One of the wires is for the gauge sender. You can check for voltage at the ends of the wires using a test light. There should be voltage there briefly (one second or so) when you first turn on the ignition. You need to get the polarity of the pump wires correct, so you might have to try both ways and see which way it pumps fuel. Was there not an electrical connector on the tank? You could also find a wiring diagram and determine which wire is which by color, and then check the connector pin digram to determine which color wire goes to which pin.

It is getting spark but it seems that there is no fuel pressure at the stem on the fuel line.how can I be sure it is the fule pump and not the relay or anything else. I have checked the fuses.


Hook up a fuel pressure gauge ! Go on youtube and watch videos on fuel pump electrical circuit testing ! Do you know how to use a DVOM - digital volt ohm meter . Find a wiring diagram at www.bbbind.com . Look at diagram to see what controls the fuel pump , relay , a control module etc.... If there is a relay ,pull it out an try to jump fuel pump directly .

If you have a vehicle that will turn over and over but will not start, I will tell you some things that you need to check. Every vehicle needs air, fuel, and fire to start. Now, the first thing you want to check is the fuel system. You want to make sure that the engine is getting fuel. The easiest way to test the fuel system is by testing the fuel pressure on the fuel rail. You need to refer to your owner manual for the correct measurement of pressure. Another easy test is using starter fluid. If it starts when you spray the fluid, you have a fuel issue. If it doesn't, check the ignition system. If your pressure is not correct or you have no way of testing the fuel pressure, start by checking your fuel pump. The fuel pump pumps fuel out of the gas tank and to your fuel filter. When you first turn your key on, you should be able to hear the fuel pump kick on for a second or two. It makes a soft buzzing sound. Listen for this sound. This will determine if the pump is kicking on and working. If you don't hear this sound, check your fuel pump fuse, relay, and your reset button. Not all vehicles have a reset button, so once again check to see if you have this button. If you change all of these and the pump still doesn't work, you may have a bad fuel pump. Test and make sure the pump is getting power before you change it. Now, you want to make sure the fuel filter is not stopped up. Check the gas lines and make sure they have no damage. Lastly, make sure fuel is getting to the fuel injectors. If you are getting fuel, you will need to make sure you are getting fire. You need to test your spark plugs or coils for spark. If you have spark, you should look over your timing belt or timing chain to make sure it is not broken or slipping. If you are not getting spark, you will need to check the spark plugs, coils, coil packs, wires, distributor, distributor cap, and rotor. Anyone of these can cause a vehicle to not spark. Check everything you can. Make sure the rotor is spinning and make sure the distributor cap has all metal contacts. Also, make sure the cap is not damaged or cracked. Make sure none of the plug/coil wires are damaged. Make sure they are all hooked up correctly. Now, it is possible that you could have a bad camshaft sensor or crankshaft sensor. In some vehicles, the camshaft sensor is built into the distributor. You want to test each of these parts and make sure each one is getting power. If a part is not getting power, that may be the reason your vehicle is not starting. If you have a check engine light on, you need to get your computer scanned for error codes. More then likely, if your vehicle won't start, your check engine light is on. The light is on because your computer has detected a problem with the vehicle. You can buy a cheap code reader for around forty dollars from Autozone or Advanced. Just make sure you know all your codes for your vehicle. When you have it scanned, the computer may know the exact parts you need to change. Most of these parts listed run off your ECM. The ignition system is a very complex system. It is rarely, but they do go bad. If you believe that the computer is to blame, make sure you have it flashed before you put it in your vehicle. If you don't, it will not work. Finding your error codes is the best way to finding your solution. If not, you will have many things to check. Always make sure you run a test on a part before changing it. Make sure that part is getting power. If it is not, check the power source. I know this is a lot of information, but any of the parts listed can cause the vehicle to not start. If you have no access to a code reader, fuel pressure tester, or a code reader, you can still check a lot of things. It is just harder. Remember, always use the process of elimination. Determine if the part is working or not and move on to the next part. You will eventually find your problem. Lastly, electrical problems can cause the symptoms you are having. They are very hard to find. When trying to find an electrical problem, you need to make sure you know what to test for. Each wire has a purpose. One part of the engine can shut down another part. You need to know how many volts you are testing for on each wire. You can use a voltage meter to test for current. I hope this helps you and thank you for reading. Thanks for using FixYa and best of luck

OK i have a 1999 gmc Yukon i just changed the fuel pump spark plugs ing coil control module wires but she still wont crank she starts then shuts off whats wrong HEPL ME PLZ


I suppose that you mean it starts but doesn't continue to run. And if you try to start it right away it'll just crank. The fuel pump is on in crank but not in run ( maybe ). Find the fuel pump relay in the underhood fuse relay panel and use a test light to cheak the pins for power and ground. First with the test light hooked to a good ground, check to see if it works first ( touch the battery positive ) then touch all the pins of the relay ( removed ) One should be hot all the time ( if not the fuel pump fuse is blown) another should be hot with the key on. one of the others will be hot only in crank ( this is the fuel pump) The last other is ground with the engine running after started. The one thats hot in crank put power to it with a jumper wire and start the engine ( it'll run ) the fuel pump also gets turned on by the oil pressure switch and the fuel pump fuse is blown it'll also not run the engine. But it'll run right after it's cranked and quit

No electricity to the fuel pump ...if I remove the pump and hook it up to a 12v source it works fine...hook it back up to the two wires on the car..nada


Well all your problem should be is either the feed to the pump is not there OR the earth wire isent earthing SO get a test light put 1 end to any part of engine and the other to the pump feed wire if it lights up then you have feed so its the EARTH so fit a new earth wire from engine or body to pump and away you go,,,,,,But make sure that the petrol pipes on on the correct way

Fuel pump not getting power


First check the fuel pump relay the easiest fast way of doing it is turn your key forward and listen for a click. If you hear a click then you might have hooked something up wrong on the pump or the plug that plugs into the fuel pump on top of the tank is not seated all the way down.

(If you bought a rebuild kit and not the whole fuel pump assembly)

As for the fuel pump only two wires go to it a red one which is positive and a black one that is neg. And it's marked on the top of the pump.

89 thunderbird - 3.8 Car dies


i had this problem on my 88 t-bird 3.8L. not exactly sure of the cause but to remedy mine... it seems the computer was not telling the fuel pump that the car was running. so the fuel pump would quit pumping. run a wire from your battery to the positive line going to the fuel pump (temporary). if this solves the problem (and you don't mind solving it this way) make the wire run clean and hook it to a switch so you can turn it on when you wanna drive. this is not the way a dealership would fix it but its also not gonna cost you more than you probably have invested in your car. hope this helps
