i seem to have attracted a problem with my gtv after i have driven it for a while doesnt matter if it is 5 mins or 5 hours it doesnt start up (just sometimes but seems to be getting more frequent) and to begin with i didnt have a clue why it was but have noticed what happens, when you turn the ignition to start it up there are lights on the dash and one is a in red in the speedo one and is a injector with spray, now if it starts this will go away after a few seconds but the problem is when it doesnt go away the car just wont start it will turn over but no spark. . .you have to turn the ignition on and off sometimes a few times to get it to go away before it will start up??? does anyone have any advice on what it could be thats causing this?

Crank sensor? Do a search on it.

It may be a red herring (or I may be wrong) but I think the injector light stays on if the immobilisor is activated.. Maybe your immobilisor/key code is not being detected by the car?

In these cases, I think the injector light in the speedo is joined by the alarm LED light on the dash flashing or staying on too, if it's not happy with the situation.

Have a look to see if that dash light is flashing , when the injectore light on the dash is lit. If it is, then it's an immobilisor problem. I think the aerial for the key code is behind the steering column cover, if you need to investigate it.

Immobiliser active is a key symbol, rather than the injector symbol?

I would get the error codes read, this should show why the injector symbol is staying on..

(but failing to start when warm will most likely be crank sensor as badgers nadgers said..)

Ah okay.. just a punt.

On the other hand, the TDC sensor failing doesn't make the injector light come on, does it? Chrissyboy says if he turns the ignition on and off, sooner or later the fault disappears and it will start. That's slightly inconsistent with the crank sensor failing when hot.

In some cases the car does it even when it's not hot...?

Mind you, my old TDC failure was on the 155 which doesn't have a very sophisticated leccy system (though it does have an injector light and that never came on).

after doin a bit of research on other posts with similar problems i think i am going to replace the maf sensor and see what happens after that
thanks for all your knowledge and help
