Found twin relays in trunk. Tested pumps both work. Switched relays same symptoms. If I remove the right relay car stalls in 2seconds. Replace it and remove left relay car starts runs doesn’t stall but dash say fuel shop message. What’s wrong ? Car has 26,000 miles
Without a code check its a bit hit & miss, but to my knowledge its one of the pumps & a bad reply. You need to get it on the ross tech to check the codes, again of hand if you get a code P0203 thats a faulty relay.
Get the car on the computer that way you will know for sure, once you know the error code do let us know to guide further.
Have you checked all the fuses, if you electrical minded I can send a tech drawing of the fuel system ...

Has the car been parked outside in rain recently ?
How often have you cleaned the front scuttle drains ?
I’d be looking at the front carpets for dampness in a UK car the passenger .Under there are more relays some part of the keyless go .
Also try just the key you have not said how you started it ?
Bat fob issues need eliminating as well re the immobiliser , so try new bats in the fob .Then check the immobiliser ECU / control box - damp , connections etc . Feels like an immobiliser ECU issue .......with out any codes .

Ok code P050A cold start idle air control valve & P2279 are to do with idle air control valve & the MAF sensor 2 off these are located under the air filter the codes indicate a leak in the air intake system
The best thing to do is a smoke test this leak could be anywhere from the turbos all the way up to the air box, it could just be a maf sensor or a valve you need to check both bank 1 & 2, looking at the car from the front bank 1 is on the left & bank 2 on the right (dip stick side) it could be a split hose some where in the system.
If your familiar with engines I can guide you through how to do a smoke test if not its gone have to go to the workshop ...

I'll post up everything from start to finish tomorrow at some point & hopefully all will be ok, lets hope it just a sensor or 2 or just a hose split ...
if you don't mind me asking are you in the UK ...
