Omega General Help / Re: Problem Starting

« on: 26 July 2008, 23:30:42 »

Alright thanks guys, will look at all of this in the morning, but i think i will end up taking it to the garage and leaving it there until monday if i do get that one very last lucky start, as i really dont want to make more of a mess, i will watch over what happens and will be able to do it in the future, being 17 ive not had that much car expericance, taken two apart but theres a difference between taking them apart, and fixing/replacing thing.

Yea he deffinatly got his warning starts, luckily it just about managed to get him home, just spoke to someone who used to work for renault and she said to ask if the crank sensor is also called a Top Dead Centre (TDC) which (basicly) is the sensor that tells the engine where it is or something, and if it cant it just keeps firing but wont actually turn over? As a result to them gettings too hot and erroding (read something similar to problems with heat somewhere else on here)

Had a quick look on google for the codes, dont know if this is right but i think the light codes result in this:

Fuel pump relay
Coolant temperature sensor (voltage low & high respectively)
Knock control system

Is that right?

Omega General Help / Problem Starting

Just in need of some help regarding my old mans omega, i think this is the right section to post this if not mod please move.

The last week or so its been playing up not always starting first time etc, he got a new battery on it yesterday as it hadnt been changed in the 5 years hes had it. Still having the problem though, had the aa out twice today and both times they've not been any help. We have managed to get it started about 6 times today, but 3 times its been up to an hour before we can get it moving. Spoke to a few different people and have a simple knowledge of cars myself so i have a few 'guesses' if what could be causing the problem but i really dont know enough to actually find out the problem.

The things we have come up with are, fuel pump, not sure if its bust or what, maybe the pipes need blasting no idea. The AFR was brought up, personally i dont think it could be this but someone said they think the mixture is a bit rich, well i would imagine once its just been started it would be as we are having to floor the gas in a last attempt to get more petrol to the engine. Another idea we had was maybe spark plugs, hes got the 2.6 v6 model and when we got it started the last time i was revving it to about 7000 rpm and at very high revs theres a very low pitched hollow sounding bang, but not not like a back fire, dont know where its coming from, checked the exhaust but looking at it everything seems alright on it, not that id know where to look, but maybe something is miss fireing? Someone else said that because the car is sometimes run low on petrol when apparently it shouldnt be that the fuel tank might have some 'flakes' on the inside and when filling up the tank it maybe block the pipe becuase of this, and lastly he has been filling up the car at a different petrol station to usual and wondering if its dirty fuel etc.

Sorry about the essay, any input would be very helpful.
