hey i have a 1984 ford F-150 with a 351 5.8L engine. with 93,000 miles. ok i recently bought this truck and i got it running with alittle work due to sitting around by replacing the battery, alternator, and battery cables. and other odds and end things. after getting it home it went out again and i tested the battery and found out the solenoid went out so i replace it and it ran fine. i have since drove it for about 200 miles and replaced the P/S pump on it and then it quit again. everyone i asked said it was the starter so i replaced it as well. it still doesnt start. i am not the best person at cars so i need some help. i checked doing the crank shaft thing to see if it was locked up so i am pretty sure it isnt locked up, but i dont know what else to do. any help would be awesome.

thanks,

well i'll give it a shot
1. does the motor turn over?
2. do you have spark? pull wire off plug put screw driver in the end and have someone crank engine if sparks or you get shocked you got fire. :lol: red neck joke
3. do you have fuel there is a tap ontop of fuel rail close to the distributor it has a black plastic cap on it take it off and turn key on push on center if gas comes out we can assume you have fuel at this time pressure is another issue.
4. if motor doesn't turn over i need to know this
check all these things first . return here and let me know. (NOS) we can go from there

well the engine doesnt even sound like it is trying to turn over. i try to turn it over and the solenoid just makes a buzzing noise and then quits. i tried to jump it off thinking maybe if i added a few more amps it would give it enough to start but when i did sparks came off the live side of my battery when i turned the key.

yes it is getting fuel but not sure on the spark.

i wet through once again and checked the connections and cleaned any corrosion off and made sure the grounds were good and still nothing.

Suggested Repair

While someone holds the key in start, lightly tap the starter housing. If the truck then cranks or starts, replace the starter because it is likely stuck. Recheck battery and cable connections after sparks appeared at the live battery terminal during a jump attempt.

Conversation Summary

The owner of a 1984 Ford F-150 with a 5.8L engine says it will not crank after replacing the battery, alternator, cables, solenoid, power steering pump, and starter. The solenoid buzzes and then stops, fuel is present, and spark has not been confirmed. The expert says the starter may be stuck and recommends tapping the starter housing while the key is held in start; if it starts, replace the starter.
