First post and injector advice needed

Hello all,
Last week my low pressure fuel pump went so I've fitted a replacement at the same time I got myself a code reader for future issues anyway I thought I'd have a play and the live data is suggesting I've got a faulty injector, I'm thinking of biting the bullet and just replacing all 4 but before I go a spend hundreds on injectors is there anything else I should check first, I should add I have got not symptoms at all, there is no smoke, it's not down on power and no warning lights or codes so I'm a bit lost

Hi Mark.
I presume you have a FL1 TD4 if you have no symptoms suggesting you have injector that is playing up then leave well alone, try some of this below first to see if the readings change, after that do a leak back test on the injectors, but you state all is running well?

Hi arctic,
Sorry I should have said it's a Freelander 1 td4, and yes up to now there are no symptoms at all certainly nothing noticable, seems to run fine only been to 80mph but it pulls strong and there's no smoke at all, I'm doing a leak back test tomorrow, I was wondering in the injector loom could be the issue as I've read a few people having issues with the loom but even then they have symptoms

If is ain't broken, then don't fix it.
Use a double strong dose of Comma Diesel Magic every month, and just drive it until an issue arrives.
