156 intermittent start problems
I have a 2001 156 1.6 T-Spark. I have an intermittent problem starting the car, and I would like some advice on what to try next, without randomly replacing parts!
Problem: The car turns over but will not start. This can happen 10 minutes after the car was started successfully and driving short or long distances, or after being idle for any period of time. I can keep attempting to start the car, but it just keeps turning over. The only way I can get the car to start is to leave it for 10 -15 minutes, go out to car again and it starts perfectly first time. This is happeining probably 1 in 10 times, but it is really annoying, and delays me alot at times as I have to wait.
Things to consider: I have an idea it is a petrol problem, either an air bubble, air line, fuel pump, injector pump as I think the engine is flooding. The reason I say this is because the problem appears to happen more often when the car is on any kind of incline (engine lower than fuel). Allowing the engine time to rest seems to allow me to start the car. This may or not be the problem but it is a gut feeling. I have tired pumping the accellerator while attempting to start, and also avoiding it, but no success (i don't think you are supposed to do pump accell on a fuel injected car?).
No warning lights on the dash.
The key code light goes off each time I attempt to start the car, so I do not think it is that.
This will happen when the car is cold/hot so I do not think it is the crank shaft sensor that I see has worked in similar siutations for other people, but not ruling it out!
I hear the fuel pump kicking in, and allowing it to finish before attempting to start does not work, or allowing it to run a couple of times either.
History: I brought the car to a garage about this and they replaced the spark plugs, no joy. I think the car ran quite low on petrol once a couple of months ago, but never chugged or ran out. but that could be me looking for an answer.
your thoughts advice/guidance are greatly appreciated.
