Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓Car cranks but doesn't start (fuel pulse killed by VATS)
- ✓Engine starts then dies after 1-2 seconds
- ✓Resistor pellet in key worn out or broken
- ✓VATS wires under steering column broken / corroded
- ✓VATS resistor module failed (under dash)
- ✓Engine swap — VATS chassis donor ECM needs to run in non-VATS chassis
Won't fix:
- ✗No-crank conditions (test starter + battery)
- ✗Mechanical fuel pump or injector failure
- ✗Post-2005 GM with Passlock (see GM Cluster Upgrade service)
