Engine won't fire?

matt80

Hey everyone, I've been having an issue the last couple of days with the vec C, when starting the car it would sometimes cut out unless i accelerated and then when i drive along I can feel the car judder, like it's missing i guess.

Now, this morning when i got into the car to go to work, the car wouldn't fire at all, it does try to start but it just won't.

I'm wondering if this could be a coil pack problem? any advice will be great

Thanks in advance everyone 🙂

check the spark plugs /.. also i had same problem on a veccy .. i unplugged the precat sensor ..and that cured the kangaroo and lack of power ..
think the pre cat sensor is the fuel mixture

spark plugs might have the wrong gap ..

Have you got an EML light on? Error codes?

First check Fuel Pressure - Touch the centre pin in the valve (looks like a bike air valve on the fuel line). Fuel should shoot out and hit the bonnet. Could be FPR (Fuel Pressure Regulator). Crimping the return fuel line will also provide pressure. Use adjustable moul grips but make sure yo dont pinch the pipe fully so it stops the return! You just want enough to increase pressure.

Second check spark - Take coil pack off, plug it it & plug spark plugs into it and rest it on top of the engine (providing you have metal cam cover). Get someone to turn engine over. All four spark plugs should spark at the same time.

Third check air - TB coked in crap, airways blocked etc.

If all three check out then could be more serious. Hope this helps :thumbup:
