Question about 1989 Honda Civic

3 Answers

Won't start!!!!!! Fuel pump works, engine turns over. Somtimes it will start, but most time it won't. Pump in tank is pushing fuel through the system. Seems like the fuel is not getting injected into intake. When it does start it will run for 8-10 sec'ds then quit, just like you shut off key. There isn't any interuption in ignition power. Thank you in advance G.O.

    Yes, I have the exact same problem. The engine turns over - I can even get it to rev up, but it just dies after I rev it. I am very eager to hear what a solution to this would be.


    thanks

Replace the Main Relay?

Strtrcr4life: I had a similar problem where I had fuel, spark, compression etc... Everything as it should be. Turned out I had a weak (cracked) coil. I could see a spark if the plugs were taken out of the piston, but when they were in the piston, the high-density air & fuel mix was too difficult for the spark to jump. Hope this helps. JV

Start a Camry after it ran completely out of gas. Does the fuel pump fill the line when tank is filled & key turned?


Your fuel pump is located inside the gas tank and every time you turn on the ignition switch the fuel pump will start and pressurize the fuel line for a regular starting cycle. But, since your fuel lines are totally empty. I would turn on the ignition for a 20 second period. then turn it off for a few minutes to let the system fuel system reset and then turn the key back on for the same amount of time and do this for at least 4 times. Each time you turn on the key if you have waited long enough to allow the fuel system to reset. This will in the end fill the fuel lines and fuel rail on the engine and then you should be able to crank the engine and start ok. do not crank the engine until after you have cycled the ignition key about four times and wait about 2 minutes in-between cycles.
Have a nice day, regards, Dennis

Car won' start, battery is ok, antifreeze is low but not out could this be the problem?


No. it wouldn't keep it from starting. If the engine cranks but won't start, probably gas or spark (ignition) related. Do you hear the fuel pump in the tank turn on for a couple of seconds, when turning key to on, not start? If you cannot hear the pump, better check if you are getting gas up to the engine. Maybe the fuel pump quit, or the pump circuit needs looked at. The pump should briefly turn on with key on to pressurize the fuel system-the fuel line and the fuel rail where the injectors are. Then the pump will turn off, and only come back on again when the engine is cranking, and stay on when running.
Correct fuel pressure is important for easy starting, and good engine performance. Have the fuel pressure checked against the specification for your vehicle. If fuel pressure is good, check the ignition system-check for spark.

New fuel pump won't prime. No fuel from gas tank to engie. Lines are clear.


The pump works without priming anything. If the tank is vented, and you have fuel in the tank, and the pump is installed correctly, it should pump fuel out.
Are you sure the pump is getting power and ground ?

I have a 2002 holden rodeo 3ltr turbo diesel that just stopped while driving how do you check to see if it is the pump or just blocked lines


Just to start with the basics make sure their is fuel in it ... somtimes when these trucks run out of fuel you have to add more then 5 gallons to get the fuel high enough to run over the internal cup that the fuel pick up tube sets in 1 or 2 gallons is not enough to do this . Then have some one try starting the truck while you remove the fuel cap and put your ear to the fill tube for the gasoline you should be able to hear the fuel pump run because it is located inside the fuel tank . If you don't hear the pump running you can try hitting the bottom center of the fuel tank with a heavey blunt object ( block of wood ,Baseball bat ect.) nothing that has a sharp edge . Do this while some one is cranking ( turning the key to start the truck) this somtimes will free the pump up and it will start working again . If it starts then you know the pump is bad . Somtimes when the pump frees up they work again for weeks or months but it not good to take that chance and break down on the highway. Replace the pump and filter .

Engine turns over but wont start. 1997 gmc jimmy


Fuel Pump or starter. Since you say it's turning over but won't start I'd say it's your fuel pump. You'll probably have to drop your gas tank to fix this problem as your fuel pump is in the tank. You might be able to just loosen the straps and lower your tank a little to access it without removing the whole tank. Check around to local junk yards for this part and you'll probably find it for half the price as new. Make sure you can get your money back if the used pump doesn't work before you pay for it though. Don't forget to run fuel system cleaner (2 bottles to a full tank) once a month.

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.

Where is the fuel pump located in a 1985 fiero


from autozone.com:

The Fiero is equipped with a electric fuel pump and gauge sending unit mounted in the fuel tank. The pump is serviced and a complete unit by removing the fuel tank.
REMOVAL & INSTALLATION

CAUTION To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing any fuel system component. If this procedure is not performed, fuel may be sprayed out of the connection under pressure. Always keep a dry chemical (Class B) fire extinguisher near the work area.

  1. Disconnect the negative (-) battery cable.
  2. Relieve the fuel system pressure.

Remove the fuel pump fuse from the fuse block located in the passenger compartment. Start the engine and run until the engine stops due to the lack of fuel. Crank the engine for 3 seconds to ensure all pressure is relieved.
  1. Drain all the fuel from the tank using a suction pump.
  2. Raise the vehicle and support with jackstands.
  3. Disconnect the wiring from the tank.
  4. Remove the ground wire retaining screw from under the body.
  5. Disconnect all hoses and filler neck from the tank.
  6. Support the tank on a jack and remove the retaining strap nuts.
  7. Lower the tank enough to disconnect the fuel sending unit wires.
  8. Disconnect the fuel line, vapor line and return line.
  9. Remove the tank from the vehicle.
  10. Remove the fuel gauge/pump retaining ring by turning the cam lock ring counterclockwise using a spanner wrench such as tool J-24187.
  11. Remove the gauge unit and the pump.

To install:
  1. Inspect the fuel pump attaching hose for any signs of deterioration and replace if necessary. Also, check the rubber sound insulator at the bottom of the pump.
  2. Push the fuel pump assembly into the attaching hose.
  3. Using a new O-ring seal, install the pump assembly into the tank.
  4. Install the cam lock ring over the pump and lock by turning clockwise with a spanner wrench J-24187 or equivalent.
  5. Support the tank on a suitable jack.
  6. Raise the tank enough to connect all fuel and filler hoses.
  7. Connect all electrical wires to the pump and tank.
  8. Raise the tank and install the retaining strap nuts. Use new sound reducing pad if they are damaged. Check all connections and wire to ensure proper installation before refilling the tank.
  9. Refill the tank with unleaded fuel. Reconnect the negative (-) battery cable.
  10. Start the engine and check for fuel leaks and gauge operation.

Engine cranks well, half a tank of gas but won't start! Just cranks seems like gas not entering fuel system.


you may be correct, the first thing is to try starting fluid, spray in throttlebody and see if truck starts for a few seconds, if it does then its a fuel problem, mostly a bad fuelpump, start by doing this to see if it a fuel problem,then you can check all the fuses and check for power at pump,alot of times a bad pump will start by banging on bottom of tank while cranking engine if it starts then a bad pump for sure.
