Customer Question

Hi there Mike,
I have a year 2000 vw Lupo 1.4 16v which won't start, it cranks over but no spark at the plugs, I've replaced the battery spark plugs and ignition coil but still no spark, I then tested the power plug to the ignition coil, with a volt tester but the reading were nil or very low when cranking over, any help would be greatly appreciated

Have you checked the crank sensor yet ???

Customer: replied 1 year ago.
No, I found the crank sensor under the front engine cover, I will order one and replace it during the week, is there also a tdc sensor on the car or are the tdc sensor and the crank sensor one of the same thing? Sorry, I'm somewhat a novice at this game 😥
Expert:  vwtech0405 replied 1 year ago.

There a cam sensor also but before you order anything you are positive you have fuel pressure and no or weak spark ??

Customer: replied 1 year ago.
defiently fuel pressure and no spark at the plug or the ignition coil

Where would I locate the tdc sensor on the lupo, as I've looked around the top of the bell housing but couldn't locate it, the lupo engine code starts with Aua. Many thanks

Do you mean the cam sensor ?

Customer: replied 1 year ago.
Sorry, yes the can sensor then
Expert:  vwtech0405 replied 1 year ago.

The cam sensor is located on the top portion of the engine usually located on the valve cover top right or behind the upper cam sprocket
