Wont Start

[351FORD]

i have a 1985 f 150 with a 351 clevand and it wont start. i have changed the coil and the brain but i still cant get it to start. there have been problems with the coil before but the one on there is brand new. i i turn it over a lot it will finally start a little and then i have to pump the gas. please help.

It starts with basics------if its got fuel/spark/and its in time, it'll start.

i have talked to people and they said cause the cold weather i might need to check the timing. what do you think

 

[blacksnapon]

If the timing was off, it wouldn't make a difference cold or hot. I would lean toward choke or fuel delivery.

well the last time i had the timing checked it was off 20 degrees. it ran fine until the other day when i need it. it started then i drove it a little bit. i parked and didnt shut it off but it died. i think it might be the timing tho.

if its high mileage, you might have a worn timing chain.

i bought the truck a while back and the milage says its got around 400 000 to 500 000 its def. not the same motor but how could you tell its the timing chain

 

[351FORD]

the bad thing is is that i dont no how many miles are on that motor. if you can figure out what the cause is i would greatly appreciate

 

[blacksnapon]

pull #1 spark plug, put your finger over the hole,and have someone crank the motor. Immediately, when the compression blows your finger off the hole, stop cranking. The #1 cylinder should be at tdc. see if the timing mark lines up. If you dont have compression, I would suspect a chain.

i have sucessfully started my truck and it dies every now and then. but i think i might have a little bit of condesation or water in my tank from sitting. i am going to try to put some heet in it and some fresh gas cause it will fire with ether. so i will try that and see. thanks for all of the help i appreciate it greatly.
