed to stock and make. huge savings there.
the spark suppressor is first. it is thumb sized under hood and if is missing all spark ends and tachometer goes dead (RPM)
cars like this have optional cruise controls.
and AC HVAC things,  does car have HVAC AC or just 1/2 of it missing, as many are now this old,
on 4door cars huge things possible missing (options)

here is  list, of 1st checks.  (there is no CKP sensor on this engine, crank sensor NONE until 1996) if you see one its a 1996 to 98 engine. and not connected here.
1: IGN spark suppressor not missing. ( tiny) 97view here   https://www.fixkick.com/IGN_timing/slide...sor97w.jpg
2: all fuses not blown, or missing, for sure IGN, FUel and DOME.
3: key   on CEL glows, it must glow then go out running but will not run so just glows telling us ECU is not really dead or fuse to it not blown and lamp is not burned out.
4: spark fails at coil right ?direct to coil not out put of top of distributor  , check at the coil directly using a test spark plug and hv wire connected coil to plug directly and shell l of spark plug grounded to the engine metal.

5: cranking engine, rotor turns if not cam belt snapped and now dizzy is dead and CMP dead and all spark Dead 100%
6: cam belt can slip and ECU sees it way way off and does not creat spark via the IGNITOR.

fuel is cut the second CMP goes dead. to stop crash and burn events.

CMP is the cam sensor in base of Dizzy.
7: ground bad. to ECU or distrib or ignitor .

8; no hacked up wires to ECU or Dizzy or ignitor allowed,. eyeball them.


the 8v ignitor is right next to spark coil

the 16v it is deep in side dizzy. (most are)

hey good luck and thanks for sharing !@!@!!!!!!
