cdti non starting issue
 

need some expertise here...

a 75 diesel was giving symptoms of ubp failure...

sometimes in driving it went down, started it few minutes after and it fired up...

sometimes first thing in the morning did not fire up at all, gave it a few moments and it started...

yesterday decided to stop completely, so replace the ubp, the itp seems to work ok, at least i hear whirring from the fuel filler. fuel is almost topped up...

after replace the ubp it fire up ok, but then after stoping it didn t start no more til today i cant seem to fire up...

can hear it crancking but it does not fire up...

checked the plug to the rail, checked the plenum and is boné dry...

can someone help me here???

thanks.

please a big bump here....

please.......... bump

Have you tried unpluging the fuel pipe from the filter and see what the flow is like from your new UBP,

Also could be the cam sensor as others had pointed out to my enquiry

Stubs

What year is the car?

hello, yes i have cleaned the plug of it...

i did not remove from the place... but shouldn t the cam sensor symptoms happen only at warm starts???

the car is from the year 2000...

yes, checked the pipe that plugs the fuel filter and the flow is good...

the problem comes after i think...

Have you changed the fuel filter?

Is there any difference on the instrument console (more or fewer warning lights when key in in position just before starting) as between when it will start up and when it will not? If so, post photos.
