If you ran the truck very low or out of fuel this code will be set and MIL Lamp will illuminate, otherwise if everything is ok and truck runs fine it may be a sensor fault.

Got a 2000 chevy truck with a 5.7 motor it is running extremely rich and has a mis and showing a code of 1345


take to autoparts store, have them pull trouble code, have you replaced the OXYGEN sensor ? do it ! whens the last time you replaced both the AIR & FUEL filters ? do it ! find out code, its probably a sensor ! oxygen, like I mentioned . the MAP sensor could also be fauty . anything to do with air & fuel delivery !!! VACUUM lines, check them all, replace as necessary, TIGHTEN the mounting bolts to THROTTLEBODY, maybe the gasket is leaking ! put fuel injector cleaner in tank, next fill up . when you replaced distributor, did you replace the spark plugs & plug wires ? very important !!! EGRvalve, this valve gets clogged up severely choking the engine on these trucks !! pull it off, take a look, clean it or replace it ! when you set timing, did you follow the manual, some require you bypass the EST system, by unplugging its connection . (electronic spark timing). usually located @ firewall, under relay cover. replace the knock sensor ! todays fuel is BAD for your truck, you may think you have a miss, when you inturn have a "spark knock" , replace knock sensor @ engine block ! I think we covered it, balls in your court, hope I help you , its never just one thing, truck needs a maintenance day !!!!!!!!!

How do i reset po148


Are you asking how to fix the problem or just how to clear the code?

To Fix:

P0148 is a 'Fuel Delivery Error' - generaly means you are not getting enough fuel flow/pressure to the rails. This can be caused by the fuel pump, fuel filter, or fuel pressure regulator. You need to determine the faulty component by testing with a fuel pressure gauge and replace as necessary.

To Reset:

This generally requires a scan tool. Most shops will reset your codes for little/no cost. Some parts stores also have readers capable of resetting codes.

Hope this was helpful. If you have any other questions feel free to ask.

2003 ford f350 with the V10 gas engine Engine died while going down the highway and now won't start (engine doesn't turn over). When the ignition is turned to "on" we don't here the fuel pump priming...


ummm that could very well be the fuel pump... you want to check the fuel pump fuse and also the solenoid thay do go out but most likely the fuel pump has gone out one way to check and see if its the fuel problem is to spray some carb cleaner in the air in take and try to start if it dos and dies that means your not getting fuel delivery also test your pump delivery pressure....the fuel pump is located in side the fuel tank...
