1994 Ranger 4.0l fuel pump died

[RonD]

So my fuel pump finally gave up after 30 years
Was on a job site as well, last job before long weekend, at 2pm was ready to leave and Crank but No Start
Couldn't hear the fuel pump with key on and off a few times
Did the OBD1 jumper and FP relay "clicked" but no pump sound
Jumped the FP relay, no sound from tank

OHMs tested FP relay's out to pump slot, 0.9-1.0 ohms, so inertia switch was OK but pump wasn't, tested inertia switch as well waiting for tow truck

Was 20miles from home, called some local shops in that area, $1,000-$1,500can$, and "maybe" they could get to it the end of next week
Have all my tools in the truck so got it towed home, $160can$, he didn't get to me until 5:30pm, didn't get to my place until 6:30

Ordered a new pump assembly, from my local parts store while waiting, they couldn't get Motorcraft, so I am getting Spectra..........can't just get the pump only either by Saturday(they are closed today)

This morning I got the tools out and canopy off, then bed liner out
6 bed bolts came out OK, tight but all 6 came out with breaker bar and T-55
3 7mm filler bolts
1 rear light connector

Bed is slid back and I hosed off the top of tank
Took a few hours

I will let it dry out a bit, before testing wires and pulling fuel lines, still raining off and on here

A little trick a mechanic told me about years ago and I have heard it having worked several times. If you would have gotten out and banged on the bottom of the tank, it might have taken off. Must be the pump gets so old the brushes in the motor are not making contact is the only reason I can think of that this trick works.

Yes, I did do that as well but have a skid plate under the tank, its a 4x4
I hit it from the sides and a bit on the bottom with jumper wire in place, so I could hear if it started, no joy
Had 3 hours and got very bored, lol

Did you try cursing at it?

 

[RonD]

Just tested wiring at tank connector, battery voltage with jumper in place

 

[RonD]

Spectra SP333H fuel pump assembly is in and working
The fuel line clips came out OK but new assembly came with new clips so used them, greased electrical connector

Sender on new assembly goes down to 14 ohms, tops out at 168 ohms, so should be good

Bed is back on, put anti-seize on the 6 bolts

20min highway drive went fine
