V70 stalling won't start help

Jfk1975 · Jun 22nd, 2018, 02:43

Hi I have a V70 2001 2.4 n/a automatic
Car was stalling when slowing down then only starts with foot on accelerator and won't idle just dies.
Work I have done since then is replace fuel relay, spark plugs changed, fuel filter and had the etm sent away to BBA reman who bench tested etm and found nothing wrong with it. There is a noise of the fuel pump priming when turn key. there are no leaks on vaccum lines and have replaced air mass sensor recently still no joy. Is there anything else I can check the car was running fine when I bought it had discs and pads replaced and new timing belt kit since they were done it has decided to die on me lol any help would be great thanks.. sorry there are no codes shown on dice.

Classic fuel pressure regulator symptoms. Check the fuel pressure at the rail against specs.

Was the ETM just tested?
When I had this on a friend's car (same engine) we cleaned the ETM and associated pipework with carb cleaner until spotless, issue fixed.
Have you read the fault codes with VIDA?

Hmmm, no codes, ehe ? That makes troubleshooting interesting. Is it possible that the air filter isn’t sitting correctly in its mount? Don’t think that would cause this but...

Also maybe the air pipe to the ETB came loose? Or the charger hose connection at back where it meets turbo could have cracked?

The rear o2 sensor could cause issues like this but it would likely spit out a code too. Although I have heard that sometimes the codes are slow to come.

The ETM was bench tested and reported no faults had cleaned etm before sending away to see if dirty etm was problem. Have checked for fault codes and there is none and all vac lines are ok, can also hear fuel pump priming when key turned. Installed a new battery as old one was done but no difference to problem

Haven't had time yet to check fuel pressure which is next on the list. Annoying that there isn't any codes.
