E30 (1982 - 1993)
God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

Mein Auto: 1984 BMW 318i
318i m10 shuts off after starting and when you give it gas

I have a 84 bmw 318i with a m10. i have replaced the battery, MAF sensor, idle air control valve, distributor, but i still have the same problems. It will start idle for a moment then shut off. if you give it any gas it will flood itself out spit and sputter. also when you turn it off and pull the key out the car will stay running for about 10 seconds then shut off. I REALLY NEED HELP! if anyone one can give me answers i really need them. the bmw is in the shop right now but the mechanic is also struggling. he is checking the fuel lines out monday. Thanks everyone.

thats VERY strange that it keeps running if you car is a fuel injected car. not uncommon for carby engines in poor tune to do that, but pretty much impossible for efi engines.

your car does not have a MAF sensor.

is your car EFI or carby?

If EFI, consider replacing the blue coolant temp sensor.
Also check all hoses associated with the intake sensor for cracks which self seal when the engine is off or at idle, but are pulled open when the engine torque makes the engine roll on its mounts with throttle application.

Haven't had to work on an M10 in about 20 years, so I'm generalizing from my M42 experience. In the near term, I'd be looking at the fuel system (filter, pump, pressure).

Over the last two years, I've been able to clean up a lot under the hood. As you get the funds and time, consider doing the following in addition to what you've already wrote about

Attend to all air leaks (vacuum hoses, intake manifold gasket).
Replace any old coolant hoses.
New fuel injection-rated hoses and clamps if required.
Test the throttle position switch, replace if needed.
Check alternator output, and replace the voltage regulator/brush assembly.

I just swapped in a used fuel pump, and that corrected rather severe drivability problems. Adding in a better used ICV and refurbished AFM, and my 216K+ M42 is back to its customary reliable self.

I have checked vaccum hoses. and fuel pressure is 48 psi. both fuel pumps are good. its a fuel injected bmw. no carb. injectors are shooting fuel. thanks everyone for the info. but its everything we have already done to the car. but its still going about with the same problems.

Stupid question but after replacing the distributor do you have the plug leads in the correct sockets ie. is the firing order correct?
