ok i have a 2001 300m with 85k miles on it. on my way home the other day it just kinda died on me like it ran out of gas. i hadit towed home. checked it all over. sprayed some starting fluid in the intake and it fired up and stalled when the fluid was all gone. so i figured it was the pump. so i dropped the tank pulled the pump bought a brand new one. put it in . car started up ran for bout 15 minuites. backed out the drive way drove up the street and the car died just like the first time. i checked the scraider valve and it had very little to no fuel in it. so i figured new pump was junk. took it back and they exchanged it for another one. put this one in car started up backed out the drive for a second time. put it in drive hit the gas it bogged and died. and now it wont start again. im lost on what to look for. please help

 

Maybe you got a bad load of fuel that is plugging the filter.

 

there is no filter on the 300m or concord all you can change is the sock on the bottom of the pump. and even the 2nd one i pulled out was clean.

 

you need to look for whats causing the fuel pressure problems. did you verify that all the electrical is in proper working condition?

 

Might want to look for a kinked line between the tank and the engine.

 

well i figured it out! wasnt getting fuel up the line to the rail. i took the line off . inside the quick connect at the rail inside is a small ball with a tab on it. the fuel rail is to push down on the tab and allow fuel through. well it seized up and was stuck shut. i took the line up to advanced auto. we replaced the quick connect fitting with their fuel line repair kit . put it back on and the car runs GREAT!!!. come to find out that ball is a safety feature if for some reason the fuel line comes off the rail it stopps flow of fuel. honestly cant remember the last time ive ever seen or heard of that happening lol. but oh well 400 dollars toward fixing it and it was a damn $4.50 fitting
