2003 Chevy Tahoe died on freeway! HElP!

[Slammedchevy01]

Left for work this AM, seemed funny when I left the driveway....figured GREAT, tranny is probably slipping. Seemed to be from standstill, then a little more on freeway. Went to turn off exit to head back home and completely died. Lost power steering and luckily made it to shoulder.

It wouldn't crank then turned over and died, I was thinking alternator but tow tech said may be fuel pump too. I know they are known for the good ol' fuel pump. I would think if fuel pump it would turn over and sputter then die yea?

Volts seemed good on dash prior, battery tested marginal at last oil change too. It has 125k on the clock.....

With the key on, try using a rubber or plastic mallet and bang on your gas tank a few times (from under the truck). Try to start it. If that doesn't work, have someone bang on it while you're cranking the engine. Sometimes a bad fuel pump can be jolted into working again to get you to a place where you can replace the pump.

I'm at home now, got a AAA tow. Might start with alternator

Normally when a fuel pump dies it's not while driving, but anything can happen I suppose.

It didn't sputter at all either which I would expect with lack of fuel

I was pulling a U-Haul with my 98 Blazer across the desert in Utah when my fuel pump crapped out. Luckily my wife was behind me in our other car. However we were 30 miles from the nearest town. Lol..well not really.
Trust nothing mechanical.

Had the same exact situation happen to me. I was driving, vehicle turned off while i was driving. It wouldnt turn over at all. So i called a tow truck company after banging on the tank and trying to start it. No go! I replaced the fuel pump, started right up, never had an issue after that. $375 bill, but i would rather have that happen to me near home, which it did.

375 is cheap!

Well I don't hear a "whine" like I do when o turn on my 2001 Silverado ignition so may be pump. Going to give the tank a few whacks lol

So how'd you make out? Was it the pump?

 

[Slammedchevy01]

No dice on the mallet to tank

Hopefully it's something as simple as a battery or an alternator. Just changed both of mine last month.

if the alternator crapped out you would of had a battery light pop on. Did you notice anything like that? Also when your alternator dies, Your truck is running only on battery power and since there is not power coming from the alternator, when its depleted, it be like having a dead battery, no or hardly any power at all. If you have enough to crank i doubt its an alternator

for ***** n giggles you can stick some brake clean with a straw into your TB and give it a few shots. Starts up or tries to, its definatly a pump

 

[Slammedchevy01]

Multimeter test key off 12.-12.6, key on 12.3-4 start up 10 (one time dropped to 6v) then 14.5
