Please help, 16V NON STARTER

[kenno 0]

Hi people

 

Hope some one on here can help me, I have a 1991 1.8 16v corrado, which have not had for long.

Right basically whats happening is it just won`t start up, there just don`t seem to be any spark or out. I have taken plugs out and gave them a clean up, also i thought if i took one of the plugs and leads off and earthed it on the engine it should spark when attempting to start, this did not happen on any of the plugs. can i earth it off anywhere on the engine as i might of been doing it wrong. Also when i took the furthest to the left spark plug out and tried getting a spark off, the engine started on the remaining 3. But when i took these off to get a spark off them none of them did

Hope some 1 can give us some advice on what to try next

 

thanks Kenno

are you saying the engine won't start at all with all the plugs/leads attached, but if you remove no. 1 cylinder plug (1 is always at the cam belt end on a VW 4 cylinder) then it will start and run on three cylinders?

 

Make sure the distributor cap and rotor arm are in good condition, no signs of arc-ing between contacts inside, replace if at all suspect, they are very cheap, the rotor arm may well be glued on, but can be crushed off with a pair of mole grips etc. Don't need to glue new one on.
