Got a 2001 Saleen supercharged. Had it for 8 years and it came from Saleen. Low mileage with 18k. Living in Texas and had the battery on a tender with some cold weather. Took it out today and ran fine then started to idle rough and shut down. Finally got it started but it is not running smooth at all. Could it be a water/gas problem ?

 

Here is an information update. After changing out the fuel filter and fuel pump relay we found that the fuel pump was clogged up at the inside strainer/filter. This was located on the fuel pump assembly. Car runs perfect now with normal boost readings at 10-12 pounds. Will now monitor and add a fuel additive going forward!.............

 

Problem solved....Glad I could be of assistance...LOL
