Technical Engines Died

TDC sensor fault. But should cause no fuel past the injectors at the same time.

I just wonder if there's some interconnection between the cam sensor and the TDC sensor with that engine/ECU. Can't see why though.

Add coil packs, poor earth (most likely) connection(s) to coilpack. misaligned TDC sensor.

So basically fitting a new CamShaft Sensor will still have the same affect as its having now,

TDC Where would that be located?

Iv cleaned up the earth to the gearbox, where it bolts to the chassis it seems to be green where the wires connect to the terminal,

As my post about the cam sensor,
I was just going by the fault the other bloke had & the cam sensor seemed to off worked out good for him,
With pretty much exactly the same problem im having.

Yeah, it just puzzles me as to why it worked.

If crank sensor (aka TDC sensor, aka rev sensor) fails, it will fail to fire the injectors, so no fuel past them (although the fuel pump will still prime, so there should be fuel in the fuel rail) and there will be no spark. They're pretty temperamental, at the best of times, and I suspect that there are some fairly worthless Chinese copies knocking about (QH are now a Chinese company ).

Location is on the timing side of engine, at crankshaft level, usually to the front of the alternator pulley (which will have "teeth" on it) but sometimes above. If the sensor isn't close enough to the teeth (gap is usually 0.5 to 1.5 mm) the sensor may be OK, but it'll just fail to "see" the teeth and won't send a signal to the ECU.

I have fitted a new crank position sensor, it was located to the rear of the engine near the starter motor

Got the Camshaft sensor it will be here tomo so thats something to do, lol
The joy off cars,

Had it all checked over & its definitly something electrical

checked over the wiring loom maybe 3-4 times now & cant find anything,

Just wonder what it picks up off.......... if no joy with cam sensor, worthwhile seing if whatever it picks up off -- maybe a pip on the flywheel? -- is still in place.

I have vague memories of a PPC staff member snapping such a thing off when using it to lock up the engine! Of course, were it not there, the engine wouldn't run, but a glued on, snapped off one might have stayed in place till now. Oh, the horror!

Sounds like a complete horror that does lol,

As iv got the cambelt cover off i thought id give the cam sensor a spray with WD40 to clean off the gunk & the engine started to do more than what it has done, it wanted to fire but then didnt lol,

Found out what the problem is, Just need to get the part.

It is the exhaust side pulley, the keyway had snapped off Which has made the timing out.

At least now you know how to fix it. How much is it going to cost you?

 

[Bullitph29]

£15 for the pulley delivered. Need the beast back on the road asap got a job interview to go too

wont valves have all got bent again though?

 

[fingers99]

Etc.

I'm worried that it happened: folk think that the little woodruff key locks everything in place, where, in reality, it just locates it. The torque on the bolt do the job.

Damage to keys is usually a result of someone not locking the cam up with the proper tools (relying on the belt, etc).

Yes mate you are correct, just found out it bend most of the valves, which is rather annoying say the least,

Dontknow how is was done so i cant really comment, i guess that what you get for buying a car with no paper work.
