Need to listen for fuel pump humm for proper operation. Shoud humm for about 3 seconds with key turned in the on position. Humm will sound from gas tank where the pump is located. If it does not humm. possible Faulty Fuel pump relay or pump. It will need ferther diagnosis.

I have a 98 and we just had a cold snap where it was super cold and I didn't start it for about a week. I had just got a new battery because mine tested out bad. Everything was good but now it doesn't want to get fuel. Cleaned all battery and relay connections and it's turning over great and fires with starting fluid but won't start. Guy at Napa said the fuel pump on these are known to not work well in the cold and suggested to warm the tank. I'm parked outside and can't move it to get it inside somewhere. Anyone know of good solution to this fuel pump not working in cold temps issue?
It is possible that you have some water in your fuel. If so, it can freeze if the weather is cold enough and prevent fuel from getting to your engine. If you can somehow warm the car up a bit, you can put some methyl or even better isopropyl alcohol in the fuel and run it for a while. Note that if it IS ice, it will go away as soon as the weather warms up enough. But it is a good idea to run some methyl or isopropyl alcohol, even if you do get it started when the weather warms up, so it doesn't happen again. It is very unlikely to get water in your fuel at a gas station. It happens due to condensation in the gas tank if you don't fill it up every time you get gas. If you keep it fairly low all the time, it will take a lot of moisture from the air. The methyl or isopropyl alcohol will blend with the water and allow it to burn off.
Most important- tune-up! Make sure your plugs, distributor cap and rotor (if so equipped), air and fuel filter are OK and have been changed (at minimum) according to your owner's guide.
If your vehicle cranks over slow when cold-starting, consider a new battery. In cold weather, batteries lose efficiency, and older batteries lose more power than new ones.
Next... Gas - the fuel in cold weather states has a formula change in winter months to lower emissions- sometimes going to the next higher grade of fuel (example: from regular to mid-grade) helps.
If you have a garage, keeping the vehicle inside makes a huge difference with cold weather starting.
Keep your fuel tank full. Running the tank down and leaving it near empty most of the time allows condensation, which will result in getting water in your fuel, leading to hard starts and poor performance, and the increased risk of "rusting through" which will cause a leaky fuel tank.
There are many things that could be the cause. Start with the easy stuff first. Make sure you have plenty of gas in the tank, at least a quarter of a tank. if you are in a cold weather state (below 32F) add some dry gas to your tank, make sure it contains isopropyl. Change your fuel filter(s). Let's start with this and assume it is a fuel problem, or lack thereof. Reply back to this post and let me know.
Have you the vehicle tuned up lately? Bad spark plugs will cause hard starting in cold weather also, the fuel filter could be plugged or it may have moisture in it. I guess, I would have those items checked and also, have the fuel pressure checked, the pump may be getting weak.
If your diesel filter has a bleed valve on the bottom I would try to bleed the water out. Most companies call the fuel filter a water trap for good reason, It wouldn't hurt to just change the filter and add a fuel drying agent to get the water out of you system. If you have a lot of very cold weather where you live it is best to keep the fuel tank full to avoid condensation from building up inside the tank.
before you try to start her again in hot weather, open your fuel filler cap, listen for any pressure release, close the cap, and try to start, if this works,then its just heat expansion in the fuel tank, replace the filler cap if this is the case
Possible flooding, cold weather can freez open injectors causing them to leak into the cylinders. Press the gass pedal all the way to the floor and crank the engine for no more than 60 seconds. The cylinders will clear themselves allowing proper mix of air/fuel and should start easy. If that does not solve please specify if the engine is 1.8l or 2.8l.
I'd Start With Checking The Spark Plugs, This Can Be Done By Pulling Them Out And Setting Them To A Ground And Trying To Start it Result Should Be Spark Obviously. With The Cold Weather Involved Id Try Cleaning My Valves If You Wanna Go The Easy Way Buy A Can Of Fuel Additive Injector Cleaner And Run It through A Full Tank Of Gas.
