man, this thread has turned into a mess.

to the guy with the '83 and fuel tank issue...are you sure there's supposed to be a resistance wire there? that wouldn't make much sense.

to the guy with the black wire...measure your voltage at the coil with the truck running. there's no other way to know.

both of you might be better off creating separate threads.

 

Oops. Did that already it's a resistance wire that's WHY I asked anyone seen a black one No need for new thread for that

 

I won't interrupt another thread bud

 

Resistor wire runs from the ignition switch to the firewall and yes, it is pink. If it is black, someone removed the resistor wire and replaced it. Start your truck and if there is 12 volts at the coil, it is too much. There should be only 7-9 volts when running.

 

I've got a little over 7 volts thanks.

 

I have a resistor wire acting all funky between my fuel pump cutoff relay and tank selector relay. its looking like garbage and I know that resistor wires are funny to replace. I have another thread just thought this one sounded helpful... ill start a new one in the future

 

D7AZ-12250-A .. Resistor Wire-Ignition Coil (Motorcraft DY-213).

49" long / Color coded red with green stripes / 1.30-1.40 ohms resistance / #16 gauge wire.

1977/91 F100/350, Bronco & Econoline.

There is no such thing as a black resistor wire.

 

mine is/was pink and black, far as I know. but the problem is I'm getting power/resistance correct on the wire I'm just not getting it in the actual relay if that makes Any sense... anyway thanks

 

correct me if i've misread your question-
you're asking about an electric fuel pump relay on an '83...but this is a thread in the 67-72 forum about the ignition coil resistance wire...we're talking about completely different things.

i'm all for trying to help, but this is just the wrong spot. none of us have OEM electric pumps, fuel relays- any of that stuff.

there's a lot of user activity in the 80-86 forum- i'm certain if you post your question there, those guys will absolutely be able to help you out.

 

Could be wrong but never saw black resistor wirer, even aftermarket. Wondering if your getting full voltage at coil. Pink resistor wire should go from + side of coil to a 3 prong connector under the dash. There is a hole in the fire wall on the other side is the three prong connector used for bypass wire, pink resistor wire, oil pressure, temp sensor. Pink wire should go from connector to the iginition.

If your running full voltage to a stock coil you can burn it up quick. Should be getting 8-9 volts at coil with correct resistor. Might be worth checking before you get stuck somewhere.

 

You guys are right. I rubbed on the line it was painted black. It's a pink resistor.

 

Just gotta love the PO's.
