Need help with my 460

Post  RedWing21 on December 16th 2014, 12:39 pm

Hey guys im new here and i just purchased a 1968 f100 with a 460 in it. When i got the truck it would fire right up. Now when i go to start it all it does is just crank over. It has spark and is getting fuel. I just can figure it out. Any help would be appreciated and let me add this I don't know to much about fords. Thanks

Have you pulled the spark plugs out if you have are they real black or wet looking if so replace them and try to fire it up might have flooded it and killed the plugs.

Air, spark, and fuel... Unless your under water, its got air. Fuel.... ENOUGH???? Give it a couple (few) stomps to the floor, then leave your foot off the pedal..... That will dump a few pump shots into the engine, and set the choke if equipped... see how that does.

Lastly spark. Here is the trick, one spark on coil power up, could be a couple problems. Repeated spark when cranking, all else ok, try adjusting timming... Move the distributor while cranking to get it to fire. Some people leave the distributor a little loose and it will walk off time on you.

Thanks for the advice. I pulled the plugs and they were black and soaked from fuel so i cleaned them off, put them back in , put it to the floor 3 times and it fired right up. Thanks for the help.

glad you found the problem sometime the carb engine can be hard to crank on cold days my 69 F100 is hard to crank if I let it sit for awhile or on real cold mornings but I don't run a choke on mine usually take 3 or 4 times to get it to fire off once it fires up it crank good until I let it sit a day or 2
