    Had a misfire in the 6 cylinder I tested the compression and found I had excess fuel spraying out when I released
    The pressure. I checked 2 other cylinders and didn't have the fuel spraying and had compression at 120

    What does P0420 mean? Check engine light has been on for about a 1 1\2 weeks, thought is was the gas cap,usually is.
    I had an oil change yesterday and an air filter change as well. My fuel is now depleting rapidly,what should I do first. By the way it has some other codes: 01 misfire,fuel,comp,catalyst, & evap 02 sensor, htr, & egr Don't want to get ripped off by dealer,what ...

      You should be using Google to look up your OBD Codes

      TYPE: OBD PO420

      You do not use a vehicle with a check light on

      Within 24 hours you check for codes
      then decide based on the codes if you should continue to use it

      All code related issues should be repaired within a week weather
      your using it or not

      You have cylinder misfires to correct first

      Could very well had them a long time & ruined
      the exhaust converter (PO420)

      Being ripped off is an act of Fraud (where one takes money & performs no work)
      That seldom ever happens

    I was driving my car at 79 mph and it just lost power. The radio and lights still work. clicks when you turn ignition.
    It just seems like the battery is dead. But we have tried boosting it off it just seems like it is not getting any power to it.

      When you come here please do some testing first

      Seems like doesn't tell us much

      Is the battery dead & in need of replacement? Have it tested

      If you try & boost or jump a dead battery it could explode
      You can not push Current thru a dead battery thus you got nothing-one possible problem

      Did you check for OBD Codes?

      Did it go into Failsafe of some type?

      2.4 is that a timing belt motor? Did it come off ?

    My truck started overheating at high speeds ..but would cool down at low speeds I noticed my radiator cap did not
    have the rubber on the bottom put new cap and it blew head gasket codes everything used blue devil fix head ..still using old cap b/c don't want to blow head again still overheating at high but not low speeds why did head blow from cap and how do I fix the overheat ...
    • Teddy B
      12/11/2014 Teddy B
      I guess your saying you believe you had a head gasket issue & never resolved it

      The worst possible thing you could have done was put Blue Devil in it

      You can not get that out-ever

      Now the radiator & the heater core & other items will be ruined & blocked up

      Do the required testing to confirm a heat gasket issue & replace them if necessary

      There is other work needed as well be we will go into that when the head gaskets
      go one & before you add coolant & start it

    What are the causes of no compression in one cylinder it had a spark plug burnt the end off
    code scanner says misfire in #4, #6, #8, compression in 4 (140#) #6 (160#) #8 (0) other cylinders checked are 160 +/-10
    • CVO

      A broken valve could be the problem of the # 8, squirt a teaspoon of oil to seal the rings and retest # 8.If the compression # 8 doesn't change, then check the valves.
      12/11/2014 Dale A. Byrd
      got it fixed
      had 1 burnt valve #8 exhaust 2 bent valves #8 & #4 intake

      is there popping out the exhaust or back through the t body if so then a valve sounds like the problem if not could have burned a hole through the piston also check to see if both valves are opening remove the valve cover and crank the engine watch the rockers they should move like all the others on that bank

    It wont start it will turn over theres no power getting to the pump
    i checked all the fuses and relays that i know about they are good and the fuel pump is good . i traced wires and as far as i can see there's no broken wires . any suggestions (no inertia switch appicable)

      1. The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, or if the turbo boost pressure reaches and exceeds the over boost cut-off point, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module. This causes the engine to shut down.

      The logic module monitors the relay driver. If it senses that the relay driver is not responding correctly it will trigger a code. If the logic module does not sense an absence of current when the circuit is open, or 12 volts DC when the circuit is closed, it knows that the circuit is open or shorted, and triggers code 42. In later models which used the SMEC or SBEC, the logic module monitors the output of the fuel pump relay output as well as the fuel injectors. If it does not see 12 volts DC when the relay is activated, it triggers code 42.

      Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start.

      “The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump.”

      For troubleshooting purposes only (don’t drive like this!), “you can try feeding power to the fuel pump directly. Connect 12V+ from the battery through a fused link to the positive terminal of the coil. That will back feed 12V to the fuel pump through the ASD circuit. If the pump runs [it should be easy to hear], the ASD relay is bad. If not, the fuel pump or its wiring is probably the problem.

      2. The powertrain control module controlled the fuel pump relay. Local auto parts stores might have the fixture to test the PCM or negotiate with the stores managers to obtain a PCM loaner for a test.

      Happy Holidays.

      We have to start over. Tell me how you know that there is no power going to the pump. I need details of where you checked and how. Remember this fact. When the key is turned to the "run" position (this is not the crank position) the fuel pump should run for two seconds and stop. You can check for this 12 volt signal in two places. Locate the fuel pump relay in the power distribution center under the hood. Remove the relay and look at the bottom of the relay. There are numbers stamped. At the pliug in socket - 30 should have 12 volts (use a 12 volt test light) at all times (even with the key off), 87 should have 12 volts with the key turned to run and in the crank position. 86 should be a ground every time the key is turned to the "run" position and this ground is responsible for turning the fuel pump relay field on which then lets 12 volts flow out of 87 (when the relay is plugged in its socket of course). A quick way to determine if you have no issue with the fuel pump or wiring is after confirming that pin 30 has 12 volts, simplay jump out socket pin 30 and 87 and that will bypass the fuel pump relay completely and the fuel pump should run continuous with it jumped and you should hear the pump running. After you confirm these steps I will continue. Its the only way I can help you, sorry if you already knoiw any or all of this but this is where I start.

      we did exactly that the truck will start every so often now but will not stay running . we ran a jumper wire from the fuel pump relay to the fuel pump power wire . i have had the fuel tank out of the truck to check the fuel pump i have it back in the truck it does not seem to be any fuel at the purge valve also

      Have you plugged in a code reader to see what fault codes are stored? This vehicle has an immobilizer built in so if something is wrong with the SKIM system (sentry key immobilizer) it will start and stall and will also set a fault code, usually code P0513. If you have another key try it. No mention in any of the posts here about reading codes, have to do that.

      i was able to put it on the computer i got two codes a P0463 Dodge - Fuel Level Sensor 1 Circuit High and a P0113 Dodge - Intake Air Temperature Sensor 1 Circuit High . i put fuel in the gas tank and the fuel light is still on and also the i checked the the iat sensor it seems to be fine

    My truck will not stay running / start
    there is no fuel at the purge valve the fuel pump works and it try's to start . the truck will fire every so often then quit right away the check engine light is on and the fuel gauge will not work either

      The check light is on--so what codes are in the systems?
      Have you googled your codes to see the possible issues
      with the codes
      The purge valve is for the evap system to remove fumes from the fuel tank
      Did you check fuel pressure at the motor
      Did you check for spark or listen for injector pulse

      By purge valve you mean fuel rail schrader valve (little tire valve)

      Then you have no fuel pressure or it won't hold pressure at the pump &
      only runs if you can ever get it started thus a failed pump module (maybe)

      Check the fuel system fuses (won't fix anything but have to know if they are good)
