| I have had this problem going with my truck for a while now. At first i thought it was the batteries cause they were gettin drained but the starter ended up bein bad by pullin almost 200 amps. So i replaced that and for the first 2 weeks or so its been fine and now its starting to start hard again or it just cranks and somtimes i get a sound like the starter isnt engaging but then after that it wont crank over at all. Then if i do get it started for the first 30 min or so the volts keep droping for a second then they come back up. I cant find out the problem and was wondering if anyone knows anthing of the problem | |

Replying to: mikeyd123 (Feb 13, 2008 7:58 am) and i have the same problem, will start at first then stall out, wont start agan till next day and when it does start that one time a day, it bogs a couple times like it wants to die. it runs for about minute or 2 before it dies. replaced coil, cap, rotor, wires, plugs , camshaft sensor. turn key can here fuel pump going everytime, good fuel pressure. when it does die out, check coil , no power. i dont get it when it will start at least once a day everytime i come home from work it will start up runs for a minute then dies. swap ASD relay around with other ones like it still no start. no check enigine light. hooked up scanner , no code. when it dies , no spark at plugs, engine cranks but doesnt fire up. next on the list is crankshaft sensor and then computer, am i on the right track anyone or am i missing something? |

My dodge will start when I leave the house. Runs good but when I turn it off sometimes it won't start. After it sets for an hour or two it starts. Have replaced the fuel pump and the fuel relay. Any suggestions what would be causing this?

| I am having an issue with my truck cutting out at high RPMs. I have a 5 speed standard trans and when I hit about 2200-2500 RPMs, it acts like it is not getting enought air or fuel. It blows white smoke at times. Any thoughts? | |

Power to the coil but no spark? Swapped crank sensor no spark? Any Ideas? Gonna Check ASD today... Be back to report later! |

Well Rechecked Fuel Pressure (Its ok 44psi), then rechecked ASD relay (switching it) then rechecked the Crankshaft and Camshaft sensors while hand cranking the motor super super slow (making sure to have the coil wire unplugged from the cap) while the key is in the run position. Both checked ok. Went back to the coil plug and checked for constant 12v and then checked other wire for a signal while cranking motor that seemed fine. I was so certain to find something... I traced wires from the coil to the PCM and checked for continuity both fine. (GRN/ORG wire left harness plug on PCM & GRY/WHT wire far right harness plug on PCM.) While doing so I then noticed the PCM Computer ECU whatever... was a junkyard replacement! (Yellow paint marker numbers and a big lakeview junkyard sticker with a check mark on it lol Also pry marks all around it from someone opening it it seems lol).. I was shocked lol ..I never would have thought this was already changed lol.. Im NOW thinking the PCM is just bad. Any thoughts out there....

Found out today from the customer when telling him the PCM might be bad I told him "its the computer above the enging under the hood missing the cover" he then told me the van over heated and blew out the radiator hose near the thermostat lol... He said he cut the hose down and changed thermostat and he might have the PCM cover lol... Hmmm Ok soooo the junkyard computer along with not being factory sealed was drenched in hot radiator fluid then drivin the very same day and for 2 weeks more before this (dead at a stop light without warning).... Hmmmm I bet the junkard PCM was fine without the cover lol until the hose bursted and blasted the PCM witch is right above the hose lol THANKS DUMB DODGE FOR PUTING A COMPUTER THERE! I GUESS BEHIND THE DASH or NEAR THE DRIVER FLOOR IS TO MUCH TO ASK! I will get another PCM I guess unless someone has a idea for me to try I love experimenting! |
