FORD 2000 3CYL GAS WONT FIRE

Thanks for getting back to me. I'm going to work on it today and I will do as you suggest. The new coil is a NAPA 12 with outside resister as the old one was. I have good spark off the coil, but I feel the spark at the plug are weak. I'll trace down the resister wire and see what I can find there. It's been a hair puller. Runs good one day and the next day not.

It's running! I hope it's for good. I checked the advance and it's working. SO here is what I did:

New points, plugs, condenser, plug wires rotor cap (even though I did the points, etc., except plug wires and coil last year) Jumped the coil and bingo, it started. Just needed to adjust the idle adjustment. Plus, after shutting off the egine for a while, it started without the coil jumper. Maybe this success was because I pried apart the 6 wire main plug behind the instrument panel which was heavly corroded. Cleaned connection and pluged back together. Anyway, we'll see if it starts and runs tomorrow. Thanks for your help!!!

corrosion certaintly didn't help anything.

as to the napa 12v coil with a resistor outside.

those 2 statements are mutually exclusive.

a napa 12v coil like a ic14sb or simply IC14 is a true 12v coil, no resistor needed. if it is one of those coils, loose the resistor. also. if you still have the oem resistor wire inline feeding the coil, you actually have 2 resistors. the resistor wire and the external one. tat would not even be good if your coil was a 6v coil... let alone 12 like you claim it is.

now. what do you REALLY have?

The NAPA coil is IC12 use with external resistor. In following the positive coil wire back to the ingnition switch, there is no resistor like ceramic. So can I assume the wire is resistor type? And if you think it is, should I run another no-resister wire from switch to + coil or return the 12 V coil and get a 6 v? There is another wire on the + coil that goes to a terminal on the starter coil.

so then you don't actually have a 12v coil.. you have a coil that needs a resistor.

i have repeatedly said the OEM setup used a resistor wire.. not a ceramic one.

the extra line on the coil to the starter solenoid is to bypass the resistors at startup.

if you are going to use a 6v coil and external resistor like you have, then you need to make sure that the oem resistor wire is not used.. it will be too much resistance for good spark. you can accomplish this by just feeding that resistor from the key. thus during starting the starter solenoid provides direct 12v, and then when running, key provides power thru your ceramic resistor.

( in reality.. no resistor and an ic14sb is what I would do.. but.... you already have the non 12v coil and most places won't take back electronics once installed.. so the best we can do is salvage your attempt. )

NAPA said they would take the coil back. I was just waiting to see what you had to say. So, do I get a 6 volt coil that is used with external resistor? The old coil reads (27310 use with external resistor). If so, I assume I can just leave the wiring as it has was before replacing it?

The OEM setup was essentially a 6v coil, that during starting got 12v via ignition bypass post on solenoid, and during run got power from the key thru the resistor wire.

You have a new coil and a resistor, and still have the bypass wire.. let's just go with that. But.. you need to make sure the OEM resistor wire is not used.
