Older vehicles run best with a gap around 40 to 45 thousandths, and newer ones can be run with plugs set at this gap with no bad side effects. The newer vehicles have more voltage available so they can run plugs up to 60 thousandths gap.

The diagram below should help.

spark plug wires or coil pack

Fred,
Did you check for spark at a plug wire or at the coil wire? Check at the coil wire,if there is spark there,the ign rotor is bad,very common to have the hot spark "drill" a hole thru the rotor to the dist shaft. Also check for play at the rotor shaft. Distruibtor bushings tend to go bad,making the trigger wheel hit the pickup coil,killing the spark.

no it will not help i think its time to buy another newer vehicle with a manual transmission its 20yrs old all but a month or two it doesnt last forever ,now if it was a manual then thats another story

just put a new starter in my 1993 chevy 454 and now i'm not getting fire, the old starter solenoid was sticking and melted the neg battery cable. I'm wondering if that also burned something else out?

if its a four cyl remove upper coveron top af engine has 6 10mm head bolts pull up the wires to find plugs-caution dont chang plugs without doing wires,the newer version has coil on plug just remove coil pack,should have four with 10mm bolt holding them on,remove bolt and pull up on coil pack

dont wish to appear rude but if you want economy a nice VW caddy,or peugeot partner.if you want larger then a ford transit ,its the best white van around ,3.5 litre petrol here in spain we would have recylcled that monstrosity years ago,Doubt if it would evan pass the emission laws here now.
