Re: 1999 galant doesn't get fuel
Fuel filter may be plugged. You need to confirm you have fuel pressure, unfortunately most people don't have a fuel pressure tester around the garage. Is it real cold where you are, if so, perhaps some gasline antifreeze may help.

A poor spray pattern in the injectors can cause starting issues. Have you tried a good (read not really cheap) fuel injector cleaner like Chevron Techron or Valvoline Synpower fuel system cleaner? A weak ignition system (worn spark plugs, leaking wires) can cause starting issues. You mentioned that it has a K&N filter on it. These filters use an oil in a cotton media to filter out dirt. Sometimes that oil can get out of the filter and contaminate the mass air-flow sensor. Follow the air tube after the filter box and you'll find a sensor in the tube with several wires running from it. It is made from aluminum and the wire housing is plastic. Remove it from the tube and clean it with a mass air-flow sensor cleaner. You HAVE to use a mass air-flow sensor cleaner specifically made for mass air sensors. Don't use anything else like carb, brake, or throttle body cleaner. Those cleaners will leave a residue on the sensor and just cause you more issues.
As for your fuel pressure, the system pressure with the key on, engine off is 60-66 psi. Do you really think you could visually tell the difference between 60 psi and 40 psi? I know I couldn't. You'll have to use a fuel pressure gauge to verify the pressure. For my money, I think your pressure is low. But, cleaning the MAF is much easier then putting a tester in, and it wouldn't hurt, so I would do that first.
change the filter first,, if that doesn't work, then spray some carb cleaner into the intake, ( or throttle body , and turn it over, if it runs as long as you spray ( don't use to much) then its probably going to be your fuel pump
but is the fuel pump working.if you remove the air snorkel and spray intake cleaner into the intake while someone tries to start the car and it starts then you have a fuel problem.either the pump,plugged fuel filter,fuel injectors not working,dirt in the fuel system.check the fuel pressure if it doesn`t start when spraying cleaner into the intake.
well first of all. check to see if fuel is reaching engine, the line may be frozen. if so, put dry gas in to displace moisture in fuel line. just make sure its getting fuel and spark. try this! spray some starting fluid in throttle body. and if car runs then quits then you have a fuel problem. im from n.y. state and it gets pretty cold here in winter. just remove air intake hose to throttle body to spray in it, the big hose from air cleaner. have a good day !!
1) Faulty connection to the Idle Air Control ((IAC) valve or the passage ways to and from the valve in the throttle body have become gummed up and need a clean. You need to remove all air cleaner pipe work. Spray IAC apertures with carb. cleaning spray and wipe with kitchen towel or cloth. The apertures are ports on the interior side walls of the throttle body immediately before and after the throttle flap assembly. The IAC can be unbolted and cleaned pretty easily.
2) Fuel pump fuse, faulty fuel pump relay, faulty pump or locked fuel filter- can do a collective check of all of these by simply disconnecting the fuel line and seeing the amount and pressure of fuel flow when ignition key in second position.
you may need to change the fuel pump,take a piece of wood and wrap the tank a few times,try it,if it runs for a while--its not fixed!!..then replace the pump because it could go all the way out at any time.
yes you should be able to hear the fuel pump run for about 5 seconds once the key is turned to the on pos. check to make sure you have spark. if you do try having someone spray air intake or carb cleaner into intake manifold while you crank. If the truck starts right up for a second (or stays running as you keep spraying) Id say you have a bad fuel pump and id change the sending unit also. (First check the fuel pump fuse and fuel pump relay) GMC and Chevy are nororiously known for having bad fuel pump/sending unit problems. I have prob changed over 60 myself.
Not sure about this as its got lots of electronic sensors and telling you it could be one or the other and they are not cheap,also its difficult to tell without being hands on so to speak.Basicly the fuel is pumped at pressure into the common rail which feed the injectors,pump is working when you crank engine so thats fine (pressure) now the ECU unit is controling it and when the fuel is injected ,but on older cars its spraying all the time.which i think your is.Now lift bonnet and on the end of the common rail is a round valve with a vacumn pipe on it,make sure this pipe is on and the ends not split and it has a vacumn in it when you crank the engine.Sorry dont do call outs outside alicante zone (spain) If pipes seem ok then its a garage job as it could be a manky wire inside a connection plug corroded .Best of british with it.
