1998 dodge ram wont start
We have replaced the fuel pump, camshaft sensor, crankshaft sensor, and
computer. We have checked all the relays and fuses they are all good. Any
help would be much appriciated.
air, fuel, spark, timing...cam timing...the fault lies with one of these~ you've got an air filter, you've got a new fuel pump (but do you have fuel pressure?) have you checked voltage at the coil? have you checked the ASD relay to make sure that it is enabled? have you looked at the timing marks?
More information is needed- you say it doesn't start- does the engine turn? Is it getting spark? Is it getting fuel?
Its cranking over but no start. Its not getting fuel or spark. We have checked the asd relay its working.
power to the coil...power to the fuel pump...check both~
We have power to both.
excellent, hate to suggest "starter spray---ether" but now that we have spark and fuel, should kick right over...do you hear fuel circulating through the fuel rail when you put the key to the 'on' position?
No that's the problem. We are getting power everywhere but still will not start. Fuel pump doesn't even kick on. We have even put two different diagnostic tools on it and is not pulling up any codes.
aha...the emergency fuel cutoff switch...have you tapped bumpers to snap it off?...there could be a reset button under the dash, near the fuel tank...kick panel...fords, and gm have them dodge has a "red button" somewhere...this one you need to press to enable the fuel pump if you can find it....if you know that the truck has been smacked in the front (maybe when it was towed?) disabling the high pressure source~....magic button...yes~(sounds grimms fairy tale, but most possibly)
okay here's the dope~ should be in the fuse box on the side of the dash on driver's side. If you can't find it just pull the fuse going to the fuel pump If your are looking for an inertia switch, it is not a Ford, there isn't one. ...that doesn't help, but what I've found on the subject~
We have pulled it. Still nothing.
"pulled it"? not quite sure what now...hopin' to get your fuel pump happy with 12 volts going to it~ The source for this power goes through the ignition switch, a fuse a relay before it gets to your fuel pump~...perhaps an emergency fuel cutoff, but you'd think they'd run that one through the Automatic Shut Down relay...wouldn't you?
if you've got power to the fuel pump...and it still ain't pumpin' would have to suggest that it is bad~ooooo sorry~
Ya we are thinking we are going to have to take it to dodge and let them figure it out.
well here are a few choices at any rate~
Thanks for all your help
what was causing the problem?
check your catalectic converter
About 2 years ago my 98 ram 5.9 died at idle in the dead of Minnesota winter and would not start up again. I replaced the can and crank sensors coil distributor and various other parts that I thought may might cause it. After all the headaches I pulled the valve cover on the right bank and low and behold I dropped the number 7 intake valve. Was able to put everything back together even after the valve hit the piston (piston still good) and never lost compression. This happened at about 165000 miles. To this day it still runs like a champ and has 202000. All dodges have that issue whether 318 or 360.
