Won't start. Help

I left my 93 grand cherokee with my brother(we live in Alaska) for 2 weeks. He used it for a day and left the gastank on E. The car sat for a week unstarted while the temperature dropped below 15 befor I got back. I've been back for 2 weeks the temperature has been around 20-25 degrees for the past few days. Replaced battery after getting tested still won't start. It'll try to turnover but won't catch and start. Battery meter reads 11v. I put a bottle of HEET and 7gal of gas in the tank (20gal tank) a few days ago. Could the gas line have froze? Alternator gone out and made battery die? Please help.

A fully charged battery should read around 12.5 volts. Make sure the battery is charged and turn the key on- not start you should be able to hear the fuel pump run. Turn key off wait about 15 seconds and turn key on should be able to hear the fuel pump run. Try to start by spraying starting fluid in the throttle body and see if it takes off. If your fuel lines are froze the only safe way to defrost it is to move the vechile to a warm garage. The only other way I know is to get some heat tape the ones to keep water lines from freezing and wrap it arount the fuel line or try using a good hair blower. If your Alternator is bad it still should start just wouldnt stay running. One other thing running the gas tank below 1/4 tank is not good. Fuel pump needs fuel to cool itself.

hold the throttle open while cranking, see if it starts.

There is a silver rail in the engine compartment, with a small schrader valve right above the intake manifold. While someone is cranking, press the valve in on the schrader valve. Fuel should squirt out in a hurry. If it doesn't, buy an analog pressure gauge, hook it up to the valve and get a reading while cranking. This will tell you if you have fuel pump/clog problems, however I doubt that is the case considering fuels freezing point is well below 15*.

You can invest in a block heater if a heated garage isn't available, it's the next best thing.

I'm confused by your description. Does the engine actually crank? If it does not your problem is electrical, maybe a seized starter/bendix gear. Let us know, as there are thousands of ways to get the thing started.

The engine does crank. I'm going to look for the valve in the morning on sunday.

try holding your foot on the gas pedal while you try to start the jeep see if it starts!

If it does start then you either have a Air problem (not getting any air into the intake, check the Idle Air Control Valve) or Fuel Check throttle Position Sensor.

If it does not start, then it could be fuel or Spark, check for Spark at the plugs pull one of the plug wires off of the plug and use an old plug or take the plug out and place it into the spark plug wire boot and hold close to something metal (bolt) and try to start the jeep, if there is no spark then check for spark at the distributor cap, if there is spark at the distributor but none at the plugs, then replace Cap and Rotor. If there is no spark at the distributor, test the ignition coil.

Also, check for codes and let us know. Of course 55 means end of them.

Ok car starts. Started snowing meaning the temperature went up. Turned the key with foot on the gas like I've been doing and it started then cut off. Then it started and cut off again. Did that for about 8 minutes. Hooked the car battery to another. Let it sit for about 10 minutes then tried to start again. This time the engine would run for a lil bit while my foot was on the gas only. Engine still made noises like it wasn't getting gas and finally it made a sound(like pressure was trying to get threw). I heard a loud bang and the car started while foot was on gas and turning key. Now it runs. Thanks for your help guys.
