2003 Volkswagen Passat Questions & Answers
I have a 2003 VW Passat W8 and the fuel pump won't turn on. The pump works until it goes in tank. The fuse is good and the relay clicks?????
no enigine told gas or diesel.
i cant see what you are doing
rules :
never run any pump dry, it is fuel lubricated and cooled.
if engine cranks and will not run (not told you)
then measure pump pressure only cranking, cranking matters. PSI cranking only matters, dead engine,.
some cars have key on prime pulse others do not. or based on air temps, yes/no. rules complex. avoid prime pump tests. (savvy?)
some new bosch pumps are 100% silent so noise tests are not good now, use use cranking PSI pressure only if wise. and hate taking a bath in fuel.
11vdc to pump pins cranked. (11vdc is battery resistance drop)
PSI cranked.
that is what matters.
below is battery voltage drop cranked, all 100% good
see the alternator wake-up, IT MUST./
11vdc cranked and 10.5 to pump (ohms laws Vdrop normal)
scopes RULE!
Can I by pass the power steering for a 2003 Volkswagen Passat.
You can't bypass the power steering pump. You would NOT have enough strength to steer.
The only thing you can bypass is the A/C compressor and you do that by removing it and installing a bypass pulley. Not for steering though.
If you want to test the theory find a quiet and gentle hill, turn the engine off and hand brake off and roll. Try and steer. Don't forget you also have no brake assist either, so don't pick up too much speed.

Engine not start Passat 2003
Does the engine not turn when the key is turned? Does it turn and not start? Does it turn and sound like it is trying to start? Need more information
My car wont start but it cranks, what could it be?
Those are known to stretch the timing chains once they get up in miles to the point where the engine goes out of mechanical crankshaft to camshaft timing enough not start. In order to confirm this is the issue a person would have to turn the crankshaft to cyl. 1 top dead center and see if the camshaft timing marks line up where they should. I can elaborate if this is something you'd like to do yourself.
2003 VW Passat Brake Failure
check that the vacuum line is feeding the servo any leaks in the vacuum line will stop the brakes from working abs relays on the pedal pressure to activate abs, if you can hear a hissing sound from the servo then the servo is leaking inside this is if the vacuum line is not damaged, use a pipe or screwdriver on the case and put to your ear and you should hear if its hissing or not.
