I Have a 1993 4 runner I just bought. I bought it not running. I replaced the fuel filter, fuel pump,(Last owner fried the fuel pump using a wire from battery to fuel pump) plugs cap and rotor. The truck isnt throwing a code and i don't know wha else to check. Converter is good also.. Thanks for any help!!!!!!!

 

check firing order and ignition timing

 

Did you check the timing? Did the guy you bought it from give you any history?

 

No history except it was a one owner and the timeing belt was replaced about 20thousand miles ago. It set up without running for about a year. He replaced the fuel pump but it would not run so he ran a hot wire to it to get it to crank but that burnt up the fuel pump. I replaced several fuses a 2 relays fuel filter and the fuel pump. Cranks rite up and idols fine but it loads up when u give it gas.

 

Could even be a vacuum leak. Make sure all the lines are still connected. Just like a kid in a candy store, so many choices of things to try.

 

I have checked the vacuume lines havent been able to find one leaking but who knows I am at a stand still, I don't know what else to do. Guess I will just have to put it in the shop.

 

test the afm or tps u can find the way to test them in the fsm and that can be found here... http://www.ncttora.com/fsm/index.html
