I have a Peugeot Expert 1.9 D and when I try to accelerate it seems like it’s hitting a limiter , and won’t pull anymore and releases a lot of black and white smoke .
Does this symptoms suggests that my injectors are bad ?
Thanks a lot for al the information .
Since I have described my problem I have found another spares car near me and I took from that car the fuel pump relay , glow plugs relay , comfort module , key and ECU . I have first replaced the fuel pump relay and when I switched the ignition on the fuel pump started priming but it won’t start , then I have managed to connect my diagnostic tool and the error present is P0340 Phase sensor , Coherence revs sensor at startup which I can delete but it would come back , I want to mention that I still don’t have any voltage present at the crankshaft wiring . After this I have replaced the ECU , comfort module and ignition lock and I checked the errors before cranking , the spare ECU had two errors logged unrelated to my problem which I managed to deleted and then went and tried to start the car . It didnt and now on this new ECU I have a new error that is logged in P1135 3 Piston Deactivation , short circuit to ground / o.c. Which I can delete it but it would always come back. If I replaced the ECU with my original one the error also changes to the P0340 and vice-versa.
Anyone ?
I have a 2006 Fiat Scudo 2.0 JTD with 200,000 miles that I’ve been using for the past year. In January, I started experiencing a peculiar issue with the van. While driving normally, the engine would suddenly shut off, prompting me to pull over. When attempting to restart, the temperature gauge would go into the red zone, and the car would only crank without starting. It’s important to note that there are no cooling system problems, and the engine never overheated.
To get the car running again, I found that disconnecting the battery and leaving it for 15 minutes would do the trick. This problem occurred about four times in four months, and each time the battery reset method worked, until yesterday when the car failed to start altogether. It would crank but without starting . Since then, I’ve taken some steps to troubleshoot the issue.
I inspected the in-tank fuel pump, and it appears to be functioning properly. I also checked the fuel pump wiring plug for voltage while cranking, but there was no voltage present. I replaced the camshaft sensor and examined the crankshaft sensor, which seems to be in good condition and responsive to metal when tested with a multimeter. However, there is no voltage at the wiring plug for the crankshaft sensor, and grounding it is not possible.
Furthermore, I inspected the wiring up to the ECU, which seems to be in working order. Additionally, I cleaned the grounding points and checked all the engine bay connectors by plugging and unplugging them.
I suspect the issue might be with the ECU or at least something related to this as it seems like the pump doesn’t get the signal needed to start priming diesel.
What else I should check or there are any know common issue that might be affecting my car?
