That is the problem i am chasing. The truck will not start. i cant warm it up and drive it if it wont start.

 

I should have started from the top of the thread.....doh!

Those IAT/ACT and ECT codes are probably invalid since you cannot start the truck. It would be advisable to check those sensors using a meter just to verify.

 

So,would any of these codes keep it from starting? I am at a loss with this thing lol. I cant get it to even try to start to get any more codes. Any more things you guys would advise to check??

 

Did you pull thè plugs to see if they were wet from gas? Did you check for bad vacuum hoses? Did you clean the TB? Did you pull the IAC and the seat area?

 

Unplug the ECT sensor and see if it starts.

 

I did unplug the ECT and tried to start,no go. I will the pull the plugs again and look. will go over all vacuum lines. I will also remove the idle air control and clean that and the throttle body. What do you mean by the seat area? Thanks guys I know we can make this old girl run again!!

 

Where you unbolt the iac clean out where the plunger sits.
Another thing you can try if all other things are fine is to spray around the manifold edges with wd40 while trying to start it. The way im thinking is if you have fuel in the cylinders and you have spark maybe you're sucking air through the intake gaskets or bad vacuum
line somewhere. Maybe others have other thoughts.

 

There was a guy with a 460 on here a few years back with the same problem and it turned out to be that all of the fuel injectors were plugged.

 

I checked to see if the plugs were wet and they are bone dry. Checked for vac leaks couldn't find anything right off. This weekend I'm gonna pull the fuel rail and injectors and turn It over and see if they are spraying. Gotta start somewhere with getting her running

 

Well a little update. I pulled the fuel rail and injectors today. 1 and 8 were the only injectors to spray fuel. Guess sitting for 6 years froze them up? Looks like a set of new ones.

 

You could try to put air pressure on them from reverse side then soak them in some PB Blaster or Kroil oil over night. they might just have a small plug in them, it doesn't mean they're bad.

 

An update for those of you that helped. Today I got my new injectors. I got them in and she fired right up. I could not get the old ones freed up.

 

Glad to hear you got it running

 

Glad to hear you got her going! These old 460's sound beautiful... now about those pics i was asking for earlier...

 

I am happy you got your 7.5 started up! I wanted to advise you to pickup a spare distributor, to keep in the truck, as the PIP sensors in the TFI distributors will fail and most aftermarket ones will fail quickly. I found 2 new Motorcraft sensors and replaced the one in my aftermarket distributor that had failed, and keep it behind the back seat of my crew cab. Last time it failed, I pulled the distributor and dropped in my good spare and lit it right up, and away I went. I usually keep a Ford distributor wrench, timing light, and a piece of yellow tire marker crayon in truck as well. Happy motoring! Dale
