Hi volvotech did you find it? There is a sensor sat in the box with the ecu - behind the battery which I guess is air temp? Being a clever engine it must also look at the water temp too

Finally got the car back and it needed two new injectors (well refurbs) Apparently no2 was pi**ing fuel and no1 was on the limit. Starts on the button now. Did have a little flat spot when you accelerated after cruising but I put the original MAF sensor back in and it now seems fine:)

Hi had a call from the garage today to say No2 injector was leaking badly - didn't notice it when I checked but I suppose they have proper equipment to do the test. Replacement on order so have to wait to see if that's cured the problem....

Hi Chaser - yes the pump is giving a good 35psi when cranking, I got the missus to turn the key while I checked

Hello, I've finally reached the end of my tether and the f/l is going into the local garage we use for work. I did find a "pinched" plastic fuel line between the filter & lp pump so replaced this with some new fuel hose. The engine still doesn't want to go properly so away it goes :(. Anyhow...

Sorry almost forgot it's an early 2003 with no fuel tank pump just one in front of the osr wheel then straight to the hp pump in the engine bay. Also checked the ecu plugs when I added the new wiring fix for the hp fuel sensor

Thanks for all the advice, I've been at the lp pump under the osr wheelarch and it's buzzing ok. Also cleaned the sedimenter alongside. Now fitted a pressure gauge in the lp fuel line in the engine bay and it reads 35 psi with ign on and when the engine runs (it will start maf & hp fuel sensor...

Thanks for the advice John, I've got a replacement MAF on order from the local factors so I'll give that a try tomorrow. Whats the pressure likely to be on the rail when the LP pump runs? I was thinking I could fit a gauge in place of the HP sensor on the end of the fuel rail to try it?

Thanks John, I did put TD4 in the title so thought that might be a clue!! I've taken it to the local Landy garage and they got the fault codes for the HP fuel sensor and the MAF sensor. I'd disconnected both once I had the engine running so thought that was the reason for fault codes. Anyhow the...

Seems a common theme about f/l not starting when warm but mine starts when it feels like. Cranks & cranks when hot or cold and (sometimes) eventually fires and runs sweetly. I've read a few threads and removed the fuel pressure sensor (HP) and fuel comes out when ignition on. I've checked the...
