Do you have spark and injector pulse? Does it pop back? Did you have the dist. out? Not much info provided here.

Not much info provided here.[/quotie] fuel pres was good then i had to chahge starter first was ng afterthat and changing cam sensor in dist i had backfire through throttle body( this has the spider injecters under plenum) any way the dist caps on yhese are not round 4 wires come straight out each side the dist cap looked fine by the naked eye but i ohm tested from where spark plug wire goes and traced were it would fire inside the cap . the spark was jumping to diff cylinders inside cap so changed cap rotor and fired right up pretty wierd huh?
