I'm a single dad working a full time job and dont have have alot of time to fiddle with stuff, so any help is hugely appreciated
04 jetta BEW tdi manual
Short list.
Fuel pump went out and replaced it and the car would run but cranks for a while if it sits over night, drove it for a week like this then it stopped running but will start if I use wd-40 and runs grate but need to use wd-40 if it sits overnight.
Long version
So one morning I go out to leave for work and the jetta wont start.
I test the fuel pump and it's getting power but not running and I removed the feed line and yupp, nothing.
So order a new pump from IDparts and install it in the assembly and put it back in the tank and cranked it for awhile till the air passes through and it ran grate and the next morning it cranked for a little bit until it fired up but would fire right up unless it sat for more then 8 hours. (Like the fuel line drains)
But when I got home I noticed the fans were running even after I turned the key off and it's never done that before.
And they run for 5mins if the engine is cold or hot.
They operate normally when the key is on and the engine is running but will turn on every time when the engine is off and key is off.
So drove it for a few week like this then tried to start it one cold morning and it ran rough ( bleeding out air ) then it died and wouldn't start.
Would try and start it a few days through the week and confirmed it was pumping fuel but nothing.
So yesterday I sprayed wd-40 in the intake and it started and stays running and runs grate, let it sit overnight and it wouldn't start untill I used the wd-40 and runs grate and drove it to work (108 mile round trip) with no issues.
It's like the injectors are not firing while its cranking.
Before all this happened, I was having cruise control issues, the speed would bleed off until I tapped the throttle and it would go back up but then it just stopped working.
The tandem/vacume pump on the motor does weap diesel but has for years without showing any mechanical problems.
Any ideas or anything I can test?
