the whining noise is your engines alternator bearings
they are worn out , the alternator is close to failure
it is barely producing any voltage
( the battery light in the dash only indicates that the alternator is no longer generating any amperage )
Ok 1 did you buy a brand new pump. 2 did it come with a replacement wiring harness. 3 if either 1 of those answers are no go buy a brand new pump with harness. If yes to both you got a bad pump.
most time there will be signs of pump going bad. like loud whinning noises or hard start like having to spinn engine over for long time before actually starting did u experience any problems like that which made you pay for fuel pump
are you sure the noise is comming from pump and not the belt tension pulley right next to it ?
I use a wiffle ball bat with both end caps cut off (hollow tube) held to my ear to help localize noises on running engines I have even found tricky intake vac leaks with that trick
Check fuel pump pressure. sounds silly but my 1500 ram van did this 2 months . replaced a lot of parts then left me sitting on side the road. Cause was fuel filter and pump.
