Hi there guys,

I picked up a 944 on the weekend.

It was owned by a lovely couple that lived in the middle of no where! They didn't know much about cars but loved the 944. They have had it up for sale for a while and on Saturday I went to view it, when I turned up they were running round it trying to get it to start as it had cut out on them a few minutes a go (I know what people are thinking) We looked around the bay and thought they'd flooded it. It had obviously been running as everything was still hot/warm.

We eventually got offered it by them for a grand which was an offer we couldn't refuse as it was a very rust free shell.

We have now since got it home and are trying to get it running again.

Here are the problems/symptoms we are getting:

No tacho bounce
Fuel at rail but not injecting
no spark

We've looked through guides for the speed and reference sensor. These have come back within the tolerances for healthy ones.

The DME relay has been checked and is working fine we even swapped just in case.

The signals from the Ref and Speed sensor are getting to the ECU also.

I have been told to check the immobiliser but that seems to only cut the cranking of the engine as it seems to be an aftermarket one.

The only thing I can think left to try is getting the ECU tested which is proving is going to be quite expensive if it turns out it is ok.

I was wondering if anyone is local that maybe able to pop by an evening/on the weekend just to double check/bring over some bits to try before I end up spending garage costs and ECU checks - I know it is a bit cheeky but I will give beer money to anyone willing to lend a hand.

Sorry about the long winded story but any help would be great!

Here are a couple of photos for those who just want to see photos [:)]

What variant is yours? Not an S by any chance?

2.5 8 Valve, Lux should have put that in the original post.

Glenn put me off the S after meeting him at Phoenix Green

Oh did he now!

Sorry I can't help, it's just that I have a spare ecu you could have tried.

Oh right, that's a bit annoying!

Yeah... have also been told by many others not to get one so I stayed away when looking... [8|]
 
Darryl, I don't know what you're being quoted for ECU "testing" but a replacement Lux ECU off of eBay is in the order £75-£80. It might be more economic to buy one, try it out and then sell it on again if it turns out not to be the fault. Just a thought.

Now bear in mind that I am not "mechanical", however, despite your testing the symptoms still sound awfully like a speed / reference sensor problem. I had an AA man test mine when it went wrong and he swore blind that it was "fine" after being all over it with a meter and that I had "an ECU fault". My car was fixed by replacing the sensor.
 
290843422968 eBay item no. £100 buy it now free post, as Glenn says if not needed sell on or keep as spare for a just in case which is why I have one in the garage.

Glenn sometimes talks sense. [:D][:D][:D]

Thank you Glenn, well I told my step dad about the ECU this evening and he's going to strip it down to have a look at the circuit board for any obvious signs as he's a bit of an electrical genius lol

That's interesting you say about the sensors coming through as fine on the meter but actually being the fault...

Testing the ECU is £30 and a refurb is £195 including the testing with a life time warranty. Not sure whether that seems good to you guys or bad?

This is very true and I've done it in the past but trying to save some expense where possible for the inevitable problems lurking MOT time!
 
Hi,

I'm in guildford, have you checked your crank position sensor and the other one next to it, sorry forget what it's called. I had a similar problem with my lux.

You need to check the resistance, see clarks garage guide, for details but its very easy to do

I thought my issue was ecu, bought one, but no change. The sensors are cheaper to replace, just!

Spence

Ignore,
Whoops should have read your post thoroughly [&:][&:]

Well "sensor" technically. The S2 has a single combined sensor that does the same job as the two in the Lux.

Hi Spence, yeah I have checked the resistance there, both seem spot on. We've gone over the ECU this evening and there are no obvious signs of wear so are going to get it tested to make sure.

Oh right I see. I'll get them looked at then if all else fails!
 
Immobilisers should be multi point, starter/fuel/ignition but even if they are they are not always wired that way. ECU faults are not unknown though.
 
My immobiliser is only cutting the starter.

I though crank shaft sensor but it was giving the right ohms and voltage when we tested it
 
Nice colour!

Odd that it had been running before you arrived....must be something straightforward, you'd hope:

No spark....have you looked in the distributor? Coil?

Has it stood for a while....this is not due to unleaded petrol "going off" with time, I suppose??

The coil and injectors aren't getting sent power, yeah it's been stood for a year so more than likely something has become weak over the time.

The lack of spark is stopping it run, otherwise I'd be swapping the fuel. It was running on what was in there though.
