Fuel Problem

[Slabjack]

Hi,
I have an 86 Ford F-150 that is dumping fuel in #8 cyclinder.
I replaced the EEC computer and still the problem is there,also replaced a burned wire leading to the computer still nothing.Replace two fuel injectors samething nothing.
Maybe someone could give me advice on what is wrong.
Oh I should mention the truck turns over but won`t start.

Thank you

what do you mean by dumping fuel. is the plug not firing or the injector not pulsing

Well when I try to start the truck up,it will turn over (not start) I do get a good spark. then it binds up after a couple of turns.
When I removed the spark plug the cyclinder it is full of gas.
I am not sure if the injector is pulsing or not

How do you check it(I am no mechanic).
Thanks for the reply

have you changed spark plugs? you may have some internal damage. bent valve or something. do a compression check.

I will try changing the plugs & also do a compression check.
It could be internal there is 300,000 miles on the truck.

Thanks for the advice mustangmike351c.
