Starting issue. Intermittent.

[Anto9361]

Saxo vtr 1.6 99 plate.
Really puzzling me now. Starting to think whether I should just get an auto electrician. When plugged in shows no codes.
Basically sometimes starts first time. Others can take up to 10 minutes of constant cranking. Everything sounds fine. Engine sounds sweet when running.
Had numerous new parts, or scrap yard parts.
Throttle body complete
All sensors.
Immobiliser taken off.
Fuel pumps working fine.

Any ideas?

Sounds like a bad earth.

I've checked majority of earths, and place a earth from engine to chassis

You checked you have spark etc I take it? I mean you must given that sometimes it starts but ya know. Is there a strong petrol smell when it eventually starts after dry cranks?

Try turning the key to position 2, leave it for a minute or so, then try, see if that helps and let me know.

I know it's unrelated, but I have exactly the same problem in my BMW, and for some reason, leaving it in pos 2 for a minute seems to help, which I'm thinking is fuel pressure, just don't know why. Dunno how a saxo works though, so maybe not.

I'll try that tomorrow, and yes strong smell of petrol

Car still the same. Sometimes hear Icv going nuts. But car shows no codes.
