HI all well my car had to be brought home today on a back on a lorry.I was driving down the motorway when i lost power and then the car cut out so i got to a layby and tryed to start it and nothing.When i did get it running again it sounds like its a diecal car not petrol and when the car is running there is no power and has to be revved to keep running.Well i got some codes and i think iv got them right

01150500150301050015030115050

[Marks DTM Calib]

can you re-read the codes as there is a bit of an error in there somewhere

0115 Coolant Temperature Voltage
0500 No Vehicle Speed Signal
1503 Immobiliser Wrong Signal

Sounds a lot.....is the battery ok?

[Miggy24]

Hi yes the battary is fine but will redo the the codes.Its abit weird that this has happend after i put the temp gauge wire back on cuz it took afew times to start it then

[Miggy24]

Just redid them and got this
P1503      Immobiliser Wrong Signal

It does sound like too much of a coincidence doesn't it.

The temperature gauge shouldn't have any influence on the ECU temperature sensor but something changed while you had your hand down the back of the engine reconnecting it.

First thing to consider is whether the previous owner had a problem and found that disconnecting the wire to the temperature sender somehow made the problem go away

I would be looking for damaged cables, poor engine earth wires, damaged connector on the blue sensor?

When I lifted the engine out of my last car I thought I had disconnected everything. With the engine half out I discovered that the clutch hose was still connected. I couldn't see any damage but 20,000 miles later it failed 

See if anything looks as though it has been strained, there might be a connection that stops working when light pressure is applied.

If the cambelt has slipped a tooth could this be the course of it

I doubt it. Have you tried starting it again Rory. With a 1503 I would expect the EML light to flash whilst cranking the engine

It does actually sound the way my vec went,when that skipped a link,it sounded like a diesal and you really had to rev it to keep it running,but still cut out. :-/

Hi Rob yeh i have when the engine is cold it will start no probs but after 2-3 times of trying to start it it takes longer and longer to start

My bets are on the belt. :-/

Wouldn`t account for easy start from cold, then struggle after  :-/ Rory, does the engine still clatter when you start it. If it starts I can`t see why you`re getting the 1503. I`m assuming the EML isn`t flashing on cranking then?

[Miggy24]

Yes Rob still sounds bad when started.And Mark how can i find out how to line it all up 2 see if it has jumped a tooth

Mine still started fairly easy rob,weather it was hot or cold,just couldent keep the bugger running.

[RobG]

Can you describe the noise. Whereabouts in the engine bay does it emanate from :question

[Miggy24]

No light is not flashing when cranking
