as the title says my truck stalled on me shortly after starting it. I was driving up hill and suddenly lost power and it stalled and i cant get it start. I replaced the fuel filter, made sure the fuel pump was working, i replaced the spark plugs and wire. i changed the rotor in the distributor. im at my wits end. I cannot figure it out. I tried to check and see if there was a spark but i felt like i was doing something wrong and it wouldnt work. I grounded the threads and tried to turn the truck over but it wouldnt spark. happened with all of them. if anyone has any advice it would be much appreciated. it's a 1990 toyota 4runner v6 3.0
