Well one of the things we all dread finally happened to me this evening. And of course it had to wait till it was freezing cold and wind blowing 40 mph. I went into Food Lion to get a drink to take to my friends house and came out to leave and it wouldn't start. It turned over, but died right away. I tried to crank it again and thats when I noticed the fuel pump didn't come on. Checked the fuse, it was fine, switched around some relays when my friend got there but neither one of us knew which was the fuel pump relay. So the car is sitting in the parking lot and I have no way to get to college which is a 50 mile round trip every day. I've heard its a b!tch to change so I don't want to tackle this at the house. I know you gotta take down the axle and exhaust and drop the tank So I guess it'll have to go to the shop. How much should I expect to pay for them to do the job? I gotta have my car back ASAP. Its one thing after another with this damn car. I just got it out of the shop a month ago When I get it back this time I'll have to worry about the tranny b/c its acting up too

 

IT HURTS
IT HURTS BIG TIME.
I had help with parts, BUT
Ya gotta get every part for the long run of fuel pump life.
I got new pump, inline regulator, new fuel sock, new fuel injection hose, too.
It took me and a friend 3-4 hours to do the job, in air, on lift.
Very sorry to hear.
Very sorry.
Been there.
Mine died during my home move.
Best thoughts to ya.

 

You were LUCKY you had a lift. I had jack stands and alot of elbow grease to get the damn tank out!(at least it was empty though ). Took me by myself almost 1 1/2 DAYS! working for around 2 hours on/off cause I would get pissed and start forcing things that did not like to be forced. I still have not put all the suspension back on the 91 yet and this was last summer I did this!. I put the LCA's, the springs and thats it actually. DAMN I need to get that car back into the air!. LOL

 

I also vote for doing it yourself... the pump itself is only $100, you'll pay another $300 for labor. A word of advice- the regular hoses (charcoal vent canister, tank vent, fuel return hose) are non-pressure, and you can find them anywhere (common fuel line). The fuel feed hose is pressurized, comes with special fittings, and will need to be special ordered from GM. Don't expect to have it the day before the swap... I haven't replaced mine yet (didn't think of it the first time I replaced the pump, thought of it too late when I replaced the second pump), and it's still alright, but man, it looks really cracked.

 

Or you could do what the person who owned my car before me did. Cut the floor right above the tank.

 

Just a quick FYI for anyone that hasn't had the pump die yet... The fuel pump relay won't cause a problem if it goes bad. The FI cars are engineered so if the fuel pump relay dies, and the engine has oil pressure the power to the fuel pump is rerouted bypassing the fuel pump relay. Subsequently, when the fuel pump relay goes bad the car takes about 3 cranks to start instead of 1.

 

I paid about $45 for the pump and another 300 to have it installed at Pep Boys. Much better than the ungodly amount the dealer wanted (600 total ). If saving money is most important -- it can be done. I chose to avoid the aggravation and had someone else take care of it. Did you check the fuel pressure?

 

Here are the AC part numbers of the stuff I got.
And the previous owner had someone else do this job before.
I saw "their" work when I had the stuff in my hands.
ACD EP240 (GM# 25116162) Pump
ACD TS4 (25055458) Strainer
ACD FP27 (25094266) Fuel Pulsator
ACD GF481 (25055052) Filter

Even tho I had a lift & help, it is a lousy job.
Best thoughts to ya.
My Fuel Injection hose for this project cost me a $1.
I have to disagree with Tom on that one detail.
I had a VERY BAD experience using common gas hose & FI Pumps.
The hose constricted under pump pressure only allowing me to go 35MPH max.
AND it wasn't necessary (ON MY CAR) to obtain the metal hose Tom speaks of.
Yours may be different.
AND IF YOU PLAN ON KEEPING YOUR RIDE ALONG TIME, do it right. I like my car, hopefully for atleast 11 years..

 

I paid 25 bucks for my New pump. 3 bucks on the sock, and another 3 on F/I fuel hose.

Who every pays $100 for the pump alone is paying way too much IMO. You can convert to an out of tank pump for less!.

(and I DID cut a hole in the rear shelf to make subsequent changes ALOT easier)

 

Hey Karl,

I forgot to ask you........did you have to use the dampner/pulsator I gave you? I ask because some cars use them and others don't. Usually we'll get them and if we don't need it we'll send it back.

 

BIG YES ON THAT ONE!
I replaced everything I could AND SHOULD.
What I pulled out was scary looking.
The "in my car" fuel sock was BLACK!
The hard line had wires soldered to it.
I replaced everything I could.
And even the external "soft" fuel lines, too. W/Fuel Injection hose.

Previous mechanics are wonderous creatures.
Known as "Bubba"

FYI Fuel injection gas line is much tougher than regular fuel line.
When ya get the two types of gas line hose in your hand, you'll know instantly.

 

I don't know if you guys remember, but there's a warning against using the pulsator. Since the pulsator only attaches to the fuel lines with thick o-rings, the o-rings can deteriorate, and leak, and you lose fuel pressure. So NEVER re-use a pulsator! You can do what I did (and what the TPI guys have also done), and replace the pulsator with a short length of fuel injection hose (regular low-pressure hose like for the tank vent lines won't be good here) and some hose clamps.
