My problem started a month ago (ofcourse when i became unemployed...) I would power up my truck and it would turn the vehicle power on but the engine would turn right back off... second try always worked. I did not and still dont have the money to fix it, my mother helped me out and i ended up getting a full tune up which did not fix anything. not my fault she is the one that took it in.... anywho problem continued, when i picked it up i almost cried since she spent about $600 and it was not even for MY problem at the time. yes i needed a tune up but there was a more important issue that NOW just got worse. I believe it might have something to do with this first problem, now my ABS light is on... my truck feels like there is something wrong... (frustrating :( since im barelly getting back on my feet) and the Transaction light is also on. this sounds like what my old car had and it was a $3,000 issue........... i have the worst luck with that ABS module am I doing something wrong?!?!?!?!?
Abs light and transaction turned on, started with a failed attempt to run engine on 2000 Chevrolet Tahoe

The vehicle will need to be scanned at a shop to find the cause of the ABS lamp. When the computer identifies a fault in the system, it illuminates the lamp to alert the driver. The traction control will be disabled if there is a problem with the ABS system. That's why both lamps are lit. The brakes will still function, but will lose the anti lock ability. As for the running problem, it sounds like a fuel pump issue. The fuel pump has a check valve inside of it to maintain at least some pressuer in it for a while after shutdown. If the lines were to empty back into the fuel tank, the vehicle may exhibit symptoms that you have. This is only an educated guess, and there other items that may cause this.
