Question about 2000 Chevrolet Blazer

1 Answer

Won't start I put a new fuel pump in and now it won't start. It was having trouble before this also. Sometimes it would start and other times it won't. The engine turns over though. I'm thinking it might be a bad relay or connection, but I don't know where to start.

Hi,

Firstly,
As you say the engine turns over so the battery is ok.

So, the problem should be either electrical (wiring-electronic ignition unit), or carb disfunction.

But before checking the above,
1) start by checking and replacing or cleaning if necesary air filter.
2) replace spark-plug


Then ,
check and clean the electrical system's wiring, and if possible for you remove the electronic ignition unit and carefully clean its plugs.

Finally,
Remove the carburater and clean it carefully using gasoline.
Be sure you keep it away from any dust or dirt.

Try these things there are on the top reasons for such problems.
Hope it works out, looking forward to providing further assistance!

Motor turns over won't start. Cleaned terminals, put in new battery, still won't start. Removed gas cap to vent air on hot day, still won't start. Lights all come on, all electrics appear to...


Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they get loud or stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.

It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.

If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.

Dear Fixya, My 1993 excel hyundai turns over but won't start, we put plugs and wires and new fuel gasket. we r wondering where the fuel pump is, is there one or two pumps and how to get to them to fix...


Have you checked for spark first? Sometimes a car won't start due to no spark. This condition is usually caused by: Security system, bad ignition module, crankshaft sensor, camshaft sensor. You check it by pulling a plug wire and putting a screwdriver in the wire to see if it arcs. If it is getting fire look for the fuel pressure release valve usually located on the fuel rail, looks like a tire valve stem. If it shoots out gas, and you hear the fuel pump prime, check the fuel pressure regulator. It could also be the timing. There are four things needed for a car to start: fuel, spark, timing, compression. As for your question, as far as I know there is one fuel pump, you have to drop the tank to fix it. Hope this helps.

On first crank fuel pump doesnt hold pressure and has to be cranked on for several seconds


sounds like its not working properly, the fuel pump pumps or it does't, then goes to regulator this is where pressure is adjusted. check fuel pressure with gauge, sometimes even new fuel pumps don't pump enough fuel. most fuel injected cars have over 50 pounds pressure.

I have a 1994 Volvo 940 Turbo. Just lately it has been hard to start. It will crank but won't fire. Sometimes it fires but won't stay running. At first it was doing this only when the engine was warm, but...


Spray some gum out in air flow sensor and see if it starts up.
If it does you need a new fuel pump. To confirm look for schrater valve on fuel rail, put a rag around it and wear eye protection. Push valve and see if fuel shots out while the vehicle IS NOT RUNNING. I fuel does not shoot out you have no residual pressure and need a new pump.
The other thing is to place key in ignition and put it to on position you shoulsd hear a buzzing sound from pump.

Have trouble starting car from time to time


MAYBE YOUR FUEL LINE AND FUEL FILTER, SOUNDS LIKE THE GASOLINE WON’T GO THROUGH, YOU CAN START THE CAR, PUT IT INTO PARK AND PUSH THE GAS PADAL SEVERAL TIMES, SOMETIMES PUSH THE DIRT OUT, OTHERWISE PROBABLY YOU HAVE TO CHANGE THE FUEL FILTER. TRY IT.
