So i have been having trouble firing my car up lately. I JUST got the fuel pumped changed out (last week, $450 down the drain!!), thinking that was the problem........NOPE!!! It would usually turn over after 2 or 3 turns, but I tried it this morning and now it will not turn. I checked the fuse and its fine, I have no idea how to check the FPR. What ideas do you guys have? Thanks to all that help!

ever have the fuel filter replaced? These things will get pluged up and not allow nuch if any fuel go by.

Spark Plugs...

Fuel filter was changed about 3K miles ago and the spark plugs have about 12K miles on them. i thought about changin the spark plugs cause that would be the least cost, so i might do that today. But the fuel filter is brand spankin new.

So i just checked my fuel lines to see if any fuel squirted out as i turn the key so the fuel pump would turn on and there was no fuel. so now my new fuel pump is not working. its either broken or its not getting power somehow. any ideas?

bump- Does anyone know the voltage to the fuel pump connector? I am going to check it today.

So today i checked the voltage, (which was fine) and checked the fuel pump by disconnecting the output line and connecting a seperate clear hose to be able to see the fuel actually pump or not. Well i turn the key and the fuel started pumping, so now its definitely not the pump. I also unhooked the fuel line to the engine to see if the engine was getting fuel, but it never did. So this leads me to believe that the fuel filter is clogged. I know a couple of you suggested that, but now i was wondering if anyone had this happen after only a couple thousand miles? I should be getting a new filter put on tomorrow, so i will let you guys know what happens.

Did you install the filter? Did you or whoever installed the filter install it upside-down?

well someone else installed it, and would it run if the filter was installed backwards? its been on there for months like that. and to my knowledge it was installed correctly, but its possible.

i can almost guarantee it is engine coolant temp sensor try that next before you spend any more big bucks its an easy ten dollar fix. those sensors make are cars do crazy things.i had the same problem with mine.be sure to let us know if that worked or if you tryed
