Car Cranks But Won't Start "No Fuel Pump Sound"

Car Cranks But Won't Start

If you find yourself in this situation, often times it can be a simple fix. The first thing you want to do is listen for the fuel pump when you turn the key to the on position. The fuel pump should make a humming noise when it is priming. If you do not hear this sound, then this most likely is your problem. Continue to follow this "Car Cranks But Won't Start No Fuel Pump Sound Guide" to troubleshoot your issue.

Checking The Fuse Box First

The first thing you are going to want to do is check the fuse box. It's very simple, it's located underneath the engine bay Hood. With this example the fuse box is positioned by the battery on the passenger side and it is a 7.5 amp fuse. Check this guide to verify if you have a good fuse or a bad fuse.

Now for most vehicles the main relay varies in it's location. The majority of the main relays are located underneath the driver side dash towards the left, and also behind the passenger side glove box to the right. This particular vehicle which happens to be a 1998 Honda Civic coupe, the main relay is located behind the glove box to the right. Honda civics 92-95 are located underneath the driver side dash to the left. Honda Civic's 96-00 are located on the passenger side behind the glove box to the right.

Locating The Main Relay

 Removing The Main Relay

Pulling the main relay is simple in this scenario. You simply press in on the glove box sides firmly and then pull the glove box towards you. This will allow the rubber bumpers to move past the stopping frame. Now that you have access, look to the right and you should see your main relay. The next step you will need to open the passenger side door and get access to the side panel, remove the phillips screw and pull firmly to pop the clips off the side panel. Now you can see that there is a 10mm bolt, remove the bolt and pull the main relay off the dash frame. Next push on the electrical clip to remove the plug from the main relay.

Repairing The Main Relay

To repair the main relay you need to remove the casing over it. Simply put a flat head screwdriver over either side and push out as you pull up. The internals of the main relay will slide out. What you will need for this job is a soldering kit and some flux flux. You can remove the white plastic plug clip from the relay so it won't overheat and melt. Next you're going to add some flux to the back solder joints. You can see in this image how the solder joint is cracked. This is what you will be looking for. Once you've added the flux you can take your soldering iron once it's up to temperature, hold it on the joint, and then add in some solder to repair each solder joint. When you're finished, clean it off with rubbing alcohol and a toothbrush and dry it off. Next place the main relay internals back in the casing and slip over the white plastic connector clip and push firmly until the black casing clips back in.
