    Hello. I am the lucky owner of VOLVO S40 1.8 '98. My problem is that the car won't start. Earlier, after turning the key, something like a howling sound for a second was heard, as if the pump sucked in fuel, now it is gone. I left my car in the parking lot in the morning and started in the afternoon and went out after a second. Then he didn't fire again. The engine spins, but I don't want to start. The fuel pump is operational. I didn't check the spark. I will add that I changed the antenna of the immobilizer. I am asking for help with hints and suggestions, I am completely green and I am just learning. Greetings.

    Would it be best to do computer diagnostics? How does the immo control behave?

    Is the imo light off? and check the spark because there may be a problem with the shaft sensor.

    Normally you can write it, what does the injection pump have in common with the gasoline engine and the phone going out?

    Check if there is a spark.

    The immo indicator behaves normally and goes out after a while.
    Sorry for the mistakes, dictionary.

    Small offtopic. It seems to me that before starting the topic should be a small test of technical knowledge. After all, advising someone on such topics is completely pointless ... It's like logging into a gastronomic forum and writing a post: "after 2 hours of cooking, I took out raw meat, what's the problem? I checked that I had electricity at home, but I didn't check the oven is heating up. "
    And that it would be in accordance with the regulations. Connect the computer and see if you can see the speed and whether you have any connection with the engine control.

    Looking for help in the forum, and you have done practically nothing to solve the problem.
    But I understand that you expect professional help, so:
    - Use an oscilloscope to check the shaft and shaft position sensor including the harnesses, under load and short-circuit angle
    - check motor controller power supply, permanent and main relay
    - check the fuel pump relay and its control

Topic summary

The discussion revolves around a 1998 Volvo S40 1.8 that fails to start despite the engine spinning. The owner reports a previous howling sound from the fuel pump, which has since ceased. The fuel pump is confirmed operational, but the spark has not been checked. The immobilizer antenna has been replaced, and the immobilizer indicator behaves normally. Responses suggest performing computer diagnostics, checking for spark, and examining the shaft position sensor, motor controller power supply, and relays related to the fuel pump and engine control. There is a call for a more thorough technical assessment before seeking help.
