Question about 1989 Ford F 250

1 Answer

Ford 460 - no spark

I've got a 460 in a 38' RV. The previous owner left the ignition key on for a few days and burned up something. I've replaced the distributor (with pick-up module), the coil, the ignition module (on firewall), and still no spark. I've got 12v at BOTH terminals of the coil, but can't find a ground problem either. HELP!! I have an 89 F 250 with the 460. The water pump went out. I replaced the water pump and now the truck won't start. There is no spark. I replaced the coil and still nothing. What is the next step? It's fuel injected and I was told that it still has points that I should check. Is that true?

    I replaced the ignition module and now I see the inside the distributor it is not turning. Hopefully I can just replace the distributor assembly, but I have never heard of this happening. How does the distributor come out? I turned it to put on the new module, but I don't know how much it needs to be turned to pull it out. Thanks

    I pulled the distibutor and the cam shaft gear is not turning. The truck turns over so I am wondering if it the cam or would it be the timing chain. I've never heard of a chain breaking, but I'm sure it's possible. Any suggestions? I am assuming I have to go into it as if the timing chain needs to be replaced. Thanks for you help.

Since the distributor is in the front on the 460 and you replaced the water pump check the connection plug coming from the distributor. If you disconnected it when removing the water pump you may not have made the connection tight enough to complete the connection. Look for pinched wires also. And your engine does not have points. You have a breakerless ignition system in the distributor. The air gap should be set at 8 thousands of an inch. Check the gap. Good luck.

    Don't replace the distributor. You need to remove the distributor now. Remove the small bolt that holds the small keeper plate aganist the distributor shaft. Turn the distributor back and forth while lifting the assembly up and out. At the bottom of the distributor should be a gear. This gear sets in the camshaft gear and that is what turns the distributor. Check to make sure the shear pin that goes through the small gear has not broken. If the shear pin is broken then you need to replace the shear pin. Also when you replace the distributor you will need to set the engine up on top dead center to time the distributor correctly. Also there is a slot in the bottom of the gear that needs to be aligned with the oil pump shaft down in the hole the distributor drops into. When you put the distributor back in you must get the oil pump shaft into the slot for it to work correctly. So ,as you place the distributor in the hole you will need to turn the rotor back and forth slightly to engage the Shaft. The only other scenario would be that the timing chain has broken and you would have to replace it to get the distributor to turn. After you replace the distributor leave the cap off and crank the engine to make sure the chain is good. If it is still good the shaft will rotate in the distributor. If you need more help feel free to write again. We are always here to help. I need to see this one through with you to make sure your problem is resolved. Let me know where you stand after this next step. Good luck. Follow the directions and you won't have any problems. Have a great day.
