Question about 1991 Isuzu Rodeo
The backfiring is a sign that the distributor is indexed improperly - or the plug wires are mixed up..
First, you need to set the engine at Top Dead Center on compression stroke.
Easiest way is to take the distributor back out first - then pull number one spark plug, put your finger over the hole and bump the starter with a remote switch or someone at the key.
When air starts to push out, then look on the pulley for the TDC mark coming up on the pointer - line that up.
Then locate the 2 dots on the distributor shaft, one on the shaft by the gear, and one on the gear - line those up. OR - find number one post on the distributor cap, and make sure the rotor is just getting to the number one post when the distributor is seated in the hole. If not, just pull the distributor up enough to catch the next tooth until it is sitting properly.
Let me know what happens please. The more details the better. Good Luck
