How do i wire up an electronic ignition in a 1970 Ford F100 that was originally on a points system?

How stock is ignition and charging system?

Assuming stock ignition, check for near battery voltage (within 3 volts or better) at the positive side of the ignition coil while the ignition switch is in the run position.

If no power at coil positive then likely a fuse has blown or other open circuit... miswire or open ignition coil resistor wire.

If power at coil positive, check for power at coil negative. If near battery voltage at coil negative then points are open and you should get spark at ignition coil secondary by flashing the coil negative with a jumper wire to ground.

Comment for further assistance.

I have a 2004 kia sedona that will not start been told its immobilzer in key

It may be the sending unit in the tank that needs replacing. Here's how you can check: Turn the key on and disconnect the sender unit at the gas tank. Ground the sender unit's wire with a jumper wire from the truck's harness to ground. Watch the gauge. If the gauge on the dash is good, grounding the sender wire will cause the gauge needle to react and should move to full. This would indicate a new sending unit is required. If the gauge doesn't move when the sender unit is grounded, the gauge is bad and needs replacing. Pull the instrument cluster out to replace the gas gauge. Likely any old ford gas gauge might work-back then, there were not so many production changes.

check to make sure you have power going to sending unit on the tank,if yes,make sure you have a good ground.check all connections.As long as the float has not broke off the sending unit inside the tank, you should be able to fix it easily

It should however you may need to use the mounting bracket from the 79 there bolth 302 ;s it should work

Look on E-bay for an electronic CD unit that fires from the original points, but generates about 400 volts to fire the standard coil. My guess is that there is no all-electronic ignition system available even as a racing option. Ford used this engine in the Pinto line of cars from`'71 to `73, and all of them used points and condenser distributors. The points and condenser units work fine if in good order and the point gap set at .025". Hope this gives you an assist!

If it will mount on the vehicle,cause the one wire alternator is a delco,just hook up the large cable on the back of the alternator,that`s all.

The only place that I know that has a wiring diagram is the factory shop manual which is available thru any thunderbird restoration parts suppliers or ebay. If the electronic ignition, they called it transistorized ignition in 66, is original, you might consider changing to a point type ignition or a later electronic ignition or aftermarket like Petronics. The parts for the original transistorized ignition are very hard to find and even more pricier.

Change your coil....

This sounds like a telltale choke issue. You running carburated right?
If it is what i think it is you have a choke thermostat on the carb. If so check the votage on the wire and if you have power then the choke thermostat has to be replaced. you can do a manual set of the choke behind the carb just to see if this is the problem.
