i have a problem and cant find the answer. i just got and xcellerator and the first time i tryed it it wouldnt start. i took the fuel out and called it a day. before i put it away, i tryed to start the engine to remove extra fuel in the lines and the engine started. i put fuel back in the tank and it did not work. so i repeated the before of removing the fuel and starting the engine and it started but i was too tired to fuel it up and try again.

so a week later i tryed it again, it started fine, i let the glo plug sit on for a minute, took it off and the engine went dead. the i got the car to the point where i coul take the glo plug off and the car would either die a couple of secounds later or when i tryed to excellerate it would die. i decided to call it quits for the day and removed the fuel and started the car and left the glo plug on the car and it went, it worked.

why does it only work when the fuel tank is empty?
