my tuck will start and run but when you push on the trhottle it will not do anything, i bought a new tps and put it on and still nothing. all this happened after i put the d fuser aic on my truck

 

the what???

 

I think I remember your other thread. Did you check fuse #3 (3A) as it protects the IVS (idle validation switch)? The IVS is down there by the TPS and when you push on the peddle you should hear it click. I believe it's a red button type of switch.

 

so i bought a throttle assembly off a truck at a junk yard and put it on and it worked so everything is all good now

 

I bet it shorted out the ivs
