I had a problem with my 08 3600 3.0L going into limp mode. Shut it down, and restart, worked ok till the next time. It gradually got worse. Found out it was the EGR valve. It was dirty. Took it out, cleaned it with carb cleaner and nylon brush, put it back in and problem solved.

Re: fuel pump issues on sprinter 2007
Doesnt sound like a fuel problem....check the charge air hose on the lower drivers side at the metal ring....they tear loose there and check the tubes going to the turbo....the green o ring has been known to go bad

There is no emergency shutoff for the fuel pump. It is controlled from the ECM. There is a fuel pump relay in the relay/fuse box under the hood. But if you have power to the pump, it is probably ok. Having had a 1999 Dakota I had a situation where I was having intermittent shutdowns when driving that became more and more frequent. Sometimes I could restart immediately, other times I had to wait from 10-30 minutes before I could get a restart. I assumed a faulty fuel pump and replaced it only to find that it did not solve my problem. I researched the issue and found that the Dakotas and Durangos have a tendency to have faulty crankshaft position sensors. It will mimic a fuel pump issue since when the ECM loses sensor input, it shuts off the fuel pump. Test the pump this way - in a quiet setting, turn the key to the ON position, but do not crank the engine. With the drivers door open listen for a 2-3 second humming sound from the rear of the truck. This is the fuel pump priming the system to get fuel rail pressure. What then happens is once you start cranking and the engine fires, the ECM turns the pump on full-time. If the crank sensor is bad, the ECM cannot see that the engine is turning over and does not generate spark or fuel injector pulses, so even the fuel pump prime works, if it worked won't start the engine. At least if you hear the prime, you'll know the pump is functioning.
P0087 is a low fuel rail pressure code. One of 2 likely causes. the quick diagnosis is to turn the key into the "on" position and listen for the fuel pump hum. If there is a hum, but the van doesn't start, I would then check the fuel filter. in between 80k and 100k miles, some of the sprinters run into a fuel filter issue where the fuel is too restricted to flow to the injectors properly. If you don't get enough fuel through the injectors, the engine will rotate, but not get enough vapor concentration to start.
Remove the battery ground (negative) cable from the battery. Remove the throttle body air inlet duct. Set the park brake. Shift the transaxle into Neutral. Remove the engine mount strut bolts. Swing the engine mount struts aside. Install tie strap between the engine and the radiator support. Pull on the engine in order to rotate the engine forward. Tighten the strap. Remove the generator B+ terminal nut. Remove the generator B+ lead. Remove the generator electrical connector. Remove the drive belt from the generator. Remove the generator front bolt. Remove the generator rear bolts. Remove the generator from the generator bracket and position the generator above the drive axle. Remove the drive belt tensioner. Remove the generator bracket. Remove the power steering pipes from the power steering pipe retainer. Remove the fuel pressure test port (schrader valve) cap from the fuel injector rail. Remove the power steering pump and reposition the power steering pump in front of the timing chain cover in order to provide access for the generator.
IMPORTANT: Do not disconnect the power steering pipes from the power steering pump.
Remove electrical harness from retainer on right fender well and position aside. Remove the generator from the vehicle. Reverse procedure to install
Your oil light is not a symptom. It's flickering because as the engine dies, the oil pressure is dropping. The engine's power pumps the oil, so this is pretty normal. The engine slows down, the pump will also, and there will be less pressure.
As far as what to try next, I would assume that a 1990 has throttle body fuel injection? (The kind that looks like a big 2 barrel carb) If this is the case, you should look to see if fuel is pooling on the butterflies at idle. If it is, then you have an injector stuck in the open position, allowing unregulated fuel to flow into your engine. If your engine ises direct injection, where there would be 8, or 9 injectors (9th would be the cold start injector), one or more of them may be stuck in the open position, but I would check the cold start injector first.
I'm sorry that I am not really familiar with your exact model. We don't have holden here in the states.
place key in ignition. turn to acc ,make sure radio is off listen for small hum it last about 15 to30 sec if you hear hum pump good . no hum check fuse if good more than likey bad pump. check if it has a glow plug
under the left side of the dash is the fuses and relays....check fuse 16 and 6 for power....the asd relay is also located here....if it has power and no ground possible wiring problem or enine control module
