Penske teams suffer fuel injection problems

Secret or not, #2-Brad Keselowski and the rest of his team have learned their lesson from last year's comments about the electronic fuel injection system and want no more fines from NASCAR. So the outspoken driver bit his proverbial tongue on Twitter Sunday afternoon after leaving Las Vegas Motor Speedway very disappointed with his 32nd-place finish. For the second consecutive week, Keselowski had some fuel pickup issues, and this time it hurt him much worse than it did in a fifth-place run at Phoenix. After Landon Cassill blew his engine on Lap 246, Keselowski couldn't get going on the restart and was well off the pace as cars passed him on both sides. After the race, Keselowski said there was still fuel in the gas tank, meaning it was an issue with the fuel system. Keselowski, however, wasn't the only Penske driver affected. AJ Allmendinger in the #22 had his troubles much earlier, but they continued throughout en route to a 37th-place finish. According to the team's Twitter feed, the fuel pressure issue first showed up on Lap 149. The team spent several laps in the garage about 40 laps later, first trying to replace one part, and then later swapping out the whole electronic fuel injection system. NASCAR.com
