timing issues

[djtez]

i am having major problems with my newly built g40

i took all the timing cover plastics off and the car was just started first time few days back

took it out in my street today and its misfiring and complete lacking go about it

when just stationary it revs fine..
but when askin for power it really struggles

can anyone post up pics also of the position of there dizzy caps?

my timing light isn't flashing?
im using a gunsons supastrobe..... if anyone else knows hw to use it

Are you unplugging the blue temp sensor? If its not unplugged I dont think the light will flash from what I saw the other week when we were timing my car up.

the light will still flash with the temp sender plugged in, the only reason why the blue temp sender is unplugged is so that engine speed is correct when the timing is done.

i revved car over 3k three times with blue temp plug undone?

seemeed to have got the timiing set up ok?

but still seriously not going anywhere
its misin like hell

is there a common place for these to draw air ?

[hayesey]

I assume you've got the connector that should be on the timing light clipped to the HT lead on cylinder one?  If you have and there's no flashing light then either cylinder one isn't getting a spark or the timing light is faulty.

i got the timing done, the light was faulty used another light

still car aint drving?

next il try taking out injectors and testin them

[djtez]

is there a series of tests i can perform to trail and error my car.

e/g can i test the fuel pump?
injector test?
test if the engine is drawing in air!

is your cam timing ok could be a tooth out?
or there is a sensor unpluged/faulty somewhere.
I've noticed if i drive mine with the blue temp sensor unplugged i have similar problems. as tho the ecu is restricting the power somehow

if you drive it with the blue temp sender unplugged then it will feel like it has less power.  It's in service mode so doesn't make adjustments to the ignition timing for one thing.

You can test the fuel pump by connecting a fuel pressure gauge to the test point on the end of the fuel rail.

Or, a crude test of both fuel pump and injectors is to unbolt the fuel rail, then get a tray of some kind that's as long as the fuel rail.  Hold the fuel rail with the injectors still connected to it over the tray and get a friend to try starting the engine, you should see the injectors firing into the tray.  I would disconnect the ignition coil when doing this so that the spark plugs aren't firing because there'll be a fair amount of fuel vapour about!

good plan
thats tommorrows job..

how about testin if the engine is drawing air from somewhere else ?
would this affect forced induction like it would affect a na engine ?
