fire

[matt628]

Can any one help me I hav no fire on cylinders 1-4 what could this be. I used a test light on the wires comeing out of the box an when you crank it over they all work up to the coil packs the plug wire have a good light on 2-3 but 1-4 the light is week could the. Coil packs hav gone bad.

probally bad coil 1 and 4 are on the same coil there is a resistance check you can do to verify if the coil is bad

Check your caps on that coil; the caps screw into the wire, the joint can degrade, and you might have to trim it back 1/2". The cap itself might be bad; check with an ohmmeter (5k, I believe - check the manual).

Quick & dirty change the the input leads from 2&3 to 1-4 seee if it sparks then if yes its the TCI if no its the coil pack in most cases.

I got a new tci off ebay. I took the old one apart an it was burned when I got the new o.e today I took it apart an nuthing is burned. But u still hav no spark on 1-4 I trimed the plug wires down still nothing any help would be very app

Did you check the coil resistances, as haro advised?

Did you swap the input leads, as Geo advised?

Did you check the cap resistances?
