forgot to mark the injectors on the rebuild...what ones go where?!?!?

 

someone correct me if I'm wrong, but the enignes are batch fire, so left side, lef, others right. They should "fall" towards which ever side they've been on for the last decade+

 

 

heh........trial and error i guess lol

 

The wires are old enough and the wire lengths are specific enough that you can just lay them down and they will basically fall into place. I didn't mark mine when I did my 3.4 swap... I had no 2nd thoughts about what went where.

same here, i have never labled them. if you place the other connectors on that harness where they go the injector wires should be close enough to figure out.

and project: they ARE batch fire. left side right side. on my TPI it's the same way. infact about halfway up the harness the one wire splits into 4 (or 3 on a v6) and goes from there.

 

what do you mean by batch fire....i remember if i looked correctly, that one of them split wires had 4 on one side..?

 

batch fire, all the injectors on one side fire at same time, ten other side fires at same time

 

how the hell does that work....i cant make sense of it.....i believe you and all i just dont understand it..

 

About every i think it is 180 degrees of crank rotation 4 injectors pulse ( left or right side), then the next 180 the other side will pulse all 4.. continuous pattern

Although i think the v6's are SFI?

 

so it seems as if that there is being gas used improperly??? confused!

 

Yea, gas is wasted with MPFI, and SFI didn't come out until '93 with the 3.4s in fourth gens. SFI only fires the appropriate injector for the cylinder that is going to be fired next. Thats why the heavier 4th gens with the bigger v6s still had good MPG ratings. Another reason to swap to that setup besides the speed density benifit.
