Question about 1995 Volkswagen Polo 1.4
The locks are tied into the alarm control unit. The control unit has a
starter lock out. If the alarm system did not see a door open using a
key, it does not deactivate the starter lock out.
Normally if you have a bad door contact switch you can open another door or trunk to test this theory out. Since you can not do this, we will need to take a few steps. You need to locate the alarm control unit, it is a small black box located just to the left side of the steering colum. You will see a large conector of wires that go to it. Locate the two large red wires, one will be red and one will be red with a black stripe.
Probe both wires, and while turning the key to the crank position you should have power going through both of these wires. If not let me know. If you do have power going through both of the wires, then the problem is not the alarm unit.
Hope this helps.

SOURCE: VW Polo doesnt start
when you turn the ignition switch on, the gas pump relay should turn on and go off to pressurize the system. You can keep the car in neutral/park, get down as low as you can to the driver's floor board and reach up and turn the ignition switch to on [but not to the point that you actually allow the engine to turn over]. Repeat this step until you hear the relay and can actually feel the little black (box) that is actually performing an electromechanical switching.
Check here first----> , it is usually on a diagram within or near your fuse panel.
It is a start. Secondly, I'd check for any play/movement on your negative/positive terminals of your battery and starter motor. Should these be snug, loosen them and clean the terminals on your battery AND starter. This may be "stupid" and "obvious" to most but they don't do it and that is usually the main cause... even if it "appears good".

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

Several things to attack here... use a gauge to check fuel pressure at the injector manifold... should be 80 psi i believe... also check the fuel pump relay it may not be working right in the "start" position... (yes it's actually two relays in one... one for "start" and one for "run"... test this by attaching a light or meter at the pump terminals (under the car, right rear) if it doesn't light right up (or show battery voltage) when key is turned the problem is definitely electrical... if pressure is low, first replace the filters, if still low then suspect the pump(s). oh did I mention there are two pumps? One is called the transfer pump (in the tank) the other is the high pressure pump. Rule out the high pressure pump before suspecting the transfer pump.
Hope this helps...;-)

easy to change its on top of the injector pump ,but you may have a antitheft shroud around it which means removing the pump from the engine to get get the shroud off
