93 chrysler t&c awd changed fuel pump and filter, van ran fine again for about 2 months now won't start and don't hear the fuel pump. changed the oil pressure sending unit and still won

And you know the fuel filter is good? Could be injector problem: just as a check, spray some starting fluid into the intake and see if engine runs a few seconds. If it does, it is a fuel problem. Check injector fuse, as a start. Check fuel pressure. Check injector circuit. If engine won't start with starting fluid, check if you are getting spark. Problem may be in the ignition system.

Check spark plugs, leads, distributor cap & rotor arm, fuel pump, fuel filter, coil pack(s), relays, replace any items that are suspect IE Fuel filter which has probably not been changed since new even though they should be changed on all vehicles every 18 months, all of this can be done at home & will save you a lot of bucks in mechanic/garage fees,

there is a fuse in the dash fuse box for ignition i believe it is a 10 amp (red) it may be the culprit, i had a 95 with a 3.3 and the fuse would blow once in a while.

If it is a 3.8 engine change the crank sensor,they go bad on the 3.8 engines.

maybe you can reed this:
Get in the van and roll all the windows, turn off radio and a/c and kids. Basically you want to create a quiet environment just for a second or two. Now engage the key as if to start the motor but don't turn the key all the way to start the motor, just before this point. You should now hear a "buzz" or "wind" behind you towards the back of the van, just for a few seconds. This is the fuel pump engaging and pumping fuel. If you don't hear this wind then try it again. It has nothing to do with pumping the gas pedal. It is an automatic item that turns on then off quickly because it thinks it has shot enough fuel from the tank all the way to the motor to start up. If no wind then I'd check and even replace the fuel pump relay which is right above the battery towards the back of it. Actually you will see 2 relays there and they are identical. You could always just switch them to see if the relay was bad. The other relay does something obvious on the van that I forgot but it will be apparent once you disconnect both as to what the other controls. If the fuel pump relay now works in the other slot then the relay is good BUT your fuel pump is most likely bad. This stinks because now you have to lower your gas tank to replace the pump which costs $150 or so. It is easy to do but takes a good 3-4 hours and an almost empty fuel tank is preferred before you begin because the tank is already heavy enough empty. The only special tool needed is a fuel line disconnect tool which is a $6 tool at any auto store. If you hear the sound then the relay is fine. You might want to check to see if your fuel filter is clogged. Again easy to do but messy. Use that same fuel line tool and wiggle it between the end of the fuel filter (right under the van driver's side) and the line. It won't fit that well but just keep wiggling. Now press the line towards the tool and pull line back and it should pop off. Have a rag handy because fuel will drain from the loose end of the hose that goes to the motor. Now get in the van and quickly engage the key again. You should have shot a few ounces of gas onto the ground (I say ground because you should do this outside in a well ventilated area and NOT in your garage). This means your filter is fine. Next I'd check your spark.

First try and change the fuel filter. this also happened on a van i worked on. I cahnged the filter and it runs fine now.

Was the fuel filter replaced when the fuel pump was installed? A clogged fuel filter may have been what took out pump#1, and it can quickly send pump #2 to the happy hunting ground also.

put a funnel in the gas nozzle have someone turn ignition on to almost start, but don't. You should hear pump running before you start your van if you don't hear the pump you know you have a defective pump if you hear the pump purchase a fuel filter try that if not possibly could the relay not sure where its at but could finds out for you.good luck

I suggest to check fuel pump pressure,also can you hear the fuel pump with the key in on positionyou should be able to hear fuel pump prime the line

the owner probably rerouted the fuel line because like my 92 chrysler lebaron v6 3.0 the fuel lines keep seeming to come off and the clamps always break. I have replaced the clamps 5 times in a month and replaced filters 2 times in 2 months. The only thing i could think of is that your fuel is being cut off possibly because there is no filter to clean all the junk out. Try putting a fuel filter on and see if that will work
