Locate ignition module 1990 BMW 316i E

Are u using the right juice? CHF 11s

Did you check the ECM or ignition module. You need a computer tester for that but they are not that much today. To me it sounds like an ignition module though

Not familiar with the 316i but have had 97 M3 which exhibited similar trait. If the car is manual transmission try to gently pull the steering wheel to each direction while trying the key. If the vehicle is an automatic make sure the shift lever is all the way into the park position. In both cases it could be the safety interlock is causing the problem.
Depending on the mileage of the car - and for a 98 at an average yearly rate of 12K per year - I'm guessing the miles are up there, the ignition switch iteself could need replacing. If you have a good shop manual (Bentley) and posses mechanical abilities it is not too difficult.

Hi , firing order i 1-3-4-2

Not entirely sure what you're trying to ask, so I'll take a shot in the dark. maybe you're asking - "what model years was the BMW 316i produced?"

If so, it was produced 1990-1993 (with a 99hp engine) and from
1994-1998 (with a 101hp engine). More here:

If an engine has timing, compression, the right amount of fuel entering the combustion chamber and an adequate spark it must start and run.

The fact it doesn't start and run means at least one of those requirements is absent. Perhaps fuel is stale, not reaching the combustion chamber or maybe there is too much fuel.

A quick check of the spark and ignition can be made by cranking the engine and using an ether spray into the intake. If the engine briefly runs it can be assumed the ignition is good enough and the problem is fuel related.

Not without disassembling the door. If you are handy you can take apart the window switch and clean it. If not try spraying compressed air into the switch. The switch is likely dirty.

I WOULD LIKE YOU TO CHANGE YOUR PCV VALE FITTED TO YOUR INLET MANIFOLD

the coolant level sensor is at the bottom of the raidiator, ther is an electrical wire going to it so you sould find it easily.
