Alright so, 2 weeks ago check engine light comes on and I find this p0230 code talking about the fuel pump main circuit. I try the easy culprits first, swapped relays and checked fuses everything fine. I saw online someone had to repair their crank sensor connector, but mine is seemingly fine...I wiggled it and left it....day later the light went out and a day after that came back on. To see if me wiggling the connector caused it, I wiggled it again and even cleaned off dirt and oil residue, didn’t fix it.

So I am back at square one. I have only VERY BASIC electrical knowledge and I just need to know if I may have to replace the fuel pump. I did replace it back in 2017 and replaced the connector and it wasn’t fun especially with a full tank.

if I have to do it again I will cut a hole in the floor to get access before I drop the tank again.

so does anyone have experience with this on the 2004 RWD Blazer? (I know the year barely matters)
