Took spark plugs off to replace and didn't write down the order in which they came off. Now we need the firing order; 1986 Dodge Diplomat, 318 V8 2barrel. Can you help?

What is the firing order for Dodge 318 or 5 2L

The firing order for a Dodge 318cid/5.2L is 1-8-4-3-6-5-7-2 clockwise rotation.
Cylinders are numbered like this.
Pass side 2-4-6-8 front to rear.
Driver side 1-3-5-7 front to rear.
The firing order is probably forged into the intake manifold. Number one tower on the distributor cap is the one facing the number one plug or the driver-side headlight.
Distributor rotor at Number 1 plug terminal points to front intake bolt on left side of engine.

You could have 3 different engines in that rig.
The firing order is 1-8-4-3-6-5-7-2 for most Dodge 8 cyl engines.
And the odd cylinders are on the driver side.
The small block engines ( 318 ) have the distributor in the back, and the big block engines ( 360 440 ) are in the front.
The rotor on the big blocks turn counterclockwise. The dist cap is usaully stamped with cyl 1 as a starting point.

FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

if it is a V8 318 engine the firing order is 1-8-4-3-6-5-7-2.....cheers

did you change the main coil and coil wire?if so then check the ing resistor and then the computor box

The order should be stamped on your intake manifold right under the air cleaner.
My '97 1500, 5.2, 318 firing order is 1-8-4-3-6-5-7-2

Hope this helps
