Title: Glow plug over ride / poor cold start
Post by: swiss on 20 March 2011, 23:35:52

Hi, struggling very much with the cold start... to the point where the Omega is gonna have to go the great scrap heap in the sky after failing to start out side the kebab shop. Luckily the kebab guy got his A4 and gave us a jump...

Anyway, it fires just fine after the plugs have run but struggles without... is there an easy, cheaty way to fire the plugs irrespective of the engine temperature or is this gonna be a dicking with the ECU job?

Ta

If your car isn't starting from cold I would suggest replacing the glow plugs

But surely this is my point; if the plugs fire then the car starts without problems. It's only if the engine is already warm enough that the plugs don't fire that it struggles. Therefore I was wondering if anyone has managed to rig the glow plugs to run with every start-up, regardless of what the ECU thinks :)

I know what you mean Swiss, the engine is warm, so the glowplugs are not "enabled". You are asking if a simple switch could be rigged, so at the push of a button the plugs would cycle.

So its not a poor cold start issue, its a warm start issue

A 2k resistor in series with the pump sensor will do it.
