The fuel pressure should be from 41-47 psi. I always suggest buying genuine Chevrolet fuel pumps. This and thermostats are about the only two things that I suggest buying from the dealer. The problem that you are having is the reason why. Aftermarket fuel pumps are very bad about only lasting a very short time. Another very important thing is getting the filter on the bottom of the fuel pump correct. If the filter lets even a very small grain of sand or anything off of the bottom of the tank in the pump. It will ruin it. 40 psi will make the vehicle run. But from that, I would believe that you are running an aftermarket pump. I would suggest replacing with a Genuine part.

    If the truck runs when gas is sprayed in the intake then I would say that it is the fuel pressure regulator. It is letting too much fuel go back to the fuel tank.

How do I replace the fuel filter on a Chrysler 1997 town and country 3.8 lxi


  • Relieve the fuel system pressure by removing the fuel pump relay from the power distribution center. Start the engine and allow it to run until it stalls. Try to start it again and let it run until it stalls. Repeat this procedure until it no longer will start. Turn the ignition off.
  • Disconnect the negative battery cable and raise the vehicle. Support the fuel tank with a transmission jack. Locate the fuel filter on the top of your Chrysler Town & Country fuel tank.
  • Remove the fuel line from the front of the tank and then the ground strap. Next, remove the inboard side of the fuel tank straps and front T-strap fastener. Lower the tank about 6 inches.
  • Detach the fuel lines from the fuel pump module and then remove the fuel filter. Put the new filter in its place. Tighten the fuel filter bolts to 40 inch pounds.
  • Reconnect the fuel lines to the fuel pump module and reposition the tank. Replace the front T strap fastener and tighten it to 250 inch pounds. Put the inboard fuel tank straps back and tighten them to 40 foot pounds.
  • Put on the ground strap and connect the fuel line in the front of the tank. Start the engine of your Town & Country and check for leaks.

    Hi!
    It seems your fuel pump fails at idle speed. I would first ensure that fuel pump is well fitted, no leaks, and good diaphragm condition.

    You don't give any info on vehicle, engine...etc, but I think your friend is right about the coil. You have to try and determine if it's fuel or spark. Could be your fuel filter....

    Do a flow test. Disconnect fuel line from filter to carb, point line at empty container and briefly run the engine. The pump should produce at least a cupful of fuel in a few seconds.

    Some possible solutions (from general experience (i'm 55 yrs old)): 1. Plugged up fuel filter; Replace it. Part costs less than $10.00.If the filter is just in front of the tank, it should take a screwdriver and 15 minutes or less to swap. 2. Water in the fuel tank; Add a bottle of "Heat" to the tank. Cost ~ $3.50 or less. This next may require some trouble shooting or head scratching first. DO #1 & #2 First. (Won't hurt & Doesn't cost much) 3a. Partly clogged fuel line. 3b. Cracked fuel line. (Sucks air into the fuel line) Depends where the fuel pump is.(Also look for fuel leaks, especially around hoses in the fuel line.) 3c. Clogged carb.Filter (if it exists). Verify fuel delivered to Carb by disconnect @ Carb. attach small hose to catch container then turn on (NOT Start) ignition.Should hav a steady flow of fuel for at least several seconds. If so, Replace carb. filter. 4. Weak/ failing fuel pump. Major pain but backyard mech can do it with helpmay take half a day.May need to have a few empty gas cans available to save the existing fuel.. Replacement In-Tank pump assembly should be less than $50.00.

    Cant get gas to injecters 2000 ford windstar it was 5 out last night and 25 out today weve been having problems getting it to start for the last 2 weeks


    Disconnect your supply lines to the cylinders. Try starting the car while someone watches the disconnected lines. If fuel pumps from the lines you need to have your injectors cleaned or replaced. More likely it is your fuel pump that has gone bad. If you dont see any fuel flowing from the disconnected fuel lines, try replacing your fuel pump and replace your fuel filter too just to be prevent pushing any dirt and sediment from a dirty filter into a new pump.

    2 solutions: first, ignition control module is getting hot and shutting car down. 2nd; you didn't mention your dash(service soon) lights were on.<p>
    You said the fuel filter was pretty clogged up. It's sounds like a bad case of EGS(ethanol gas syndrome). The ethanol;being a corn deritive;acts like corn liquor(which is what is is), and turns the fuel to goop, and adds large amounts of water through out all the systems.<p>
    It clogs up the fuel lines,the injectors, and ruins fuel pumps. It also puts heavy carbon on egr valves, int. and exh. valves, and can ruin oxy sensors, and catalytic converters.<p>
    Let's try the cheapest way first:Buy a can of SEAFOAM and Berkline 2+2 at your parts store. Take out the oxy sensor(s) and clean the ends using the 2+2 and re-install.
    Then change out the fuel filter again. Pour the SF into a tank of PREMIUM(only) gas. Change the pcv valve. Then start vehicle and let idle for 3-5 min(even if you have to rev it up to do it to get the SF flowing through the system), and then drive it 10 hard miles.<p>
    Replace that fuel filter, and then let it idle some more. Your car sounds like it is really messed up bad. Unless you take it to a garage that has a fuel system cleaner machine, this is the best way to do it.<p>
    After this, add SF every 3-5000 miles to your tank. It will prevent this from happening again. Also; to be on the safe side. Have a PSI check on your fuel pump. This goop could have burnt it up. I hope this helps.
