Petrol pump

That I have a problem with my gasoline pump, the car started stopping and then I did not start, (it is the second time it happens to me and the previous time my bomb still had a guarantee, it has 6 months that I bought it and where they bought it they told me that it was the best and therefore the most expensive German brand) take it with the mechanic and when I went in Until I don't start, under the tank to get the pump and Czech all connections and pump in general but it says that everything looks good and possibly the replacement you think? My car is a Cadillac Seville STS 94

Good compa, because you don't have many options. If you hit the tank and the pump starts it is because there is a bad contact or the pump turbine is stuck. Maybe trying the pump off the tank? Or add a land to the pump as well as what it brings? Well, if the pump works correctly, vibration may not allow you to make good land.
