getting her running

hi
i have recently aquired a 83 mk1 gti 1800 cab, and i could use alittle help
ive replacd the fuel pump, ignition coil, dizzy, all filters and fluids.we have spark, compression and air…..and fuel…sort of
now, when i turn the ignition on, the tach goes to 1100rpm and when you try to start it goes up to 1500rpm (engine not running obviously) and only turns the starter motor when the screwdriver is placed on it
then i noticed fuel dripping from the pump, so i replaced the copper o rings, but still drips a tiny amount.
i thought ithen it was going to be a blockage so i undone the fuel hoses next to the airbox and let bubbly petrol out (trapped air i guessed)
still nothing
really want to get it running and mot'd, any help peoplewould be appreciated

Sounds like a poor earth somewhere, or a faulty coolant temperature sensor.

iv been looking over it all morning, im starting to think maybe the ig coil was wired wrongly.anyone have a picture of theirs, wiring diagram or can tell me which way they all go on
thanks
scott

ignation coil

im certain its the ig wiring
so…5 wires
1 earth from bulkhead
2 (one black, one red/black)
2 (one black, one green)
 
also i guess its 1, 3, 2, 4 firing order??

grrr…still nothing
indicators work, as does horn….wipers not so
maybe they're from the same loom as the starter/ig coil??
theres always the possibility of a immobiliser? can't seem find one mind  

Try some easy start in the inlet trunking.That'll confirm base ig timing,spark and compression(valve timing)
Then you know its a fuel problem if it starts.The tacho does suggest earth problem,but if no star after above maybe HT prob(coil,leads,connections etc)
Lets know how you get on and if you need any more help bud

thought it was 1342, but i'm not sober just yet.

had to put it on hold till now, took all the seats n carpets out today to give her a good dry. tomorrow im going to go over all the earth points etc. overall its really solid, so im going to put the effort into her and use it till summer.
once iv gone over as much as i can, ill give her another go at starting and with any luck, i might have her ready for the mot by the weekend
if not, prepare for the barrage of questions  

ok i'm sober now. 1342 firing order!

oh and one more thing


DO NOT USE A SCREWDRIVER ON THE STARTER MOTOR WHILE YOU HAVE FUEL LEAKING!

lol good idea
im only just getting round to her now, had alot on.
think shes gona have to go up for sale soon as my times going to be taken up with my new business.must get her running or ill get peanuts for her
**walks off into the cold, armed with a little faith and some spanners**

thought i may aswell drop a few pictures in of her

sounds like a earth prob best thing to do is if u have jump leads. get 1 on the neg on the battery and clamp the other side on to the gearbox an see if it starts

hth

gearbox earth was already bridged to battery. i pulled the black box out the ignition and connected all wires.turns over, fuel pump powers up, ignition lights come on and we have fuel pressure.
????????????????????????????????????????????????????????

car now up for sale, havent had the time to put into her and shel just sit there.
