The firing order is the same, 18436572
But, depending on who made the engine, the firing order may go cw or ccw around the cap. You need to check which way the rotor turns when you crank it, then follow the firing order in that direction. Sometimes the number 1 spark plug tower is marked on the cap, if not, put the number one cylinder on top dead center of compression stroke, which ever coil tower the rotor is leading into is number one, then follow the firing order in correct direction of rotation. You driver side cylinder bank should be numbered, 1357 from front to back, passenger side 2468, front to back.
If you replace plugs and plug wires, one at a time, you won't have this problem. Goodluck.

FIRING ORDERS

To avoid confusion, ALWAYS replace spark plug wires one at a time.

The most important thing to remember about the removal and installation of a distributor, cap or spark plug cable is that all wires MUST be labelled before they are disconnected. Keep in mind that these figures depict a firing order where the distributor cap terminals are relative to EACH OTHER only and they do not necessarily depict the tower positions in relation to the rest of the engine. This is true because any distributor which has been removed and reinstalled may have been installed with the No. 1 spark plug tower at any position (360 degrees) in relation to the rest of the motor, as long as the rotor aligned to the No. 1 tower when the No. 1 cylinder was at TDC of the compression stroke (valves closed, ready for the plug to fire). As long as the remaining wires were connected in the correct firing order sequence (depending on direction of distributor rotation) the engine will run. DO NOT EVER remove more than one wire from the distributor cap at a time unless you tag ALL wires and towers to assure proper installation.

you can keep trying but unless you know what to look for and what tests to run i would advise you to call a local mechanic to have a look,this age of vehicle has a module ,it could be that ,fuel problem ?? as well so unless you know a lot about cars call a professional to kick it in the right spot for you
