astra h 1.7cdti turns over but wont start

[dafdiagnos]

if the vehicle starts with brake cleaner then you will know the timing is in synch & it will be down to fuelling trouble. you need to oscilloscope test the cam & crank sensor signals at the ecu pins for good waveforms to make sure it's not wiring trouble

[carsolution]

Take a look at the ECU, it is located behind the whell and in that space it takes a lot of water.
Open it and see if you have water signals.
Remove the injectors connectors and see in the connectors if you have signal to open the injectors.
You can check it with a led, The supply for the injectors comes directly from the ECU, if you dont have signal start considering you can have ECU damaged.

cheers for that but have checked all wiring and is fine i still need to do the brake cleaner test!!
its driving me mad....think im gonna have to check receptor ring aswell although i would of thought it would be pretty unlikely?!
cheers

engine code should be in service book and on the engine too
the ecu is at th top of the engine the edu is at the back of the engine at o/s drive shaft or there about's
if you can give year ect it will help us to help you
and brake cleaner will start this car if sprayed down the inlet manifold
but only briefly as long term may cause damage
post full details
remember we cannot help with no info
as we cannot see the car and diagnostics is one thing but doing it remotely is another
post full details no need for vin or reg
just engine year ect

i have put this in my thread but here is my engine numbers z17dth 01521093 hope this helps !!will do brake cleaner test tommorow and let u know the outcome!! thanks for your help man i need it!!

If it dont run on brake cleaner m8, your engine is mechanically wrong, id of thought!!!!!



I stand to be corrected?

agree, but
a) racing-snake (think) always uses it
M-H-M prefer 'Easy Start' - causes more damage and smells nicer
b) try towing in gear 1/4 mile then brake cleaner to 'warm' up the engine
acts like an air compresser

[teuton]

check compression, do a leak downtest!!

hi have put easy start in and still wont start what could this be...

Your engine is ~~~~ed, you need a new one.

remember to inhale that Easystart, good stuff
