hello having a small problem did nmy swap car started fine for about 5 minutes then it would die...tach would be jumping all over but car would be idleing....now it wont start and when i try to start it the tach and speedo jump all over but it wont start.....help

 

Check your timing. Sounds like Dizzy problems, Maybe Ignitor. Look to see if you getting any spark. You have grounds at the tranny, thermo housing (for main harness) , and valve cover

 

yeah, as sayd above, check the wires going to the ignitor, sometimes they come loose and give the jumpy tach symptom
