ive changed the sensor in the dist and the sparkplugs and wires! it started but i drove it for 2 days and on the 3rd day went to start it and it wouldnt crank again... does anyone have any suggestions?

 

Is it turning over fine? Any codes? Are you getting good fuel flow, or can you hear the pump turn on on when you turn the key on?

 

It didn't crank over or it doesn't start when you crank it? When was the last time you changed your fuel filter? Are you getting spark to the wires from the dist? I don't remember what they're called or if you have this type of dist. but there are some small little flint-type things (two) inside the dist. that sort of touch each other to pass charge. When the dist. twists (turns), it charges, and then these "flints" will touch each other to throw a charge through the dist to the wires. Sometimes you will need to change these "flints" if your dist. doesn't throw charge through the wires. I've worked on an older engine with this type of problem, but like I said, I don't know if this is the type of dist. that you have.
