Driving around the city, when switching gears stalled, started up immediately. Then when climbing uphill, a sharp loss of power. The motor does not pull at all, I had to gas up to 4-5 thousand and letting the clutch go up the mountain. There is stalled.

Now only wind up completely cold. It will work 40 seconds and a minute and stalls. After that, it will not start. During this time, the engine is almost not heated. Starts only when stand 3-4 hours no less. When the engine starts, the sound of the engine and the response to the gas pedal are normal. Then stalls abruptly and will not start.

There were no errors. After many attempts to start, P0410 appeared. Erased Does not appear.

I measured the compression on a warm compressometer, when it does not start up. In the first section 6.5 in the second 4-4.5 with a starter speed of about 200-220.

What could be? The problem is only in compression? Prior to this hot start, though 2 kW starter.
Maybe the problem with fuel supply? The gas pump is buzzing, the pressure has not yet measured. By the way, what should be a tee?

It is confusing that after a minute of work, the machine should stand for about 3-4 hours, then it can start again. It does not heat up much in a minute. Usually machines that do not start up hot due to compression cool down faster. And in a minute it does not heat up.

What could be problematic?

I apologize for my bad english)

What is the condition of the ignition coils?

Those compression values are failing, especially the 4.5. What did you measure with though? A regular compression tester doesnt give accurate resilts.

drb222

Coils probably normal. Unfortunately, it is possible to measure the compression only with an ordinary pressure gauge. The fact that the engine runs less than a minute. during this time it works normally in the whole rev range. then the engine can not start 3-4 hours. I know that cars with bad komcessiyu start and go. then the hot ones do not start but cool down in 30 minutes - an hour. Maybe my problemma in the fuel pump?

"Probably normal" sounds like coils of unknown age that need to be replaced. Stock ones are not reliable past 50,000km. That may not be the complete solution, but definite something to check while you're working on the car. Bad coils will kill your (future) engine.

It could be the fuel pump, potentially also the clutch safety switch.

The bigger question in my mind is if the engine is really that low on compression, you are going to need a replacement. Do you still want to keep the car if that's the case? If so we can keep troubleshooting, but if not there is no point in doing that.

Another thing: how is your catalytic converter? Take it down and have a look. If its completely blocked your car isnt able to push out exhaust and chokes.

drb222

I understand that the compression is low and I am going to replace or repair the engine in the near future.

But it seems that the current reason is something else. Why does the engine work normally just a minute? doesn't he have time to heat up so fast? Why does it have to cool for 3-4 hours? He really cools faster?

What is a "clutch safety switch"?
My catalyst has long been removed.

Yeah I don't think its a question of heat, sounds more like pressure somewhere. I would check fuel pressure next.

Revealed that there is no spark on one candle. Checked as follows. Disconnected the wire from the candle, inserted the usual candle, the mass of the candle connected to the minus of the battery. Spun the starter. So there must be a spark?

The fact is that after standing overnight, the car started up properly, after a minute it stalled.

All four coils could burn out immediately? why standing up?

Nearly every time I've seen or experienced this issue, the cause is low compression. You may be chasing your tail until you do a proper compression test on the engine when its at normal operating temp and with a rotary compression tester.

drb222

But after all the spark in candles should be at any compression? Why is it not from one coil? Is it a separate coil or one common? could all four burn at the same time?

Which one was it that didn't fire? Leading or trailing spark position?

Coils fail, that's life with these cars. Very common/inevitable. Replace all 4 because if one is dead the rest arent far behind.
Dead coils + low compression gives you problems like you have.

You can do a test: if the failing coil is a leading, swap it with one of the working trailing. See if the car works better.

If it does you still need to replace all 4 coils but at least you've confirmed the cause of the problem.

Tu peux aller en francais aussi.

drb222

I already wrote that not a single coil is working. Could they, all four fail at the same time?
For some reason, the control signal may not come to the coils?

Its not super clear what you wrote

If you're not getting any spark at all, perhaps the eccentric shaft sensor is not working well or is damaged. You can google what it is and where to find it. Quick test: get an OBD reader and watch the rpm signal while you crank after it stalls out. If you get no rpm signal, its not reading the ESS.

Or, as mentioned earlier, clutch safety switch. You can google that too.

Compression of 4... That's a major problem right there. And I assume did the test cold, so the hot numbers are even worse.

That could really just be it IMO. You might have shattered a seal or something.

Swap the coils as mentioned above and see if the no spark condition follows the coil being swapped. If it does, you have a bad coil. A failing eccentric shaft position sensor can cause a no spark condition as well as a no fuel condition just so you're aware. If you are stuck on the ignition being the culprit, then do a coil swap test. I however still believe that low compression is the cause, but I am willing to help you diagnose the no spark condition if you want to start there.

If it's an ignition issue, then why does the car die after a minute or so of running?

The car runs the richest when cold so if it can start the car up when cold, it shouldn't have trouble stay running. I don't think ignition would just randomly quit after a minute.

I am thinking maybe fuel pump? It's just so close to dead that it will only supply adequate fuel for a minute and then it overheats and dies. A bit of a random guess, but you can always confirm this with a fuel pressure gauge.
