Where is opel astra`s oil sensor connected

Test fuel pressure if below spec.get new pump

Identical cold start issue on my Astra IE 1996 F series after the engine got rebored - after months the new oil pump was found to be faulty & clogged-up & replaced by the spares supplier - the car then ran perfectly after this. I was told the blockage created a backpressure & the computer was stopped it starting.

16 years later - 10 yrs after the last service covering just 8600km (last 2 yrs car hardly started) has identical cold issues again. It can be driven around & wont take long cold start in our warm coastal winters. The good mechanic seems to be giving up trying to fix my old car but refuses to believe its a low oil pressure issue saying that just makes the oil warning symbol light up & doesn't affect a car starting. I want to check if the engine warning light works on starting showing the low oil pressure sensor is working. But his now busy searching for a Astra specific temperature sensor.

the oil filler and level indicator are usually at the same point which is usually on the side of the gearbox. removethe plug, fill the gear box with the correct oil until the oil starts to pour back out of the plug hole. then replace the plug. (basically)

locate the crank sensor there should be two screws and a electric plug pretty simple if u can locate the sensor

Check for water in the oil or have the cooling system pressure tested

There are sensors that detect if the engine is running after it starts. Oil pressure sensor is a major one. I don't know exactly since I don't have an electrical diagram to see all the possible sensors.

the sensors probably sensed the smoke in the exhaust and threw a code. Keep driving it and it should go out once all the oil burns off.

Whoa! I'd be looking for a new wiring harness and an independent mechanic to install it.
