xe wont start

[dave beety]

i got a c20xe in my nova and some times it starts and some days it just dont wont to no and gose to start and then wont any clues guys
and it has a little miss fire to it as well if u turn it off when u got it running it wont start and turn over and over

[craig green]

I would 1st look to check the fuel pump relay & the cank sensor.

[dave beety]

i put a new relay in bud ill have to get a new crank sensor any think els u could think of as getting redly to scrap it lol

[craig green]

Does it turn over OK? Maybe flash off the fault codes, chucking new sensors at it will be costly. A new crank sensor is pointless if the loom wires to it are fried (if you understand??).

[dave beety]

not to shore how to do the codes bud

[John]

was it originally a 1.0?

[dave beety]

1.4 sr bud i have a seh 130 lump in it then put this in it

[craig green]

So is it not running at all since fitting the XE?

Try unplugging the AFM. Maybe find someone with the same engine & try there ECU, AFM, coil & such.

Hows the rotor arm? Are the plugs gapped properly. I've had non-starters that went when I gapped the plugs down to .6mm

[dave beety]

its a coil pack engine it sparks and fuels cant work it out lol

[craig green]

Gap the plugs down in that case.. Easy & won't cost.

All timing marks line up? Dont trust the bottom pulley marker though. Either go by the crank sprocket (dot) or if removing the bottom pulley & cover is too much hassle, put a screw driver down plug hole 1 & find TDC winding it over by hand. Yhen make sure the cam pully notches line up with their markers.

[dave beety]

ok will do ill try to moz if not what do u think new motor or some think

[Sloth]

no, get a proper mechanic with decent xe experience to look at it.

[craig green]

no, get a proper mechanic with decent xe experience to look at it.

easier said than done. Paying someone to scratch their head for an hour isnt cheap. There is more knowledge on here than many mechanics have, But you could be lucky with a garage. Bit of a lotto tbh, even at Vauxhall dealerships.

[dave beety]

dont no if u guys get it when u ask mate to help and they say they will and never turn up like u drop things for them all so had a look on mig web some one said about idle control valve but dont see how that will do any think to it

[Sloth]

he aint a mate. if someone asks me to help i do. thing is without having it infront of me i cant diag anything.

[dave beety]

yea very true ill try all the things u guys said to if not will be on herte to moz lol

[dave beety]

is the coil pack wiring diagram different to a distributer one ?
