Fired up second or third piston up and ran sweet as a nut for around a minute then just cut out and died.

Omega General Help / 2.5 V6 engine fault update
« on: 15 November 2011, 12:15:15 »
More help please.
First a brief diary of event so far.
Aux belt tensioner failed and took out the belt. These items were replaced. (the engine did boil up but only lost 2 pints of coolant)
Engine started fine but cut when it got to temp. Leave for 5 mins restart ok then cut and so on.
Suspect crank sensor now replaced.
Engine started ran for 1 min or so and cutout and now will not fire at all.
Paperclip test shows 73 mass air sensor voltage low.
I've checked all the pipework around area where I was working when replacing the belt and can fine nothing obvious. All pipes and rubber conectors appear ok and there is nothing I can see hanging. All the plugs are conected. All the larger pipe clips are tight.
Any ideas would be appreciated.
Thanks Pete

I've checked the MAF sensor plug for a bad conection and all seems well.
Also checked all the vacuum pipes and conectors at the front of the engine incase I'd dislodged one but can find nothing to report.
The engine will not fire at all now following the initial start and stop after less then a minuets running.

Paper clip test done.
3 codes showing
1-2 start of test
7-3 mass air flow sensor voltage low
and the usual 3-1
Which one is the mass air flow sensor.
I did unplug the air intake pipe work to get better access. So are we talking broken wire or dirty plug conections or crackered sensor.

Read the paperclip test and watched the vidio.
Just looking for a clip and will post again shortly.
(Not so depressed already)

The tensioner pully exploded when the bearing failed and destroyed the aux belt.
The water pump seems fiine no noisey bearings and he belt is operating as it should do.

Help needed. Location Burnham on Sea Somerset.
I have replaced the aux belt and tensioner on my 2.5 v6.
When I started the engine all was well until it got to temperature. It then cut out. 5 mins later restarted fine only to cut out again and so on.
Checked here and all the simptoms pointed to the crank shaft sensor failing (now replaced).
On completion the engine started ok. As soon as the RPM started to slow down from initial cold start running speed the engine cut and will not restart (left for an hour before trying again).
Does any one live near by who can do a quick diagnosis or have a probable solution to the issue.
Thanks
Pete

Omega General Help / Re: Coolant loss .. Any help please
« on: 14 June 2010, 20:50:11 »
Thanks folks .... It looks an easy fix.
The "How To" is brilliant I even managed to understand it first time around.
I think the wipers will be vacating the engine bay for a while (big hands) or maybe just fat ones.
I'll have to find out if my trade account is still active at Mills.
As they say every little helps.
Just for the record I also have a small tool kit and a very large tea mug (Should do the job alright).
At least I know what I'm doing this week end. You just watch the weather turn to the worst now.

Omega General Help / Coolant loss .. Any help please
« on: 13 June 2010, 17:23:58 »
I have a water leak somewhere at the rear of the engine compartment of my 2.5 V6 CD auto.
I can't see where it's coming from
Are there a common problem areas that might give me a good starting point for my checks ?
Or should I just try a lump of Barseal ?
Pete :-?
