    Car won't start.....beginning to look expensive !

    Just to let you all know I've been having problems with the car this week, went out on Wednesday to start her up.....turns over fine just didn't want to fire.

    Did the ususl, called RAC who sent a guy who was obviously knocking off as he simply spent 10 mins checking fuses (I'm not by any means a mechanic but even I'd already managed that) and turning the car over before asking where I wanted it towing.
    I declined his offer but agreed I'd call back if I wanted it taking to a garage.

    Yesterday was spent with a (cheap local) auto-electrician checking the ususl, fuel pump (ok) fuses (ok) when he had finished he said I had a problem with the immobiliser.

    Fast forward to today and had out a (bit more expensive/not so local) auto-electrician who specialises in immobiliser faults, he came with all the gear, plugged it in and came up with the following.....



    He also said that the ECM 'could not be found' (whatever that means), and said it could either be a wiring fault or the ECM could need re-flashing.

    Have any of you ever had anything like this before ?

    The car is now booked in to be collected by the RAC Monday at 0830 and taken to Carpenters, an Independent Volvo Specialist (est 1934) who say they should be able to tell me what's wrong by Tuesday lunchtime.

    http://www.carpenters.co.uk/

    As I'm a glutton for punishment I am offering a very small and extremely cheap Volvo related prize to whoever comes up with the nearest diagnosis/cost for this to be fixed.....over to you !

    It's a 1998 ME7 it's a new suggestion that the throttle body sensor could be the cause.

    I had a fault many years ago the old girl wouldn`t start and called a local garage to find the fault, pluged his bit of kit and said the ECU is f##ked because he couldn`t connect to it.

    So I called out a local indy volvo garage and he pin pointed the fault to the MAF which when changed the old girl started

    I think the your indy volvo garage should pin point the problem.

    Shame I couldn't be more help. I doubt it would be the throttle as there would be warning signs and it would still start.
    And I'm not sure if you can play swap the ecu with ME7 as its coded to everything else in the car.

    Fingers crossed tho mate, she'll be in good hands and hopefully there'll be a quick and not-top-expensive resolution.

    Keep us posted mate.

    Nope, all checked and working fine, immobiliser is seeing the keys, just not communicating with ECM.

    if its the ECU thats at fault get a second hand one doesnt matter if its auto or manual, Volvo will reflash it with original software for £78 all in. As some one already said if it was the anything to do with the throttle you would have codes and a light dash, your ETS and ENGINE lights would be on.

    The reason I ask is that whilst my small OBDII code reader did not pull off a
    P1670 code (only a P0300 misfire code), the code reader at the garage (Smartbox) pulled off the following two codes:

    At 5;21pm - TOTAL CODES 001
    IMM 321 "Initiation signal from engine control module (ECM), signal missing"

    Then on a second try at 5:26 - TOTAL CODES 001
    ECM-720A "Immobilizer communication"

    The good news is that the mechanic wasnt convinced and said that sounded like the engine was just flooded and decided to try tow starting it - IT WORKED! after switching off it restarted with the key ok.




    Now this IS interesting.....

    The RAC guy asked when I last started the car and for how long I left it running, I had simply started it and turned it staright off, he also reconed it was flodded but couldnt get it going again by turning it over.....I've also heard these engines don't like being started and turned off straight away.....just gotta find someone to tow start me to find out !

    If the car is flooded take the spark plugs out and leave the car for an hour or too and then put them back in
