#449 of 497 Bad Gas Mileage after replacing fuel pump
Dec 25, 2011 (3:51 pm)
I have a 2002 Chevy blazer with about 215,000 miles on it. My fuel pump gave out ( I've had no other problems with my blazer before this, it ran just beautifully) recently and I had it replaced. After getting it back from my mechanic I noticed I was getting half of the gas mileage I used to get. I took it back and my mechanic changed my spark plugs. I picked up my car and drove it home. The next time I went to start my car it would not start. I had it towed to the firestone down the street, and had to change my Dist cap and rotary back. My car started up just fine, strong as ever. I'm still getting this horrible gas mileage, any ideas on what it could possibly be?
#450 of 497 2003 Chevy Blazer Hot Soak Issues
Dec 31, 2011 (8:51 am)
I have 2003 Chevy Blazer with 56,000 miles on it. When I start it to run an errand and drive it for less than a half hour - run in and come out after 20-30 minutes it will not kick in. Have to wait a few minutes and give it a few tries and finally starts. Replaced the fuel pump over a year and a half ago. The mechanic cannot figure this out. This has been in the shop 3 times for this issues.
Note: This only happens in the Winter when the temp is 32 degrees or below. Once the weather warms up no issues...........I can count on this starting every December for the past 3 years!

Sounds like a bad connection or wire that has moisture freezing on it (on a bad spot or bad/loose connection and the freezing moisture expands causing a loss of connection) and messing up your connection until the moisture unfreezes which allows for connection again.

At that many miles, I'd have to tell you to start saving up for a down payment. I'm not being a smart alec, I just don't know too many GM's, Fords or dodge that are worth anything afte 200k miles.
Some people might have these that made it past 200k, like you, but believe me, it's an oddity.
But do look into a Toyota for a small 4 or 6 cylinder.
Ford F-250 or 350 for a full size truck.
Research and see for yourself how many toyota's are reaching 300k at 400k miles.
A small for, GM or dodge reaching 300k? Just doesn't happen.

Did you ever find a solution for this? Because my 2001 Jimmy is having similar problems

No had some work done and had fuel filter replaced. Runs better, for now. The real test is hot weather, that is when the stalling was at its worst.

I was told by an authorized dealer, the fuel pump doesn't send codes.
Now remember this part:
I went to all the parts sellers, Checker, Autozone, and none of them knew this. They just kept saying, "Sounds like blah blah blah...." And of course, I bought about 400 bucks worth of parts. Some even said the engine crank sensor. If it was the engine crack sensor, that would send a code. So don't let them bullshit you. Take it straight to a dealer.
Mine was fixed, it was the fuel pump and now I'm back in business.
Also another tip. I had them put in the exact brand name fuel pump.
Best Part: LifeTime Warranty, and guaranteed because a profesional authorized shop installed it.
If it ever goes out on me again, I get a new one FOR FREE!!!
My Blazer 4.3 ZR2 would start fine, then after about 10 minutes, begin to sputter or just cut out completely.
It finally died. After 6 months of sitting in the driveway, I threw in a new battery, it cranked and started enough for me to move it.
I let it idle, then it died, never to start again.
The dealer sent a tow truck, they took it, I got it back with a new fuel pump and I'm back in business!
Don't waste your time on parts store. Have a dealer pick it up and fix it.
But also have about a grand for this. The pump on my 2002 ZR2 was $420.00.
I hope this helps!
