Fuel issue on 1983 1.8 GTi

Main issue I have on non- start is fuel at injectors or lack of it.
Having cranked it over a few times, there is fuel at all banjo bolts/joints when you loosen them, with the exception of three of the outlets to the injectors - these seem dry or barely weep rather than hiss out under pressure..
There's a healthy hiss from fuel cap when you loosen it so pressure has certainly built up.
I don't have a fuel pressure tester so don't know what the pressure is.
Just wondered if there was something "daft"
Thanks in advance.

Having rebuilt my Campaign, I'm gradually getting round to starting it.

I think it's a bleed/air in line problem as there was air hissing out of the return to tank banjo when I loosened it off. I've a full spare metering unit and fuel lines so could try that if all else fails.

I stuck a wire in the two big fuel pump relay connectors so the pump ran and lifted the meter head plate until petrol was coming out of the injectors.

The trouble with doing nothing is that you never know when you are finished.

I've done as suggested and lifted air plate and now have fuel coming out of injectors. Would this mean with the air plate down it would still provide fuel to the injectors? I haven't put the rubber boot yet so would need to reassemble it first.
I've a spark at all 4 plugs - assuming it's firing in right order. Battery gone a bit weak now so put it on charge.

It's a 16v, but still CIS so it is valid.
Also check my signature for a 'how-to' for a fuel pressure test guage.

Something to try this weekend.
One big problem I've seem to have encountered is the very slow turning over of the engine even with what I thought was a good battery - I think this is part of my problem as the engine is not creating enough "suk"
Not sure why this could be be - I've checked the tightness of the connections and earths - May I've missed something 🤷🏼♂️
I had a good couple of backfires earlier when I tried it which i guess was a good sign of some activity in the engine.

with no fuel in the lines starter burnt out fitted
1.6d starter backfire is good you have fuel and
spark therefore timing plug leads wrong perhaps
worth checking simple errors usually over looked

Tried a known good battery and swapped starter motor but yet still slow turning over - too slow in my opinion to throw the thing sufficiently to start up. Not even trying to catch yet we've checked for spark and fuel - both present 🤷🏼♂️
Engine turns over easy enough by hand with socket on crank bolt so fairly free. Not even backfiring now.
Rechecked all timing marks & HT lead orders - tried another rotar arm, dizzi cap
I'll take it to a garage near here and see if they can sort it as I've spent enough time and frustration with it now.
Unless there's something I've missed - please tell 😄

Check your Battery Cables, Positive to the Starter, and Battery-to-Frame-to-Engine for voltage drop. I have also heard of the Ignition switch as causing this as well.
If you place a Heat Soak Relay (www.cabby-info.com) yes I know it is for autos, but work wonderful for the manual starters as it shortens the run of the current, and improves your ignition switch life.
What do Divorces, Great Coffee, and Car Electrics all have in common?

Basically :
Got a spark and checked timing points and all look good
Got fuel squirting out of injectors when you lift meter plate up.
Problems :
Slowish to turn over.
Plugs dry when I take them out so is fuel not being delivered into the cylinder when cranking ? Is this because it's cranking too slow to create the fuel pressure ?
Not even trying to catch, no backfires
"Fed up to "top attic" as we say in Yorkshire !
I can get a mobile mechanic or get it trailered to the garage but I know it's defeatist but feel as though I'm wasting my time and it's been 5 years since it was last on road.

Slow cranking sounds like a poorly starter motor to me - provided you've got decent power and earth to it as Briano has mentioned.

all tight and not broken/frayed. Still sluggish turning over and now other spare starter motor is clicking now so that's probably not boding well - battery still strong though.
Somewhere back of my mind 🤔🤔 - my earth for engine goes to the support bracket of gearbox (under air box) - did I read somewhere this should be on one of the bottom gearbox bolts to engine ? Would it matter?
I've got another starter motor on order. If that makes no different then I am at a loss (for an amateur)
I can only keep going back of the basics.
