ford ranger broken down

Hi Bob, yes we replaced the fuel filter cleaned the tank it had some dirt, but totally cleaned out, the fuel pressure is way to high , it did revert back to normal pressure but once we turned it over it went high sky again!! this in turn wont let the injectors open, we think !!

My understanding is that in most common rail diesels the rail pressure is >1800bar or 27000psi or higher. I'm guessing that there is not too much wrong with your rail pressure at all.

hi dust devil
how could russells fuel pressure be too low when he clearly said it scanned at-

38,982 psi

that sounds too high if anything
in respect dd i would suggest you have mis-read the figures
russell has quoted

Your dead right about the 38,982psi and he did "clearly say it scanned at 38,982psi" and I am even more sure that I did not contradict those figures in any way what so ever.

I am even more sure that Russell said he wished to get the aforementioned pressure down to 3,000psi:

Just to get some clarity in this tread I will copy and paste Russells exact words:

"I have just replaced my diesel injection pump and still won't start ! I have put it on the scan tool and tells me that it has 38982 psi it should read around (3000) at the fuel rail wether the sensor is plugged in or not"

Now I read that as Russell stating he wishes to reduce the current pressure of 38982psi down to 3000psi.

I was merely attempting to point out to Russell that later model vehicles like his CRD run a RAIL pressure at around 27,000psi, and therefore his attempt to lower his CRD to 3,000psi would be aiming for to low a pressure.

Then again I could have "mis-read" Russell's figures as you say and if that is so, I apologize most humbly to Russell for misreading his figures and promise never to do so again.

hi russell
there is one more thing you could try
turn off the key and remove from the ignition and close all doors with interior lights etc
then make sure there are no auxillary items drawing power off the battery then read the manual as per
disconnecting the battery terminals as some vehicles with ecu's do have specific precedures for this

and although you might say what good would that do you may be pleasantly surprised at the results then after cleaning the terminals

reconnect them but check the manual for correct procedure as above vehicles have specifics in doing this

the ecu will reboot and you may find the problem you previously had is gone these computors are strange creatures
its worth a try and only take a few minutes
i know of had a couple of issues one personelly where doing this has eradicated a so called bug
it would be better to try this than use the petrol and matches
