I have an '86 camaro with a 305 5-speed, it was running rough because i just started it and was warming up and it was idling and just cut out completly. The battery is still fully charged, lights work fine, the ignition does not buzz anymore when the key is in. I have no idea what happened but any help would be appreciated. The starter, alternator and battery were replaced within the last two weeks. Any ideas on what the problem is and how to fix it would be a great help. Thanks.

 

Check your fusable link and the fuses for the starter and ignition. Also check your starter motor relay.

 

I don't see how that would be a starter issue. The only way it might be a starter issue is if the power cable is loose and causing it to not get enough spark. Otherwise, you're looking at an ignition or fuel problem. First thing I'd do is replace the fuel filter and see if that helps, and check the draw on your fuel pump. The pump should be consuming 12 volts, while the rest of the circuit should be taking about .2 at the most. If anything on there has a draw of more than .05V, replace it or clean it. You should also check plugs, wires, distributor cap and rotor, and power to your ignition coil. Keep us updated, I've got more things to try, but those are the likely ones.

 

check your ing. fuse under the dash an like fluffy said find your self a volt/amp meter and check everything to see if your getting a draw some where

 

Sorry I didn't have time to elaborate earlier, but the quickest way to check an entire circuit (except for grounds) on a NON-COMPUTER circuit, is to get your Digital Volt Ohm Meter (DVOM from here on out) and place the negative lead on the negative battery post, and the positive before the load (whatever the circuit is supposed to run, I.E: a fuel pump, a fan, lock actuator, etc. You should have about 12 volts at that point in the circuit. If you don't, go backwards through the circuit and find what's giving you the drop. If you DO have 12 volts, check the ground side. You SHOULD get a reading of close to 0, anything higher than 50mv means there's a short in the component, and it should be replaced, UNLESS the reading is almost up to source voltage, which would mean that you likely have a bad ground. Ground circuits should be tested with the negative cable off, and your DVOM set to resistance or Ohms (it's the funny looking horseshoe thing, otherwise known as Omega) run the positive lead from the outlet of the load in the circuit in question, and then place the negative lead on various spots throughout the ground circuit to see where the resistance shoots upward. That'll be your problem spot, if it's a ground issue.
