Im at a loss. My 5.3 has fired right up every time I have tried...until after doing an oil change today and getting ready to tow it to the driveline shop. Fuel pump is working and I can smell gas while it cranks but wont fire. Has 1 trouble code p1518 which has to do with the TAC module...i have checked all of my wiring, checked my fuses. I am at a complete loss. On the bright side I tried to start it before calling the tow truck, would have sucked to pick it up from the driveline shop for it to not start and need towed again.
