Any engine needs three things to run, fuel, spark & compression.

Since you've checked the fuel suppy, continue on that vain and check fuel pressure (to be sure the pumps good and that there are no restrictions in the fuel line), then check the timing. If you don't have a timing light, advance the dist by turning it counterclockwise about 1/4" and see if it runs better.

If not, do a compression check and let us know what you find.

Good luck
