if you had a volt meter , you could easily dispell the bad battery idea.
WONT start but runs on test gas ( so spark is ok so is compression)


Here are the ECU tests , yours is probably bad , but you need NOID.
ECU

wont start
nostart


here is the noid test.

I have fond the solution
And it only cost me 1,5 euro's

When i looked up this site.
link : ECU

this link rely helped.
I went to the local electronics store and bought 3 caps for 1,50 en replaced the leaky once in the ecu.
Then i try ed the ecu again and still it did not work. So i looked on this internet again and found this link :
Bad computer? SO your EFI is acting up...

He describes that the caps leak corrosive stuff that eats through print lanes.
So i checked the surrounding print lanes and yes there was one that measured 40 ohms (it should only measure 1ohm or less) so 40 was bad.

i created all new lane by connecting a wire from the cap to the nears component.
then i measured again and it was 1,5 ohms so it was oke.

put the ecu back in to the car.
and no more clickingen it started with the first turn of the key

so 1,50 and about a 30 minutes of measuring and repairing fixed my car.

So i want to realy thank jtgh for replying.

 

you are a very good tech, dogmatic , "gets er, done!"

the caps on all these cars 90 to 94 , ALL LEAK, ( or will soon)
it is a known problem ( poor quality caps used)

YOu win the Skin Flint award for 1.5 Euros !!!

Others:
there must be NO contamintion on the board or leaks
there must be no damaged PCB traces. they most all be 0 Ohms perfect
conductivity.
There must be no cracked traces or cracked PAD EYE to Components.
these are called plated thru Holes. "VIA'S" to a tech.

Some times the board can be fixed by RE-soldlering all the holes.
all the large ones, then retest. ( IC's hold up well skip them)

the large ones are under a lot of vibrational stress and can fail.

the # ECu link i mine. It is evolving as you guys find new ideas.
Wish I had transistor #, need them. I have source if we can get numbers and would document it. EG: lick: C123 ( = 2SC123)

for others : this was a TBI Sidekick 1.6L and would have failed ,
my radio-shack , NOID lamp test. see link.

EG: no injector signal.

I am not sure what NOID means?, "No Output Injector Driver" lamp.
WWW googles fail to find meaning, I submited to wiki a demand for
stating what it means and showed them all the NOID kits for sale to prove my point. We will see.
