You have no voltage at 15 amp fuel pump fuse in the under hood fuse/relay center ? There is a fuel pump relay also in same under hood fuse box. The fuel pump fuse gets power from the fuel pump relay. The ( PCM ) engine computer controls that relay, gives power or ground electronically to turn the relay on giving power to the fuel pump through the fuel pump fuse. You could have a bad relay or an anti-theft system problem . What engine does you vehicle have 2.0 L or 2.2 L the 2.0 L engine gets power differently to fuel pump .

It's your Electronic Control Module (ECM). There is a short in the computer. You're going to have to replace it. The same symptoms occurred in my vehicle, had a mobile mechanic come to my house and fix the problem. Quoted me $350 for parts (used) and labor.

i had a problem similar to this. what i did was i took it to the dealership where i bought it at and it was the EGR valuve that needed to be replaced. i ended up paying about $500 for the whole thing because i had it installed at the dealership. you can order the EGR valuve and install it on your own. it takes about ten minutes to install it.

SOURCE: what does it mean when ur tc light is on in a
tc stands for traction control and usually means that something in the system is not in order, say like a wheel speed sensor. However, if the abs light goes on at the same time, it's usually a wheel speed sensor somewhere.
This could be a module or a wire to the wheel speed sensor on the tc side.
