Hello, sorry for my absence but I had many things to do, the car always starts on petrol then accelerating after a certain number of engine revolutions it switches to gas. The problem is that he doesn't always do it, but after a short stop at the restart with petrol around 1500 rpm there is a weakness. The problem occurs only with petrol also because it always starts on petrol

Good morning I solved, it was the petrol pump as you said Ludel in your three options, I bought the petrol pressure gauge and while I was waiting for the package I heard the pump make a noise like continuous telegraphy, so I decided to disassemble the tank and change it. I replaced the pump with the Airtex pressure 1.20 and the machine went immediately well. There was still a problem I was hoping it would disappear by replacing the fuel pump, at departures I sometimes lack the power at 1500 rpm it could be connected because the jeep when I turned it off was on LPG and the start is on petrol. I hope google gives me a good translation

Okay Ludel, I'll let you know

I did the test of the minute and a liter of petrol because I do not have the manometer that measures the pressure of the petrol the result was 1 minute and about 100 cc of petrol as you can see from the images the blue sign is a liter and that little petrol it is the result of 1 minute, I shorted the pump relay as you said or the pump or some block, tomorrow I take off the tank and see what I find and then report here. However, the first symptoms that I did not give importance to were already a month ago, when it restarts from short stops the engine went to fits and starts, then the defect increased more and more, until the day before yesterday it did not start anymore. Your directions were right

Thanks Ludel for answering me, do you think I can skip the fuel pressure test by doing the test as I have read in your other conversations that in one minute the fuel pump should fill a 1 liter container

Hello, I have a jeep wrangler 2500 from 1988 with a gas system, it started tugging when I made stops and then I started again, the shorter the stop and the more it tugged, this only happens with gasoline gas has no problem, now yes it is aggravated and it is difficult to start it and as soon as it starts it turns off, if I insist I can even go. At the moment I have changed the mono injector and fuel filter, the only test I have done is to turn the key and see if the fuel pump was pushing the fuel, as I turn the key with the engine off the pump squirts the petrol and then stops. I know there are good mechanics here and forgive my writing, I use google translator
