Issue while driving home.

[Spicycook]

Did some driving today(drove an hour and a half sat for two and drove for an hour and a half) in my 94 explorer, and didn't have any issues. Made it home and a couple hours later went to the store for some coffee. On the way back I stopped to fuel up. Then when I'm almost home, my charge idiot light comes on, I lose power steering and my radiator over flow is boiling over. I was able to coast into the driveway.


Temp gauge didn't read hot at all today.

I figured I'd let it cool then take a look in the morning. but if anyone can give me an idea where to start at I'd appreciate it.


Edit: I'm thinking serpentine belt at this time.

 

[Spicycook]

Not the belt, but the belt tensioner pulley.

 

[Dano!]

Might as well replace the thermostat while your in there.

Check the belt for damage too. If it slipping, there could be friction damage.

Or the engine died---better consider that one-

Edit,
By
"died" I meant "quit running"

Hot supper = cracked heads (often). Hope it didn't get too hot...

 

[Spicycook]

Belt looked fine no damage at all. I did nick the hose next to the pulley though, been trying to find the correct name for it so I can replace it.

As for cracked heads I don't think so. I'm not getting any of the typical sings after first test fire.

However I did notice a rougher start, but I think that is more related to the hole in the hose. but i won't know for sure till i replace it.

 

[Spicycook]

At this time that appears to be what was causing the majority of my rougher than normal start. made a temp patch out of duct tap to give it a start up test. worked well. i'll let it sit for a while longer let the engine get nice and cool then attempt the test again.

 

[Spicycook]

Nope still a rough idle. When I turn the key I hear the fuel pump engage, starts fine hits 1200 then bottoms out to 600. Sputters then dies. One thing that seems odd is when I hit the gas trying to rev it the rpms actually drop. Then when I let of the gas it revs momentarily then drops again.

Sounds like a fuel related issue to me

Check the fuel pump relay in the power distribution box under the hood on the passenger side. It could be working well enough to start the engine but run normally. Pretty soon it will quit all together. You can temporarily use the WOT relay until you get a new Ford relay. Don't bother with aftermarket.

Lookin at that pic again I see the Radiator hose is above the place you circled.
Are you sure that nick is in a hose and not a wire bundle?

Sawped it with the wot relay, no change in performance.

Yep looks to be just a hose to the air intake.

Took a look at it this morning, double checked to make sure no wires were nicked, loose or disconnected. No CIL either.

 

[Spicycook]

I have no clue what could be causing it at this point. I guess its time for randome spot checks.

Have you tried running the codes you might have a code that was thrown that's not lighting up the light now.

Search the forum for Checking Codes. It's real simple all you need is pen and paper and a piece of wire.

 

[Spicycook]

Didn't know how to do that.

codes I got were.

121
(O,R,M)
Throttle Position (TP) sensor out of range - TPS


539
(O)
System shows voltage at PCM pin 10 Is A/C on ?
**(A/c was on)**

543
(O)
Fuel pump monitor circuit shows no power - Power / Fuel Pump Circuits

121-Could be causing some of the problem but I think 543-is the main problem.
I'd start with checking the fuses and the inertia switch and go from there.

 

[Spicycook]

Checked the fuses and the switch, everything seems good. I'm hoping it's the fuel pressure regulator.
