Have checked all fuses and relays, have by passed fuel pump relay. Runs good for about 2 seconds, then shuts down
Get the car scanned get fault code
Anti-theft system problem ? Is there a SECURITY light on the instrument cluster that stay's lit ?
No security light, no shut down system
The first thing would be to check for DTC'S diagnostic trouble codes! Check B+ voltage circuits and grounds for corrosion , lose grounds etc... battery connections , cables etc... And especial the power and grounds at the PCM - engine computer ! Videos on youtube for voltage drop testing !https://youtu.be/DfLyh43iihM
