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.
