Hung Like a Stang

Not necessarily true. Holding the pedal to the floor on most fuel injected vehilces puts the vehicle in clear-flood mode, lowering a:f ratio to about 18:1. Thus, probelms could be in fuel return blockage, bad fuel pressure/bad fuel pressure regulator.

well i will definatly check all my connections to the coil and all the wires.

But when i do my noid light test and it fail ie not lighting up(am i right?) what exactly is that telling me?

STOP

PLEASE, don't do this to yourself.

When I service the SN, I often find:

Remove the distributor, check the inside and outside for black carbon.crud, and the shaft for wobble/play.
It really sounds like you have bad bearings in the dizzy, or a failed dizzy and pickup.

Usually if your lucky, you might get a "squeak " sound from it.

2. BAD IDLE AIR CONTROL VALVE, WILL CAUSE THIS AS WELL, it ay be dirty, or have electrically failed.

3. A dirty MAF and or Mis clocked(not at 12*= straight up and even position) will do this.


Your next bet is FORD, this issue will be intermittent then become a complete - NO START NO RUN SHORTLY.

This is a issue you don't want to get too involved in over the net, and a Ford TECH will find it fast in the shop, through our OASIS System, VERY WORTH THE DIAGNOSIS FEE.

FORD TOUGH

I knew some one would say that but putting the pedal to the floor is not really pumping.

FORD TOUGH

I thought you said you did not have spark?

Thanks those are all great ideas
my dizzy does squeak and if ya push it just a little bit it goes away.
The IAC if that was bad wouldnt i have running issues too?
How would i be able to adjust the MAF?
I brought it to ford and they couldnt do anything or find anything because they couldnt get it to do it.

Ford Tough
I do have spark i just have noticed that sometimes i dont so basically i have intermittent spark lol.
And the reason for the noid light is because i know i have fuel at the pressure relif valve but maybe the injectors are not shooting.
