Starter Bad?
I just bought a 1979 F-250 I6, 4.9L 300. When I bought the truck it fired up right away. It fired up about 10 more times that day on the long 240 mile drive home. No problems whatsoever getting home. No issues starting at all. This morning I fire it up and turns over quick. I end up cutting it off and when I get back it won't fire and all it will do is click a little. I tried jumping it....No Go either. Could this be the starter???

Bean, it could be the starter or it could be the starter relay. Usually on a fender well ther is a starter relay, about half the size of your fist, ther are two large wires attached to it, one frome the battery and one to the starter, and two smaller wires from the ignition starting system. This could be bad as well.

I'm with those on the bad connection thing. Replace battery connectors with one piece units that run from the block to batt, and solenoid to batt. I hate those 'replacement terminal ends'. they are a disaster waiting to happen.

Thanks
Mark,
Thanks for the reply. After fooling around with it I ended up trimming up and cleaning the connector cables and she fired up. But it is not firing perfectly, in fact it seems I have to find just the right spot and then it fires. Do you think that is still the connectors?? I'll check into the one-piece units. Does Advanced have those??
Thanks again,
Dave

One thing that few people know is that molded cables can corrode inside under the insulation near the cable end on the battery.
This can get very frustrating as the cable looks great from the exterior but inside only a few strands are clean.

I recently had to change all my 4 guage positive wiring because of rot in the copper wiring. It's not a bad idea and should help a lot. That would be from battery to relay to starter and my negative also. Splicing in some fresh wiring around the relay couldn't hurt. Just a couple of hours work, and a world of difference.

Yeah Dave, I would lean towards the fact that you still have bad connections. Replacing all your heavy gauge wiring is a good thing, and it's inexpensive. If you can find the engine to chassis ground strap, clean up connections or replace also. If anything, you will have great piece of mind. I get lazy with that sometimes, but after the occasional 'parking lot blues' session of wiggling wires to start the car, I get mad and finally remember to buy new cables. So, all my vehicles get new ones at the first sign of bad corrosion. Keep in mind, wires still fairly new can be cleaned with water and baking soda. You can then spray a weather protectant over the connections, available at most parts stores. Mask your battery so it doesn't look 'Ghetto' after spraying.

79 F100 4.9L Automatic C6
My 300ci inline-6 engine features a 9-tooth drive gear with a clockwise (CW) rotation.
I went on line and was told. No, the starter drive assembly with Ford Engineering number C4DZ-11350 (often ending in -B) is not a direct fit [1, ] A Ford Engineering No. C4DZ-11350)Flywheel/Tooth Count: The starter bendix gear spacing and tooth pitch do not match the flywheel and starter motor used on the 1979 F-100 4.9L truck engine.
What you need instead: For a 1979 F-100 4.9L engine, Automatic Transmission Starter Part Number: Standard parts industry index 3124. Buy a starter assembly (or starter drive repair kit).
I know it takes a 14.25” Flexplate. My starter research has said I need a 3124 Starter, but all the Auto Stores said I need a C4DZ-11350. Now I don’t know what I need. It sounds like the starter is going to ripe out. What is the correct starter for this truck?

Do you live near any auto parts stores? If it worked previously, any chance to remove it and get to the store to compare to what their listings show as the correct one for your truck would be a good start.
Pull any new ones out and compare to your old one.
Or did the one you have never work properly?
