Chuggin and draggin down bad

Do you have any check engine lights on? Most diesels have a safety feature that shuts down the engine and puts it in "limp mode" when there is a problem somewhere . It will stay in limp mode till repaired and the code cleared. You should get a code with a diagnostic.

I just got my g5.... and it was doing the same thing. But when it did it, the traction light always came on. So when i took it back they serviced the traction and cleaned some kind of Ir intake valve on the car. But it continue chuggin. but look.... when i needed my air for a hot day... it started to over heat. My dad replaced my fan fuse... it stopped... now when my fan comes on it lurches forward and sometime chugges... replaced the fan... it chugges no more..... your fans is workin on its last leg. Go to andys.com and buy u a 30 dollar fan.... itll help. Its been about four months and no chuggin...whoo whoo tell me how it goes

Your code, assuming it was evap related, also means other issues aside from a loose gas cap. Your fuel system "closes" down to purge unburned fuel back through the engine. A loose gas cap will stop this process, as in why the check engine light will go on. Also, there is a vent solenoid, purge solenoid, fuel tank pressure sensor, and a charcoal canister that are involved. My guess, but if you have a bad vent solenoid, you may have symptoms like yours. Any "good" technician can test this for you.

start by ck fuses and then relays.if all good chk safety sw.it should be behind the passenger or driver side kick panel

yep a bad relay will cause fuel pump problems.

Run into autozone or Pep Boys for free trouble code scan, then write it down and get back to us, or if obvious what problem is diagnosed, replace the part.

fuel filter is down between battery and motor . check coil packs

Under the hood on the passenger side is a fuse panel that has 2 solenoids that push in. One is the gas solenoid that sends current to the fuel pump to start car. If this is bad your car will not start. Know this from experience because after a mechanic put in a $500 fuel pump and the car did the same thing 2 days later I purchased the new relay for $11. Runs fine!

I think your problem might be your fuel relay which is situated next to the fuse box in the engine compartment.

sound like maybe a temp sensor malfunction, it is telling the computer it is warmer than it really is so it is not adding enough fuel , have the sensor tested
