Question about GMC Cars & Trucks
Replaced distributor cap and rotor exactly location.
Check the points....make sure the gap is correct with a feeler guage. If you don't have a feeler guage, you can get close by using a matchbook cover as a guage. Also, check the engines timing. It could be that it jumped time....if the timing chain slips just a couple teeth, your engine will not start.

SOURCE: ROTOR BURNING UP
The rotor is somehow making direct contact with one or more distributor contacts.
Check the contacts inthe cap to see if you find any physical damage to one or more contacts caused by the rotor.
Could be rotor lead too long (file it down) or maybe the distributor shaft is bent or not seated. Remove cap and observe the distributor shaft as someone cranks the engine. Does it wobble? Can't tell? Place a stiff reference parallel to the shaft and turn engine again.

To replace the Distibutor cap and Rotor [they fit together as a unit when you get the two parts together]. First you need to mark with masking tape [or other such tape you can write on] the number of each spark plug wire and attach the tape firmly to each wire. DO NOT make any mistakes! Make sure you are numbering each wire with it's correct number based on the spark plug w/ wires position! Depending on if you have a 4,6 or 8 cylinder vehicle you will have 4,6, or 8 spark plug wires/spark plugs, and each has it's own number. You'll need to find out which is the number one plug ,number two plug, number three plug until you correctly number each one! You will end up with wires [either 4,6 or 8] going around the Distributor Cap. The one in the middle of the cap is the "COIL WIRE" leave this one unmarked cause you'll know that one stays in the middle. NOTICE- YOU need to positively find out which plug is which number with a VEHICLE MANUAL that shows you clear photos/diagrams of which plug/wire is which and i'ts position on the cap. Once you ID each wire then you need to mark your new DISTRIBUTOR CAP with the exact numbers in the exact place as the wire was.Now you can remove the wires off the old distributor cap and remove the cap and old ROTOR. Put the new ROTOR in. Place the CAP in the correct position as before and place the NEW Spark Plug Wires in there correct places based on the number you put on your New Distributor Cap.
