My 02 Silverado cranks up then shuts off right away it has 193000 miles on it security light in dash came on no codes are anything stayed on one week changed to better factory key everything ok then
Done 30 min reset test two times
didn't work light went out though
read after 100 cycles ignition clears
about 3 days later truck would crank
up then shut off every time replaced
fuel pump ,filter ,regulator because
of mileage and shutting off still does
that can't figure it out going to get
pressure tester tomorrow but can
feed gas in throttle body and runs as
long as I'm doing that any ideas guys
and girls thanks
If fuel pressure turns out good,then check the crank sensor,if sensor is good,it will be the fuel injectors.
Check air filter and clean Throttle Body and the Idle Air Control Valve.
It really sounds like the pass key problem (security)
