    Volvo Penta 5.7 no spark

    I was not present, but as they explained to me, computer diagnostics showed no errors and they had no choice but to check all the contacts. As I understand it, they just cleaned all the contacts they could find. Then a spark appeared. Therefore, no one knows what kind of contact was the cause...

    Volvo Penta 5.7 no spark

    Unfortunately, everything is difficult with Volvo Penta dealers in my region, they are now in high season. They just closed their offices and don't pick up the phone as well. who answer do not even want to talk. Answer one - call in May. So it is unlikely that the office secretary will be able...

    Volvo Penta 5.7 no spark

    I figured it was a circuit breaker on the + ignition wire, but since the + goes to the coil it's not a problem. I re-read a few more forums, and there was a person who also checked everything that was possible, but the problem was solved by replacing the ECU. Question, can Diakom flash the ECU...

    Volvo Penta 5.7 no spark

    This wire fell off, I covered 2, but this one did not have enough screws and I crimped it. Turns out it needs to be screwed on securely. And what is the button / relay next to the lock on the right? I never knew what it was.

    Volvo Penta 5.7 no spark

    Most likely it makes no sense to check the fuel pressure, it does not affect the spark. But I will order a pressure gauge and check when I have free time. It seems to me that the initial problem was in the ignition switch, yesterday I again wanted to test all parts and there was no 12V on the...

    Volvo Penta 5.7 no spark

    I don't know how to explain, but I think you understand what I'm talking about. The fuel pump has a black cap, like a bicycle tire. If you unscrew it, there is a nipple, like on a bicycle. I turned on the ignition and heard the operation of the pumps, but when I pressed this nipple, the fuel did...

    Volvo Penta 5.7 no spark

    The only thing I can't do is check the integrity of the signal wires from the sensor to the ecu, since there is no correct wirings diagran. I'll ask the dealer to print out what you mentioned earlier.

    Volvo Penta 5.7 no spark

    Thanks for the advice, today I was on the boat again and did the tests, I still don’t have a scanner and it’s too long to wait for it. Today there was no 12V on the coil, but it turned out to be a wire break in the ignition switch, this has been fixed. Now I see 12V when I turn on the ignition...

    Volvo Penta 5.7 no spark

    Good idea, looking forward to hearing from you. Since I do not have a laptop with Windows and for me a separate device is more convenient. I'll take an assistant for now, since it's extremely inconvenient to do it alone. And I'll go through the wiring, contacts, sensors again. I did not remove...

    Volvo Penta 5.7 no spark

    I put in new fuel 2 weeks ago, full tank. BUT! I don’t have a spark, I already thought about fuel too, but where is the spark? So I have 3 connectors near the right exhaust manifold, I don't know which one is diagnostic. I post a photo. Tell me please. I also have a question, is the crankshaft...

    Volvo Penta 5.7 no spark

    Hello, NOID light is £20 but I have never used them and want to know if they are all standard or are there different connectors? Could you recommend something? I read in the EFI instructions that if the nozzle does not work, then there will be no spark either.

    Volvo Penta 5.7 no spark

    I already checked for moisture, but no. I had an idea to check if all the wires are intact, maybe there is a break, but I can’t find a diagram of my motor. There is a similar one. But I have 2 wires coming to the ignition coil and they have power. And in the EFI 5.7 GXI circuits, there are...

    Volvo Penta 5.7 no spark

    Distributor dit not been moved. I have a new battery and I have a solar battery, so there is always order. The only thing I noticed is the oil pressure gauge, it shows 20 when the engine is off and rises to 80 at the time of starting. Could this be a problem? Since I no longer see other...

    Volvo Penta 5.7 no spark

    If the revolutions are read from the distributor, then I did not check the sensor on the crankshaft and the problem may be in it. Right? I thought that the rpm was read from the crankshaft when I saw 200rpm.

    Volvo Penta 5.7 no spark

    The motor started badly. The first time this happened in Spain last year, idle swam, after warming up it worked fine. The second time this happened after they washed the boat. Now I have sailed to the UK, it worked great. But the last start was difficult, I started the engine from the 20th...
