Vauxhall Zafira car won't start

Disconnect the Air Flow Meter and try to start it.
any faults in the AFR or wiring will now be disregarded by the ECU and it will use it's memory for the readings.
At best this will get the beast to run.
What I'd like to know is what diagnostics are you using?

Thanks for quick response but I've tried unplugging mass airflow sensor it is a new one I put it on last week also gettin code p0004 fuel volume regulator I'm using an OBD bluetooth connector and the app obd doctor on my samsung tab also works on elm327 terminal but still same codes on both

Well I'm looking at the Vauxhall TIS manual right now.
Your model/engine type and year (thanks for the comprehensive information by the way)
And none of you codes are in there!
Now I've seen this often enough,
Even Snap On's six grand scanner got handed back for being next to useless.
Whatever the codes you are getting as you state you have thrown cash at it.
Throw more,
Buy "OPCOM" or tech II software.
£20-40 on Ebay/
Just this week I've had on a Corsa "No comms",using an Autella hand unit,
works most of the time.
Minimal information using "Delphi 150",
usually very good.
And access to everything using OP COM.
Which I should have plugged in first.
Buy one.
read codes,
At least the codes will be Vaux.

Hey ho,
back at work,
and referencing Auto Data your correct,
P0104 MAF circuit intermittent fault makes me suspect the wiring from the ECU to the MAF.
So eyeball inspection and if capable load test the wires.
And your p0004 would seem to indicate an open circuit or short to pos + on the on the regulator solenoid control circuit wires.
So it looks like you'll be stripping the insulation on the harness.

Hi thanks for responding is the wiring harness the one that runs directly at the back of the coil pack and connects to the fuel injectors?

Connects everything from the fuel injection system to the ECU.
Focus on the AFM,
strip off all the outer covers until the individual wires/insulation is open fro the AFM to the ECU to eyeball inspection.
I usually clean off the outer insulation of each wire with Panel wipe,
Then with a very good light I EYEBALL every MM for insulation damage or telltale bright spots where the inner wire is exposed/
It really doesn't take much,
One tiny strand of inner wire can short out and screw up a sensor output signal.
The fact that unplugging the AFM to no effect tells me The ECU is still getting a signal so not using it's default settings ,
Wires are shorting across.
Same with the fuel solenoid.
Slow painstaking work.
I have taken entire wiring harness of the vehicles in the past and sat at the work bench with solvent and cloths and one of those magnifying lenses/work lamps.
REALLY GOOD LIGHT needed,
Finger sensitivity helps as well,
As stated one tiny strand can be felt as it snags your finger.
Last one I did at the bench I quit counting after 8 or so shorts!
Repaired the insulation refitted the harness and it started with no MIL,
no faults stored and none since.
Good luck.
