nytro running problem

[phatkid]

Hey guys I need some help if possible

pretty sure i ran my nytro out of fuel why messing with it in the garage (new toy)

however i refilled the tank and got it to run (after cranking for a while, short bursts) however it seems like its only running on 1-2 cylinders and wont pick up and run on 3 cyl??? I pulled out the trail tank to access the plugs and removed them the gaps were all over the place the plugs were pretty good color but electrodes were pretty worn

i just got 3 new cr10ek's for it ( not installed yet)

so should i spray a little fuel down the cylinders to try and reprime the fuel rail or did I cause damage to the fuel pump??

sorry for sounding stupid but this fuel injection on a sled is all new to me

thanks for any imput ,as im gonna try and put it all back together tonight after work

I done the same with mine a few days ago. It was 15-20 seconds before it fired on all three. Try just turning the key 5-6 times to let the fuel pump kick the lines full of fuel (you will here the pump buzz for a couple seconds while turing the key one notch). I'm pretty sure you didn't harm your fuel pump. But if it still doesn't fire up on all 3 could be a plug or bad connecting with the plugs. The fuel is obviously getting to the fuel rail if it's firing on 2 cylinders though.

Put a little di-electric grease on the outsides of the spark plug boots (the part that slides into the head) and also in the center of the spark plug boot (where the spark plug actually goes). It might not hurt to blow the spark plug boots out with some compressed air as well as the holes in the cylinder head (with the spark plugs still in them so the stuff doesn't go into the motor). This will help eliminate and of the "black crud" corrosion that can sometimes build up as well. You should not need to pour any gas down the cylinders, just cycle the fuel pump several times before starting it (turn key off & on).
