My car has been stalling when it get's hot, and then it is very difficult to start . This happened while I waited at the Mexican border with folks that did not have my front of the line pass so I was in line for two hours. The car decided to stall and was not able to turn on, The folks with me pushed the car to the US guard then the car was able to start. Everyone thought it was vapor lock . I thought so too , even though my car is fuel injected . This happened twice during other times . Two days ago , my car did not want to start at a Carl's JR parking lot , I attributed it to hot temps 90 deg F outside. I disconnected one of my injector hoses and let the fuel flow to a can , put it back together again, the car started again right away. Hmmm , vapor lock again because of a hot day ? Yesterday, the car stalled at a red light and would not start so I had to push the car to the side . I removed the injector hose again and nothing flowed out when I turned the key. The pump was not turning so I hot wired the relay to keep the pump on all of the time + power on the pump all of the time and GND - on the pump all of the time too. The pump stil did not turn. I checked power to the pump and it was there ,12 V, I then banged the pump with a wrench and the pump started . I bought this pump two years ago , it was a new Bosch unit that had exactly the same problem. To get it going , I must bang on the pump when the car stalls , for some reason this is the same failure as my old pump, I think Bosch quality is slipping , I think I still have the receipt so I can get a free new one. The pump stops turning after car has been run for a long while and the battery/regulator voltage is not at it's highest after full charge , usually happens after engine is turned off or it is at idle. When cold and during higher voltages or during battery charge , the pump overcomes it's faulty limitations. Dc motor with internal faults tend to act like this , usually burned wires or dirty brushes, these are sealed pump motors. I did not find any foreign matter in the pump I replaced two years ago , I will check and see if anything in the impeller is getting it stuck in this one , I doubt it , I vote for bunt motor or worn brushes.
