Press primer until fuel fills bulb and flows out carburetor. If no fuel in primer bulb then check connections.
Check fuel line connections by disconnecting retun line to tank (without filter) and pressing primer bulb. Fuel should draw from tank (filter), into bulb, out bulb to carb and expel out carburetor. If not the bad lines, filter, or lines not connected correctly.
With fuel primed, turn both high and low speed needles in (CW) until seated, do not tighten. Then turn needles out 1 1/2 turns for initial settings. These settings are only to get unit running. Increase idle speed setting if engine stalls. Adjust low speed, then high speed and lower idle speed back to normal.
Testimonial: "did figure it out-ignition coil failed"

sounds like its not getting its initial shot of fuel to start. thier is either one or two sensors that control that. go to your local auto parts store and they can tell you more and get the right part.

Uncouple the fuel line coming from the pump at the carburetor, place a clean can under the line, and have someone operate the starter--you should have fuel shoot from the line in spurts as the engine turns. If it does, then the entry port on the carburetor is plugged. Remove the float assembly and pull out the float needle valve. Hook the fuel line back to the carburetor and try the starter again, there should be fuel pumping into the float bowl. If not, check to see if there is a filter on the fuel inlet path that may be plugged. If no filter, remove the float needle seat to see if something is blocking the fuel passage. If all else fails, use compressed air to blow backwards through the needle seat (remove the fuel line again). Hope some of this helps!

You'll need to see if your fuel pump is providing fuel pressure. First test would be to take off fuel cap, listen through filler tube as someone turns ignition on for a few seconds, then off for a few seconds. Repeat a few times you should hear the fuel pump start then stop as it builds pressure.
No noise, then test voltage coming to pump if yes, 12 volts, replace fuel pump. Test ground also before replacing pump.
I would expect it to be this as the computer wouldn't allow the vehicle to run with fuel being poured into the engine otherwise.
If it's pumping, you will need to do pressure testing to determine if it pumps enough, or just replace it as either just the pump, or the complete pump assembly that drops into the tank rather easily.
Pumps are available at dealers OEM, discount auto parts stores, and I've had good luck with pumps that I've bought on eBay.
good luck
