sometimes it has to set for a day or two before it will start again.  the
battery is good but it acts like it isn't getting any fuel.  can you help?  

Answer
You have to determine if it is getting any spark to the spark plugs first.

Then check your fuel pressure with a gage.

1. Get yourself a helper.

2. remove the gas cap.

3. have one person listen in the gas tank at the gas cap opening.

4. have the other person turn the ignition switch to the ON position ONLY so as the dash lights come on. Do NOT attempt to start the engine.
