I'm getting ready to buy my cousins1990 gsx, and he took all the plug wires off before he got the new ones so now we have no idea what the firing order is. Can anyone help?

 

I believe this is the order with the first # being from the distributor and the second number to the spark plug looking from left to right

This was for a 2g sorry, see post below
#1 Dist - #2 Spark plug
#2 Dist - #3 Spark plug
#3 Dist - #4 Spark plug
#4 Dist - #1 Spark plug

Try that and see if it works

 

scratch that. I was thinking this was a 2g. Here is the 1g firing order

 

thanks, thats what we have it as but for some reason it wont fire now. and im pretty sure there is a boost leak. this is definately a project car.

 

welcome to owning a DSM

 

hello! look closely at the coil. on the metal bracket that holds the actual coil will be stamped the firing order for each plug wire.
