I just replaced the fuel pump a week ago it ran good for a couple of days but now it will turn over but wont start. Ive also been driving it without a filter for three days do you think that has anything to do with it?

Re: 1989 Jeep Wrangler Standard wont start
You have to check if this is fuel or spark related. You HAVE to put a
filter in the system or the fuel injectors will get clogged. Check for
spark first. If you have a good spark at the plugs, then your problem
may be fuel related. If uou don't have any spark, then the problem
could be a bad crank sensor.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Whats a nutter bypass? these are none for a few things that cause a no start, the first is a fuelpump, try having someone crank the engine and at the same time beat on the bottom of the gas tank with a rubber hammer and see if it starts, if it does then pump is bad. the next thing to check is check and see if it has spark, if it does then it a fuel problem if it doesnt then i would check the coil and the pick inside distributor. start with these things first. good day.
The starter is most likely the problem,tap on the starter lightly with a hammer while trying to start the engine,dont get run over doing this it will take two people,if the engine starts,the starter needs replacing.
Hi Dava224 i had the same problem with my 1989 CJ. when it was cold out i would pump the gas pedal 3-4 times before turning the ignition. it puts a small amount of fuel in the motor without stalling it out. it wont start as hard. another good idea is to keep some fuel stabalizer in the tank everytime you fill up. hope this helps
if you have an electric fuel pump that would explain the hum. unhook your incoming fuel line and blow the line clear, sounds like you've got some junk in your tank.it'll build up on the screen in the tank then fall off (at least partially) when your making turns or hitting bumps or holes. next time it's only got a gallon or so of fuel i'd drop the tank and check the pickup tube inside. sux but that's the only way to get to it. while you've got the tank off and out from under the jeep, might as well clean it out real good and replace anything inside (usually the screen) that doesn't look right, dirty etc. wouldn't hurt to run a bottle of fuel system cleaner in the next full tank of fuel either. preferably as soon as you put your tank back. good luck
I'm sorry, but I'm a bit confused regarding your statement where you said, "I drove it without a air filter for 4 days the put in a new one but it still wont start." Please clarify. Thank you, jetski224
This seems like a fuel pump or fuel filter prob. The pump more likely. Will it fire up with gas poured into the carb? If so the pump. If not, we will need to look for another prob. Don't buy parts you don't need! Frankster016
