mk3 gti breaking down

[timmythedog]

Any ideas much appreciated. MK3 Golf gti, 8 valve 97/98. Breaking down intermittently and suddenly. 2 diagnostics have reported "no spark". New coil, and flywheel sensor? fitted. Problem still occurs. Seems to behave properly until it stops!!

Dizzy maybe? Try one from a breakers.

if you have replaced the rotor/distributor cap(centre spring can be deceptive and appears fine)ht leads and plugs/fuel filter/coil earth cleaned&apply copperslip to earth area&securing bolts.lubricate all ht leads(inside caps) with fine mist of wd40 from plugs to cap and to coil.earth strap from battery to gearbox corrodes and may look good from the top,remove sand lightly and copperslip before replacing and same for coil earthstrap(coil to inlet manifold).you dont say if the starter swings after stalling but if it doesent check the small plastic connector attached to your ignition(when you turn the key this part makes contact)a spring breaks this weak plastic unit and it can be a headache but it's easy to replace and cheap to but.
