22R-E economy/starting drama's

Hey all, my first post on Toymods so be nice 
I currently have my mum's old RA65 auto as a daily driver that needs to last until the end of the year or whenever my Datto project is on the road.
Basically, my mum cooked the motor a few times and my dad recently replaced the head gasket trying to sort the coolant loss/overheating drama's - Ever since it's been getting only 200km to a tank and takes ~2min of cranking to start when cold.
Now the motor does also have low compression in two pots (rings, I've checked), but it did prior the head gasket change and still got over 300km to a tank & started fine, albeit overheating within 5 min.
now that the radiator & head have been fixed, the temp issues are all sorted, but I'm theorizing that my dad in his infinite wisdom screwed up some sensor or possibly something coincidently died at the same time.
What should I be looking for? could the cold start injector be running backwards if he hooked up something wrong? this would explain the hard to start when cold + bad economy problems as a guess but where to look I have NFI.
I have looked at the wiring diagrams for the 22R-E under the tech docs section but as far as I can see it all looks fine.
No, I'm not fixing the compression as it seems irrelevant IMO and the car is getting a 1G-GTE conversion done on it once the datto is on the road so wasting cash on the 22r is not an option
Any help appreciated
Ash

I don't think these dinosaur motors can ever be expected to return decent economy. I drove a well-maintained 22R-E Hilux to and from Melbourne early this year and got no better than 450km from each 70 litre tank of PULP 
They also seem to be utterly gutless. Had to use 4th gear on things that were barely bumps, let alone hills, on the highway

I'm getting between 500 to 550 from my RA-65 with its 22R-EC and it isn't pussy-footed around.I use lead-replacement fuel with-out any probs and put a bottle of injector cleaner through it every oil change (5000)I think there is more wroong then just the enrichment jet if you r only getting 200

Yeah the economy on the engines is pretty shit the best i acheive is 15l per 100km more likely around 18 though, don't have the performance problem thoguh, mie flys prob got to do with my car only weighin one tonne and lots of low down torque.

i dont know if this is relevant at all.. but i only get just over 100-120ks out of approx 20L of PULP from my 2 litre 18R-GEU.. It is running the 22RE afm and quite similar EFI setup and is still a bit rich low down in revs, but is this just the kind of economy to expect from a thirsty late 70's 'revvy' motor on standard EFI?

townsville eh.....
u gotta remember; auto, 2.4l, early 80's/mid80's engine (a bit tired by now) , power steering, air-con (probly). a good combination for poor economy.
but if it has changed significantly since the h/g was replaced then some wire or hose may have been misplaced

Interesting. Mine (stock, tired, tho with 2" exhaust) pulls up hills in 5th no problems, and that's with a tall diff. The one thing they're really good at.
