Peugeot 307 petrol too late start

All my greetings. My 2002 model 307 1.6 xr car works at 3 marches in the mornings, not only in the mornings, but 2 or 3 hours, it's still the same. It only does this in gasoline. When I want to run a LPG, if I want it to start in 2 seconds, let it wait 30 hours without working. It was the same although certain repairs (gas injection torque change, gasoline pump replacement, gasoline injector cleaning, throat valve cleaning, ignition system replacement) were made. I'm waiting for your help.

I checked the sockets of the crank and eccentric sensors. Gas pump pressure was measured, sir.

They said the gas pump pressure was low, I got zero, the original pressure was restored, it works again the same night.

Sir, there is LPG in the vehicle and it may be due to the LPG ragulator. As the seals inside wear out over time, it may cause gas to escape in the manifold and it may cause it to run late as it is mixed with two fuels in the first start in the morning. turn off lpg. Turn off the LPG valve on the tank and observe it.

They said it was intact in the regulator and I had it checked.

Nowadays, many people around me are also a growing complaint. After the pandemic, alcohol started not to be added to gasoline, so I did not understand if the injectors were damaged. The same problem started with me. Problems occur when it stops working for a long time. It takes start and stops without 1 second. He takes the 5th or 6th March like this. When you run it directly, it gets it immediately. I turned off the LPG from the valve and tried it the next day, I thought it was all right. But a day later I tried the same thing again, it worked late. There are three possibilities in this situation. Injector is peeing, car suffocates on first run. 2. Gas pump does not provide sufficient pressure when cold. 3. There's a problem with the gasoline recycling valve. It sounds like an injector to me. Because the car runs but it stops by drowning.

My teacher does not stop, does not work at all, the same as if there is no gas. But he's been running for 2 seconds on the second march

Then it is necessary to focus on the gas pump and recycling valve.

The gas pump was original I got zero, the room has changed
