Engine Performance Problems Due to Crankshaft Position ...

Clean the throttle body and maf or map sensor.

When this happens have a can of spray starting fluid on hand, spray it into the engine air intake, if the engine starts you may have a failing electric fuel pump

Yup ignition switch is done

Your best bet, is to have it taken to a repair shop.

You don't know where to look or what to do,if was
the starter, what then ?

The Check Engine Light does not have to come on for someone to find out what is wrong. A shop may have to have the car for a few days so they can run some tests on your fuel and ignition systems. They will most likely have to drive the car/run the engine to duplicate the symptom so they can catch it while it is malfunctioning. Intermittent problems can be very elusive, but they can be diagnosed with a little patience. The level of your fuel gauge most likely has nothing to do with your starting problem.

You've had an experienced AA repair man look at your car and thoroughly check the obvious faults. May I ask why you doubt what he's told you? It's impossible to say he's wrong without also having a chance to examine the car.

It's definitely possible that he's correct though.

Just change the sensor: it costs peanuts, takes minutes and is easy to do, but you may need to drain the coolant down first (catch it in a clean bowl and re-use it if it's not all black or rusty as it's not cheap). When refilling the coolant set the heater control to hot to avoid air locks.

It's hard to know whether or not this is a fuel issue or a spark issue. Here is where I'd start:

Have a mechanic check your fuel pressure to make sure you're getting fuel. An intermittent starting issue could point to a clogged fuel filter. This would be more likely than the pump.

With the age of the car, a faulty main relay could also be the culprit. They are notoriously bad on Acuras of that age. The solder joints break and they will work one minute and not allow the car to start the next. (starter will turn the engine over but not "catch")

If this problem happens more often when the weather is hot or cold, it points toward the main relay. Good luck.

To be honest,sell it. You're getting in to more electronic issues than the car is worth.I can tell you the z1 circuit is shot,that's the main engine ground under the battery tray. That's just the begining of the electrical issues.

My car is a 1993 190e 2.6
For Zero dollars you should check the Over Voltage Protection fuse before spending any more money. When burnt out this thing can really cause some strange things to happen example: ABS light on, low rough idle speed, difficult or no starting without a "jump". My battery was new, the starter and alternator were fine. I was Lucky enough to know an expert he took one look at it swaped that fuse and all was good. Immediatly good idle, ABS light went out, Car starts great.
Check it first!
By the way you can change the brushes on your starter with out even removing it from the car.
