ok 2001 gt 5spd. vortech supercharger installed 04 i think. car sat for 2 years. i just bought car. put 400 miles on car. last week stabbed secongd gear and light comes on. go to mech he says fuel rail sensor code. he clears it but cant test it with his scanner causew car is chipped. car is fine for a week then does same thing. mech is talking to someone who works on lightnings and wil;l report back. car has full lenghth headers, exhaust, shifter, vortech, chip. mech says it might need a boost a pump? mech says it might need to be tuned from sitting? car was supposedly prof dynoed when vortech installed.

Fuel pump going bad? Definitely take it to get dynoed just to be safe. Tuner would be able to tell alot.

well if your fuel pump is bad i would not max it out on a dyno then. replace the pump to be safe then dyno. There are other ways to tell a bad fuel pump than to hold the pedalto the floor on a dyno..
