Maybe it's your hydro power.

Check your flux capacitor, halogen fluid, muffler bearings and homogenizer.


You probably have something wrong with the wiring since you didn't label it before removing it all. Check the FSM for a wiring diagram that tells you which electrical plugs go to which tabs at the ECU side of the EFI harness. Grab your OHM meter....happy hunting.

It could also be the nut holding the steering wheel.

Don't be joking about that left-handed stuff. I might get offended, us lefties are being discriminated against........ Seriously, I actually do have a left handed crescent wrench. (not crescent brand tho).... swap meet special.

Go look at which direction you move your thumb to close a normal adjustable wrench. Mine is opposite.

I'm still looking for a left handed coffee cup. ie: look a which side of a coffee cup the picture, or saying, is on when you hold it in your right hand. I haven't seen one for lefties.

Oh, YEAH, you won't believe how many times I've designed $**** that works perfect for me, but I have to redesign it and remake it for the retarded right handed people that can't adapt to the left handed man's world..... Geez, get a clue.

soldered new ones on it perrs now, but cylender#6 isnt i dont no why, it

looks like its firing after looking at hte plug it wasnt fuel soaked or fouled

but i changed the coil pack and still nothing when i pull the wire off the

coil pack ,i even changed that coil wire, still nothing dont no wat else it

Check the resistance on the injector. Also check the connection at the injector. You could have the same problem as what you had with the other connections.
