RE: SOMEONE PLEASE HELP
 

Like I have said to you many times you need to find out what you are loosing when it dies.
Spark?
Fuel?
Injection pulse?
Then we can help you more.

tech hi sorry im new to all this an keen to d.i.y
how can i tell check.???
can you give me some helpfull advice

RE: SOMEONE PLEASE HELP
 

You will need to get a fuel pressure guage and connect it to the fuel rail and monitor it while you drive.
You need to get a special tool called a noid light and when it dies connect it to a plug for one of the injectors and see if it flashes when cranking.(That is when it won't start)

That is what a noid light looks like.

Keep the top spark plug covers loose and check for spark when it won't start.

it will start but just wont run smooth or pick up revs

RE: SOMEONE PLEASE HELP
 

someone has recommended cam sensor?any advice?

RE: SOMEONE PLEASE HELP
 

Maybe but that will usually throw a code.
Also make sure no fuses under the hood in the fuse box are bad.
If there is one blown let me know before replacing the fuse.

RE: SOMEONE PLEASE HELP
 

ill check in morning tech thanks for help?is there any way to test if sensor is bad?where are fuel relays situated in t4?thanks

RE: SOMEONE PLEASE HELP
 

The nois light will help to tell if the Cam sensor is bad.
I believe the fuel relays are in the fuse panel under the hood.
