Took he vehicle in to the mechanics and they have mentioned that the Fuel tank pressure sensor is faulty.

Now every time I look for tech help on the blazer my 2005 seems to be different i.e the mechanic also said the PCV valve is plugged. Turns out the 2005 hasn’t got a PCV valve, instead it has a small metal open tube.

So, been looking through these forums trying to find the fuel pressure sensor and some users have uploaded fuel tanks that look different to mine.

Has anyone got any pictures or step by step to find the sensor?

All the ones I have seen are in the top of the fuel pump module (top of fuel tank) held in by a rubber grommet kind of thing. There should be two electrical connectors up there for your fuel pump. The smaller one goes to the pressure sensor.

 

so I guess I have to drop the tank?

I’ve seen people mention dropping the spare wheel to access the tank, but again I don’t have a spare wheel under the tank as mine sits in the trunk

 

You'll probably have to drop the tank part way. I'm not sure how much room there is to reach it. Mine is a 4-door and it has a body lift, so I can reach up there without dropping the tank.

 

thanks, I’ll drop it slightly to see if I can see anything then.

Can I ask where you got a body lift from? Majority I have found seem to be from the US

 

I didn't use a kit. I bought the lift blocks online from Zone Offroad, then sourced the bolts locally. I didn't need bumper brackets or any of the other parts.

The only kit I'm aware of is the PA152 from Performance Accessories.
