Polo Coupe 1043,1992, Will not start, can be bumped started, sometimes!!, theres a strange clicking noise from under the air box, when the ignition is on and sometimes the oil pressure light comes on when the car gets upto temperature, then I lose all power and then the engine cuts out. I've recently changed the dizzy cap, rotor arm and battery, all the leads are new ish along with the spark plugs. The previous owner has changed the head and done all that, leaving much of the engine loom unlagged and bare. Could this cause a problem on some of the electrical systems?

I just posted my experience in another place on this site but on my 1992 PA the accessories relay stuck closed. This relay is the one that allows you to listen to the radio etc and keep things on until you open the door then all shuts off. When it is stuck closed accessories keep running until your battery drains dead. The relay was replaced and all worked great.

It's very possible a coincidence and that the flashing oil light is the oil pressure switch. I'd check it out immediately to make sure there's sufficient oil flowing through the engine. Merely jump starting the car shouldn't have knocked anything loose so to be on the safe side, assume there's an oil pressure issue. You were right to not use the car in the interim.

Is the check engine light on ?

SOURCE: Buick Century 2003 service engine soon light

My service engine light was caused by a cloged passage from my EGR valve. Mine is a 3.1 with fuel injection 2003. All I needed to do was pull the two bolts over the intake plenum and remove the vacuum connection to the PCV valve. Then clean out the EGR port just below the vacuum connection in the throttle port. I would remove the rubber intake to vacuum it out. The carbon was like rock in there. Service engine light cleared on its own.
