It ran fine parked it now it wont start. Ichecked all the fuses nothing wrong there. Fuel bowl fills up no problem. I am not getting anycheck engine lights.its like its not getting any feul no smoke of any kind. i took a fuel line of the Fuel Pressure Regulator and had my wife crank the motor feul came out but i can my finger over the hole and easily stop the fuel?

Is the tachometer moving?

In the engine compartment look at the big 30 amp MAXI fuse in # 22 slot
1996 Bronco/F-Series

If blown the fuel heater shorted out check the MAXI fuse and let us know.
If you just replace the fuse it will blow again untill the fuel heater is unplugged

no the tachometer is not moving.

 

[TCruzan]

Most likely the Cam Postioning Sensor (CPS).

excavator,,,,,what is the story on getting your truck to run when you bot it as a non running truck...or do you have the story in a web page somewhere?

 

[ammayernick]

No tach is usually the CPS

 

[Jeep1947]

Autozone has CPS for $25.00 buy 2 and keep one in the glovecompartment with tools to change. On the fuel line was it the line to engine or the return line. Don't think you could hold the pressure with your finger if lift pump was pumping correctly.

 

[satzcollett]

yes it was the line to the engine. just put a new cps on it still no fire.

Can you...

Check the fuel pressure? At least 20 PSI?

Does the HPOP have oil in the reservoir?

Unplug the ICP and try?

Still thinking here.

what is the icp?
dont have the right allen wrench for the HPOP but ill get one tommorw. can i use a regular tire gauge and do i use it while it is cranking? i am still not getting any tach.

 

[okney1lz]

Umm...

Yes, tire gauge while cranking. Can be messy. Be careful.

ICP located near front of engine. Should have R & Y/R wire going to it.

See this: Fuel heater connection 2 pictures from friends & fun photos on webshots

No other wires look bare, burnt, or chaffed etc?

Batteries fully charged, cranking strong? Oil level ok?

 

[okney1lz]

Oh just to double check....

As Excavator suggested you did verify the condition of the fuses in the engine compartment box, right?

 

[satzcollett]

used a tire gauge to check the fuel pressure no pressure at all. checked the fuses again no bad ones.

 

[samduket]

any progress on this satz? might have a similar bug going on. did you stall out or just refuse to start up?

 

[satzcollett]

it was running fine then i parked now it wont start. changed the cps no help. i wasnt geting any feul pressure and noticed fuel around the pump so i changed it out still no help. going on 2 weeks still not starting. i checked out all the fuses several times still no help.

 

[tcgrmt]

I had a no start problem that would come and go. Ended up being the seal on the fire wall for the PCM was leaking water dwon into the PCM. Not enough for a water spot in the truck but enough to corrode the inside of the PCM. Just pulling the PCM wiring harness conector isn't enough, need to get the PCM to check.

With a mechanical fuel pump, as long as the cam is turning, the lines are clear, the filter is not plugged, the sock is not plugged and there are no leaks the fuel system and the pump works, you should be getting fuel. The PCM does not control fuel pressure in the early 7.3's. Is there fuel in both tanks? Try switching tanks. If you just replaced the pump, it will take allot of cranking to get the new one primed. Are you getting any fuel at the filter? Are you sure your pressure tester is good?

 

[97smoker4x4]

Are you testing fuel pressure while cranking? The engine must be turning over in order to build pressure in a mechanical fuel pump
