no spark!! after head gasket work

[KellyJones]

just done the head gasket, she wont start!
everything seems to be plugged in, the fuel rail has fuel (pressed the valve at the end of rail and petrol came out) just took a plug out and turned over with lead attached.....no spark any ideas? have checked the basics i think...:mad:

cam belt timing correct?

crank sensor connected?

[KellyJones]

will check the cam timing again just in case, it was fine when i fitted the belt, i done think the cams or crank moved during fitting, the crank sensor is fitted and plugged in.......if the cam wheels moved during fitting i would still expect a spark maybe?

Coilpack and MAF connector not mixed up!?

[KellyJones]

mixed up? can this happen?

[KellyJones]

I asume if i had the 1995 car i could have used the fault code tester under the bonnet?

Have you checked the cam and crank sensors are connected?

[KellyJones]

hi all seem to be connected, just spotted the aux drive belt is not fitted (alt/air con/pas) could that have anything to do with the issue?

[Dangerous Dave]

Could do, the ecu might pick up that the alternator is not doing anything, its probably worth fitting it to see.

And have you got the knock sensors connected?

[KellyJones]

When i removed the spark pug to check for the spark it seemed very dry although the fuel rail is full, maybe the ecu wont allow the injectors to work or produce a spark if the belt is dissconnected?

[KellyJones]

no spark from coil.....just tested....mmmmm

[KellyJones]

Just noticed that the plugs for the cam sensor and vacum body (the one the small vac pipes plug into) are the same and can be mixed up......guess what!! she fired up straight away, all be it with a massive leak from the exhaust manifold area! who cares its alive! thanks for all the help!

[Dangerous Dave]

Great news buddy, glad its sorted. Happy Volvo-ing!
