Injector fuse gets destroyed after 2 sec of Engine running. Injectors are measured and seem to be OK.
SOURCE: I own a 1999 VW polo. The oil pressure warning light illuminates
hi i had a similar problem with a seat leon {vw golf} it turned out to be a defective oil pressure switch only in this case it was knocking the speedo out try disconecting it and take it for a drive, these are overly complicated cars!
SOURCE: Why is not there a VW Polo 6N listed?
if warning light control not working change the altenator
SOURCE: engine revs on its own! vw polo
There are many number of reasons for this problem...but a VERY common
one is a faulty thermo sensor which controls air / fuel ratio.

I'd suggest joining a VW forum like VWVortex.com
and find out more about your vehicle. There are plenty of websites that cater to your VW.
TIP: Try unplugging the injectors one at a time and cranking the engine to see if it will start. If the engine starts when a particular injector has been unplugged, that's the shorted injector that needs to be replaced.
TIP: You can also measure the resistance of each injector with an ohmmeter. Unplug the injector and measure the resistance between the two terminals. If resistance is outside specifications (high or low), replace the injector.Noid Light kitProfessional technicians use a tool called a NOID light to check injector pulses. The tool detects digital signals in a circuit and flashes an LED light. No flashes from the injector circuit when cranking the engine would tell you the PCM is not pulsing the injectors. On newer gasoline direct injection (GDI) systems, however, a NOID light is no help.
If the injectors appear to be working, but the engine will not start, the engine may be flooded. You may have to remove the spark plugs to let them dry. Wait awhile then try it again.
Note; You can also try holding the gas pedal all the way down when cranking. This will put the PCM into the "Clear Flood" mode when cranking the engine.PLEASE SHARE ENGINE PORTAL NEWS
