Hi ive got a 1997 polo sometimes it starts sometimes it won't when it does start it cuts out straight away any ideas Thanks

SOURCE: VW Polo Classic 1997 IDLE Problems

Hello, VW polos 1.0, 1.4. 1.6, suffer from carbon bulid up in the throttle bodys causing bad idling, esp the Bosch Mono-Motronic (Throttle Body Injection systems), a good clean with carb cleaner should repair the problem, also engine temp sensor replacement and idle speed control valve replacement can help idle problems.

try disconecting the coolant temp sensor and then try, it may be faulty, also check the hall sender unit in the distributor, if it has one, the centre pin should be the signal wire if no pulse is present the sensor is faulty

This sounds like a problem in the fuel shut off circuit. When you turn the key on, it energizes the fuel shut off solenoid on the injection pump. When you turn off the key, power is removed and the pump is moved by spring to the fuel off position. Check for power at this terminal when you are having a problem, ( with the key on) If no power then I would check the wiring and connectors from this connection to the Ignition key. I believe it is wired direct. That can be checked at http://www.alldata.com/products/index.jsp

subscribe3 and get a wiring schematic for the car and see if it is wired direct to the ign switch of from a relay, I am sure it is a connection problem if you have no power.

A 1.7 diesel even if turboed, is dead slow in any vehicle let alone a van. Enjoy the fuel economy

good luck

I had a similar problem with my 1986 300e , which got progressively worse until the car was no longer driveable, I changed out the fuel pump relay and the problem went away.

8 seconds and stall,..

Sounds like you're starting fine and there's no apparent problem with the engines electrical impulses in regards to wires, plugs, coil etc,..

Which it sounds like you're running off residual fuel but continuous fuel supply is being disrupted.

I'm all but certain if you pull a SP it'll have unburned fuel on it. Check your fuel pump, filter, pressure regulator and injectors

From those symptoms the pump could be faulty, filter clogged and only feeding seepage, the regulator could be flooding it out ot the injectors aren't opening { clogged }

What do you get when you try to press the accelerator when it's running or have you not tried that?
