Blazer does not start

[81_chevy_4x4]

Well after my 83 jimmy sat for 6 months i decided to work on it over the weekend. It was getting almost no fuel and no spark. i put a new fuel pump on got plenty of fuel. then started looking around i knew the wires were shot fond a hole in the cap i could stick my finger in. so i replaced the wires, cap, coil, and the rotor. Still no spark so iwent to my buddys house and "borrowed" condencer and module from under the cap(its an 81 chevrolet thats sitting in his back yard). the module was different than mine so i did not put it on but i put the condencer on. we went to check for spark and it started without that plug hooked up so we hooked the wire back on and put the breather on and drove it down the road it ran great. then i got home and realized my tags were out and then parked it in the drive way. got my tags today and went to start it to come to work tonight it just cranked over would not start like it was not was not getting spark any more did not havbe time to mess with it witout being late for work. Any body have any advise. me or my dad ddoes not why it does not start

I cant recall when gm started using the electronic control dizzy but if the one you have isn't a standard hei i would swap it out.

If the factory set up is on their you have a ccc carb and dizzy set up.


Best option is to truly just swap it out,


Read up and search google on computer controlled carbs, lots of good info.

I have 1984. when I swapped out carb I had to change dizzy. I got a Mallory unit. all is well.

you might not HAVE to get a new distributor. if you pull the cap off, there's a rotor button in there that MIGHT have gone bad. i'd check that before you go about gettin a new one.

sorry...what your looking for is the ignition module. that is located UNDER the rotor button. your local parts store should have one. what happens is, when that ignition module gets moisture, you won't get any spark. replace this, along with the goop they give you, and you should cure the problem.
