How long do fuel pumps last ?
My vet is a 1987 and used it about a week ago no problem. Went to start it the other day and it started just for a second and died. After that it would just crank but wouldn't fire up. I haven't had a chance to even check for fuel pressure. I replaced my fuel pump about 4 years ago and put less then 10 thousand miles on it. I was just interested to know if fuel pumps can die that quickly. Also i ran my car low on gas the last time i drove it ( reserve light came on) anyone ever have that fuel filter in gas line clog. I put some gas in it so it not out of gas thanks for any help

my experience
Hey, i am not a expert but.. Recently my 1987 did the same thing. I thought surely it is not the fuel pump since it was not very old at all.Well after checking everything other than the pump.. and even though I did not have fuel at the fuel rail.. I made a test jumper and tested the pump in the car. Well it was bad.. so i changed it and it runs great again.
I did take some advice that I received here and shot some starting fluid in the intake, well when it fired right up... then quit. I knew the issue was not ignition related. Gggg

I have gone through the same thing on my Suburban. First pump lasted 160,000 mi, then the replacement took a dirt nap less than two years/20,000 mi later. The replacement was aftermarket, not OE, so that may have made a difference.

I bought an Airtex pump for the Z that had a bad check valve, right out ot the box! Autozone replaced it, w/o a hitch. That was 5 years ago and still running (I hope).
Note: I don't have my 95 LT1 car anymore (
), but there is a (red) test lead poking out of the wire loom next to the diagnostic connector (on the ZR-1) specifically for testing the current draw of the fuel pumps. Can someone see if there is such a test wire (or the like) on standard C4s? If there is one, it would be very useful to do a quick evaluation of the pump's current draw (4-5 amperes w/ ignition switch OFF).

The fuel pump in my 94 is original and has been great. Only 105k on the odometer though so not a terrible amount of use in the last 20 years.
Seems that two years is about the norm for a major aftermarket electrical component. Replaced the Opti Spark unit on my 94 back in 2012 and just replaced it again last week. Got 3k miles out of it before it crapped out. Original unit lasted 101k miles.

Check the pressure.

I just replaced mine a few weeks ago too. I used the check fuses, starter fluid technique. Ordered a top tier pump from Rock Auto and replaced it in about an hour.
I like to blame ethanol for all my full related issues.
The car is garage kept and only run once a month. It has a brake issue I'm still trying to resolve before it goes back on the road again.

I would like to suggest to avoid after market fuel pump, I know OEM cost alot more, but I myself hate doing and paying for things twice. Somethings are alright after market but a electric fuel pump is not one of the thing IMO. I also try not to run my tank past 1/4, the fuel pumps only means of cooling is the fuel it sits in.

Depends on the brand. My buddy and I experienced Universal HP?? Master pumps fail within a week. just enough PSi to start not enough to drive. and no low Gas or any issue's in the fuel system. also had a Holley projection pump fail approx 1 year. I now remove the stock pumps from the tank. And use my Aeromotive pump. PS you do not need the check ball keeping pressure in your rails after turning off.

Ethanol is a brutal Compound. Possible conspiracy theory?? to wreak havoc on engines.

My 88 lasted 25 years at 125,000 miles. Pump was still working when I replaced it. Pump was getting "lazy". Was taking 15 seconds to fire up on the first key turn. If I primed the pump by engaging the ignition twice, car would fire up in less than 5 seconds.
