Thanks Peter, that's useful to know. Been cleaning and testing the injectors on my 94 Jaguar XJS today. Mazda 6 still running great after I did the decoke. 👍🏻
@@kennedysgarage3281 loads of it, very supprised as the car had only done 56k dual carriageway miles on good quality diesel; the main blockage was in that removable egr flow pipe in the manafold.
@@cebudave yes , it’s amazing how much builds up inside the intake manifold, well done for doing it though. Prevention is far better than trying to find an issue after it gets blocked up. Thanks for watching 🙏👍
Thanks for sharing. I have an 05 trafic showing low fuel pressure and started cutting out friday. Drive few minutes and it cuts out again. Very hard to start it. I changed the fuel filter but no better. This looks like it could be the culprit.
A late Friday evening rush video, didn’t have anything interesting lately & felt it might interest someone. Thanks for watching & commenting though Matt I really do appreciate it 👍😉
Ciao ho un primastar del 2004. Il motore si é spento durante la marcia e non sono stato capace di avviarlo. Portato dal meccanico con il carro attrezzi. Segna errore pressione carburante. Secondo te se cambio il sensore, ritorna tutto ok? Grazie👍
From memory I thinknits 0.6 volts with the key in rising to 2.4 volts ro tell the ECU ro power up the injectors ?,learned myself after my garage couldn't get it going,,new sensor and away it went !
Would you know if my fuel pump gause might be blocked? '07 Trafic with big bubbles in transperent fuel line near the filter. Engine starts then quickly stops. Priming the line with the bulb gets it going then driving seems ok although often at trafic lights lack of revs in first gear. Need to clutch it sometimes to get revs moving. No diesel leakage or smell of diesel under the bonnet. No error code nor any lights on dash. Fuel filter recently replaced and a good brand. Any ideas please before I go to all the trouble of dropping the fuel tank?? Thanks 😢
@antz123-m3f - air can be introduced to the fuel through suction so diesel wouldn't go out. I think the best way would be to check all fuel line connections (look for perished etc) then check fuel line for ruptures wears etc , if it's an air leak and not releasing diesel then it's not likely to be low down as the weight of the diesel in the tank pressurises and diesel should leak out. Have you changed your fuel filter etc?
@@stuungar3390 yes i recently changed the filter. When this intermittent fault happens, the engine first of all starts, then stops before I get out of the driveway. Then either the STOP light or engine light or maybe both come on. I even saw the glow plug heater light coming on despite my changing all of these very recently. Then I go and prime the fuel line and wait a few mins. Then try to start again. And it usually does, but only after maybe 20 or 30 seconds with starter motor engaged. Its like the engine is fuel starved. Then when it does finally start and runs, all these bubbles are in the fuel line up near the filter. Ill check the lines. Its just getting round to doing it without a garage hoist is going to be a pain in the arse literally!
Hi Peter, could this problem with the sensor cause the van to idle but not rev when warm? It does eventually rev but I notice the idle speed is low then gradually creeps up to about 800 RPM then it will rev ok, or if your on a hill and increase the RPM in gear that way. I'm waiting for a new accelerator pedal thinking it could be that. Thanks
If yours is the 1.9d engine, the most common issues with them running wise is EGR valves & Airflow meters. But both of them normally create fault codes, have you a EOBD code reader ??
@@kennedysgarage3281 yes it is the 1.9 thanks for the reply. I’ve blanked off the EGR and tried 3 different MAFS. No fault codes register. I’ve ordered a the pedal to see if that works, but as the fault seems to happen mostly when the engine is hot I don’t think it will solve the problem. It wouldn’t happen if I could increase the idle speed.
The pcm/ECU needs to know if circuit integrity is good so this applies to all sensing circuits but there has been 1 or 2 egr systems on Audi’s that had a 1 volt minimum that set fault codes, any more questions just ask, thanks David 🙏
@@kennedysgarage3281 hi Peter need advice please ...just taken a dpf off and cleaned it with soak solution...you have to tell the car when a new dpf is fitted ...do you need to follow same procedure after its been cleaned ? Thanks
I have a 1.9 Diesel Renault Trafic '06. Disconnecting the pressure sensor and probing with a volt meter, gives me 5 volts on pin 3 , when pin 1 is ground. Now, when I probe the middle wire of the connector, I get 15 mV D.C and not the 4.9 volts that you recorded. Any ideas? Thanks ? Do you think I should change the pressure sensor ?
It sounds like you have a broken signal wire or it is shorted to ground. You will need to do the same test at the ECU connector & see the results, that could be interesting 🤨 Let me know what you find please Jack 🤔👍
@@kennedysgarage3281 Hi Jack. I am only an hour away from your garage, so if I may, I'd like to book it in with you. I think it's either this signal wire to the fuel rail sensor, or, the fuel rail relief valve being faulty. I have a salvage fuel rail coming from the UK. If I could book it in for the next several weeks then I appreciate your expertise on sorting out my van's starting issue. Let me know and I will phone you. Ta
@@kennedysgarage3281 Hi Peter. The van won't start at all under it's own volition. But, does start straight away using a can of Easy Start. And once going, so long as it's still warm, can stop and start as per normal. Once cold, it's back to the Easy Start.
can i just put a new sensor in ours cause i know mine is bad , once done do you need to clear the fault or will it just kick in my friend thanks in advance
Yes, if you know the sensor is bad just replace it and it will work straight away. The fault will still be stored but will become a history fault once the ECU sees the issue resolved. Cheers Ian 🙏

Did not solve my problem but where o get p0191 but the explanation clears the way it works thanks
I have seen the pick up in the fuel tank to block too. Check for low pressure fuel delivery to the pump to confirm first 😉👍👍

Thanks Dave 🙏
If this is faulty will it stop the high presure pump from working
It doesn’t stop the high pressure pump from working but it does limit the ability it has to produce pressure if it doesn’t know the fuel pressure 😉👍👍
Nice video, could this also trigger DTC P0002 codes?
I would suggest NO, but I could be wrong. That would most likely be the inlet metering valve on the fuel pump 🤔🤔🤔
Thanks. May I ask where you get those volt-meter probes from ? They look really handy.
I got them from Diagnostic connections, but I do find eBay very handy too, cheers Jack 😉
@@kennedysgarage3281 Thanks Jack

Sounds like an air leak in your fuel system

Open off an injector pipe and see if you have any fuel when cranking 🤔🤔
