Hi everyone I’ve encountered this issue where my car would turn on instantly and then die, fuel pump will prime check engine light will turn on for 2 seconds and then turns off like normal, it comes back on bc I don’t have my downstream o2 connected but it turned on before even with that issue, I don’t know what to do at this point I’ve disconnected the map sensor the IACV sensor I’ve checked all the fuses none are blown or not giving voltage like they should I have no idea what’s going on

 

what are your fault codes? I would check the amount of fuel pressure at the rail. It may have a bad fuel pressure regulator or bad fuel filter. This is where I would start. Also check the condition of the cap and rotor on the distributor.

 

What shape is the key cylinder in?
