The project Golf will not start.

Its been stood for 2 years, and started for the first time since storage around a month ago, using the battery off the daily. "Great" I thought. "Whack a new battery on and thats it". I noticed that the fuel pump didnt prime when i switched the ignition on, but it started/ran all the same. Ran for around 15 mins. Started it for a second time to make sure, no problems.

Fast forward to today. I bought a new battery for it, fitted it and wanted to show the Mrs that it actually ran...

Wouldnt start.  :embarassed:

Again, the fuel pump will often not prime when the ignition is switched on. The car will fire almost straight away, then stall as soon as the key returns to position 2 (running position). Its almost as if the MAF is disconnected (all connections are clean), however it will continue to run only if the key is held into position 3 (starting position). It even revs up fine but I cant drive whilst holding the key into position 3!

I checked the obvious - loose connections, missing connectors, petrol (i even topped it up with fresh stuff), the only thing i noticed was a lack of knock sensor (its an early PB engine, and looks like nothing has ever been fitted, the block shows no sign of anything being mounted to it). I also noticed the ISV buzzing occasionally when the igniton was switched to position 2. 

Why wont it start now but it started beautifully a month ago... and NOTHING has been touched!

Advice?

Ignition switch.

easy to change.

ok, where and how?

take off steering wheel,
take off cowling,
take of stalks, unplugging as you go.
slightly tricky bit, if its got a larger spline steering wheel boss you'll need to remove the collar. if not undo the allen key headed bolt and slide the metal surround off the steering collar, which holds the ignition switch.
there is a little screw to undo to take the ignition switch off.

thats pretty much it, may vary slightly from what i just said but thats the essence of it.

ta very much!

you gotta get a knock sensor on it, the ECU wont advance the timing otherwise!  Sounds like it wasn't a PB block at all, but a DX or EV K-Jet block.  All PB lumps have a knock sensor!

the block looks very similar to the 90 spec one i have, earth points on the head are in a slightly different place mind.

the wiring which the knock sensor would plug into does exist (there's a connector there), as does the hole to mount it. judging by the condition of the connector and the hole where the knock sensor would mount, i dont think its had one fitted for a while if at all.

hmm. 

best place to get one?

yep like i said, it'll be a k-jet or carby lump.  all 1.8 lumps are identical
scrappy would be where I'd look, look at any 4 pot VW/SEAT/Audi 8v lump.  I put a 2e one from a MK3 on my 1.8 block

edit: you'll want to run a tap down the thread, and clean up the mounting face till its proper shiny else the sensor wont get a good readng and/or your torque figures will be off, the torque setting is very important!

Had this with my golf over christmas but just got a compete steering column with ignition from the scrappy as i never had a puller!!

be carefull holding the key for the engine to run tho because if your starter stays engaged like mine did it soon chews the starter pinion to bits!!
