the spout connector is a 2 wire conector near the dist. that looks like it has a "cap" on it. the cap is pretty much a jumper. if this circuit is open it will run on base timing. check that connector and the wiring to it first.

edit: the spout may also be by the drivers side hood hinge i cant remember...

thanks mate. ive sorted the timing and still ran rough.i noticed plug 2 was sooty and others were worn out so replaced plugs rotor cap and leads. cylinder 2 is not firing but has a spark. the plug is sooty but not wet so now starting to wonder if its the injector. i dont own a compression tester but she sounds ok on a polish test.

is injectors a common problem with these trucks?

thanks for your help
