Hey I have a 1992 f150 custom 302 5.0 v8 4x4 and it's having trouble starting after being run its not overheating in order to start I have to press the gas pedal to the floor while starting I have changed the fuel filter but I know very little about things like this and it fires right up when cold thanks for any help

 

Clean your grounds! Follow your growing cables from the battery to the from, and engine block un blot them and sand down to bare metal, make sure there's no rust paint or anything else between the two contact surfaces, my 91 bronco was the same way,went through 3starters before I did the cables! After the cables never had another problem!

 

Shoudust is right! But ive put on several bad O'reilly starters. I just replaced one that was bad pulling 350 amps!!! Bought a pro torque from summit for 200.

 

Should I replace the cables

 

Have you replaced the fuel pressure regulator? My 92 did the same thing, I had to hold the gas pedal down to the floor to start the truck once it was warm!

 

Only if the ends are severely corroded and you can't get them clean. Or they have insulation defects, other than that they should be all right,

 

Just replaced and beefed up my electrical, now the truck starts in about a second.

 

Does it slow crank? A warm starter pulls more energy and a hot battery has less to give. So check your cables and test the battery and starter to see what load it pulls. As far as flooring it goes, when you hold the throttle wide open and crank the computer turns off the fuel pump. You can't prime the engine on an injected engine so the only thing your doing is holding the air intake open and cutting off the fuel. This is only helpful if the engine is flooded. Which points back to the fuel regulator. Check for error codes.

 

Alright I have cleaned all my air intake, replaced the fuel filter, and traced two of my three ground and completely sanded them down and I'm still having the same problem what should be next step
