im having a problem with the fuel injectors. 1 and 2 spray and 3 and 4 dont i connected the injectors to the 1 and 2 plugs they spray so i know its not the injectors them self. i dont know where to start or how to identify what wires are the ground and what are the signal i dont think there getting a signal from what i understand there all grounded to the same place. could be wrong but thats what i have found out so far. also i had just rebuilt the motor ( new bearings new piston rings and new cams ) it ran for 3 days or so not drivable but it would start. so now im super confused as to what do do next. and yes i have serched and have found nothin. im hopin that someone will be able to give me some kinda help. or how to test the wires and what the meter should read. all the manuls say nothing about the harness just the injectors 2-3 ohms did that there all 3 ohms. soo some one please help me out.

 

This should help, at least tells you how to test the wires and so on and so forth
