After driving for approx 1 hr and a half and I stop my SUV, (turn off the engine), It takes me about half an hour before it will start again.

It is a 1994 Chevrolet S-10 Blazer

Do you know what the problem might be??????

I have a 1998 chevy silverado with a 350 in it. Its a 2wd truck. When I try starting it in the morning it takes about 8 to 10 trys. Once its runing its good to go. But when ever its cold its hard to start. The truck has a new fuelpump,plugs,wires,pcv valve, I put a waterpump on it last year but last winter my heat did not work well. I flushed the system put a new thermostat also but it smeled like it was running hot when it was not oh i put a heatercore in 2 years ago. the truck has 80.ooo on the clock... whatch think.

Hi, my 98 Blazer died shortly after refilling an empty gas tank. My first thought was blocked fuel filter but after replacing filter still won't start. I hear the pump run for about 5 seconds then shut off and there is positive pressure at the engine side of fuel filter. (I got soaked with gas when I popped the fuel line off.) I'm guessing now that it may be the pressure regulator. Is there an easy way to check for this and is it a difficult job to change one out. Thanks M.H.

I have a 1996 Chevrolet S10 Blazer 4X4 & when it is cold the engine has to roll over several times to start. When it is warm it runs & starts fine. I have replaced coil, wires, plugs, fuel filter, rotor button & cap. Can anyone answer this question before I have to take it into the local Chevrolet Garage & spend a fortune!

Thanks Henry

I need help to locate the fuel line in my 2000 chevy Blazer

When I run my air conditioner for awhile my blazer starts to loose power and then it will shut off. Could this be the fuel pump or what do you think it is.

how to troubleshoot to find out if your fuel pump is bad. when i turn on the ignition I don't hear the fuel pump come on like it usually does. 99 chevy silerado 5.3

I have a 2001 silverado, I recently changed the plugs and wires, and the fuel filter. I then ran a diognostic on the computer and all systems checked out fine. When I try to start it it fires but wont stay running, regaurdless of triing to pump the gas pedal. I thought maybe it could be the fuel pump, if so what would be the easiest way to change that. If its not what else could it be. Thank you

Justin,

I just ran across your problem on the internet and I suppose you’ve fixed the problem by now. However, in case you didn’t, check the fuel pump regulator on the driver’s side on the fuel rail. That’s what‘s wrong with my 2000 Silverado. The diaphragm has a hole and is leaking fuel into the engine and causing flooding. It starts fine he first time in the morning but hard to start every time after. To get it started you need to press the accelerator a little less than half way and hold, then start the engine. That will open the throttle to allow more air to enter to get a better mix.

The proof is run the engine for a minute or so, shut off then pull off the vacuum line. If fuel is present at the vacuum port of the regulator then fuel is leaking into the manifold and causing flooding. The regulator is small but may run around $100.

hey i had similar problems to everyone else on here with my 96 blazer not wanting to start cold at all. usually took about 5 to 10 minutes of cranking but when warm fired up first turn. the fuel pressure regulators on those motors goes all the time about $70 for the part and not too hard to change. Good Luck.

I have a 94 Chevy Blazer with a vortec engine. I can get it started, but it dies after a short time. It has a new fuel pump. I checked all the fuel lines, fuel filter, fuses, all clear. It still won't stay running. And yes, it does have gas in it. Any ideas on what to do next?

My silverado died on the freeway. i noticed before it died as i was trying to pass someone that it just felt like it ran out of gas when the pedal got depressed, when i brought it back to where it was it ran fine. i tried to limp home and it started getting worse, to where i could only get around 1400 rpm out of it. came to a light died...had it towed it home, i get no noise out of the pump when key is on, is this normal? also i took out the fuel filter, then turned the key on, no fuel comes out at all, and no sound. it sounds to me like bad electric motor or electrical on the fuel pump, or the pump is siezed and mtor cant turn it. by the way the relay is fine. I should be getting fuel out of the fuel line when the filter is removed right? HELP

I have a 2000 chevy Blazer that I purchased a few months ago, since I have replaced the fuel Injector A.K.A "the spider also replaced the fuel tank pressure sensor..Since the day I did picked it up after shuttingt he engine off coolant comes out.It doesn't read hot. Now while I am driving it either dies but restarts or it bogs out while holding the gas down, but when you let off the gas it holds steady. I'm not sure what this is wether I need to replace the fuel pump or as simple as a fuel filter? Also could they have loosened something putting the gas tank back up due to putting the fuel tank sensor in???

the 20A Power Accy (relay?) heats up after moving the seats, clicks off then the door locks don't work. After cooling a bit everything comes back. But it will still heat up at the next driving of the Blazer.

Can anyone help? I have a 1992 Chevy S-10 Blazer V-6 TBI that over a 2 week period starting losing power when accelerating. Started out as a miss, but then got to be a bad miss. Then one day it started bogging down to the point it died. It appears to be flooding itself out. I have changed plugs, wires, distributor parts, checked the coil, checked for codes but does not read any, changed fuel pump and sending unit, changed the fuel regulator, what else is left?? I can see the injectors pumping fuel into the carb. If it sits and gas dries up, i can start it, but it will eventually die or if i give it any gas it dies automatically.. i know i am flooding it out, it acts as if the spark and gas mixture isnt timing right.. could it be out of time?? i tried to manually adjust timing but that didnt seem to work...any other ideas would be great..thanks

the problem is the catalytic converter

i removed mine and 92 blazer started and ran good

i just replaced it with a straight pipe

I personally would let it run for a while 1hr with open pipe to ensure the gas b/u and other is free and clear

it will give the engine time to breath and run free with out resistance

Hey Everybody !

This is larry

my Truck Died totaly after trying and trying to get it started.

I thought it was the Fuel Pump or the Ignition Modul or even the Coil.

The funny thing was that my warning lights on the Dash did not come on.

So i went and Checked the Ignition Swith.

and then i replaced it and the Truck runns Great now.

so i hope this info helps somebody else in the future.

HI All, I bought a 1998 Chevy Blazer and the radio had been removed. I have fuel pressure and I put a new ignition switch in it but it will start and run with no problems for about 3 seconds then die. I can't figure it out. has anyone had this problem? It has the delco II deturance theft system on it. Could this be what is wrong, how do I fix this. Any help would be greatly appriceated. thanks.

Help! I have a 1999 blazer and it will not start. I have replaced the fuel pump twice and fuel filter once. If I pour gas down through the throttle body it will start. both times I replaced the fuel pump it ran fine for a while then quit again. the fuel pump seems to be working fine now. I took it to local mechanic shop and they said it was the security system or the body control module and suggested that i send it to the chevy dealership. the chevy dealer said it was not the security system and that they wanted to drop the gas tank and check for kinked gas lines. then said if that was not the problem then it was the fuel pump and it would all cost about a thousand dollars. so I had it towed back to my house. I don't see how it could be the fuel pump again. does anyone know what could be the problem. Thanks

For those of you in this forum who have experienced a loss of power or hesitation with a 4.3 Vortec, I had a similar problem with my 2000 Blazer for a while until a mechanic thought of the mass airflow sensor. After a thorough cleaning, engine power was restored and I haven't had trouble since.

I have 95 blazer that is running rough, when i give it gas to accelerate it dies out trying to get revs up. There is a smell of gasoline. I changed the wires and plugs but when i'm driving it keeps cutting out like it'll stall then picks up revs again.
