Dear Ron, you have replaced fuel pump and fuel filter. You have checked the fuel pump relay. Still no fuel in rail. Try bypassing fuel relay with jumper from batt to fuel pump. If o/k then check computer for ground to relay. This system uses a relay that is operated by the computer that supplies a ground for the relay to operate. The wire color is green,16 gage. If the ground is not available then "no fuel" Check this with a test light. Key on and crank apply test light to ground wire and other end of light to ground. You should hear relay click and get fuel. If this checks out you will need to replace computer or get creative with rewiring the relay so it works without computer input. Good luck Moe

Possibly you have a porous sump in the fuel tank.

SOURCE: it starts fine, runs 20-30 seconds, runs rough,

check the actual fuel line. Also is it fuel injection or carberator
