Fuel pump problems?
 

Hey there, I recently bought a 1999 Volvo S70 base and my car has been sputtering and sometimes just cutting off completely and having difficulty starting. I looked up the symptoms and it all pointed to the fuel pump. So I bought a new fuel pump and replaced it myself. After driving it for a little bit, the stalling out and sputtering continued to happen. I go down to the local parts store to explain my condition to the employee, and he says to replace the fuel filter and run some fuel cleaner in it. It drive fine for about a day and it's back at it again. Last night the car wouldn't even start at all, and the check engine light came on and so did the ETS light. If anybody can provide some help, I'd greatly appreciate it.

If your ETS light is on then it is your Throttle body. Common fault in 99-01 s70. These years they switched to an electronic throttle body which is known to fail. Essentially a moving part inside the throttle body wears out over time from constantly being rubbed. Symptoms include tougher time starting, stalling, limp-home mode, severe loss of power, pressing gas does next to nothing. It will start off as stalling typically, but will get worse over time.

Only way to fix it is to either get a xemodex throttle body, in which they have completely redesigned the failing part so that it never fails again, or someone recently showed me this from ARD;

ETM Repair Kit
Xemodex Inc. Technology Improved

I have been threw this personally so if you have any questions let me know.

So I looked at the Xemodex module and ruled it out due to it costing so much and instead bought a Sacer ETM repair kit. I've looked online all over for instructions on the installation but I haven't found anything to be helpful (more like an actual guide on how to install it) so if anybody has any leads to finding these instructions I'd greatly appreciate it.

Forgot to reply :P

Looks to be same thing like the ARD unit. I couldn't really find a guide so to speak, but I found this with some pictures;

I would keep looking on the internet.
