I have a 1994 5.0 F150 and a few days ago I started it up and after about 3 seconds the idle dropped down to about 500 then it cut off from low idle of course. When I put it in gear it tries to drop down but not too bad because I keep hitting the gas, but after it warms up it runs perfectly fine then I cut it off and start it back up and it idles fine in park and while in gear. A few weeks ago I had a problem where I had to turn the key on and off 2 times so the fuel pump sent fuel twice. Then it would start and run fine. That problem randomly went away but do y'all think this new problem is the same thing just worse?I was thinking fuel pump or fuel pressure regulator? Maybe it has something to do with intake? Plugs? I have no idea but thanks in advance.

 

Hey
Check your temp sending unit for FI.
Right front of intake manifold.

 

What does it look like and how do I test it?

 

Let me try and remember...
Apx. 1/2" around and 3" long...
It's kinda hidden down there.
I'm sure the only way you will see it is from directly above.
I don't know how to test it.
But they are not expensive.

 

Alright I will look into that. Do you know how that could be causing my problem? Just wondering. Also, the needle for my oil pressure guage reads between the N and O of NORMAL at startup and then probably moves to the middle of the O after its warmed up. Is that normal or is it too low?
