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.
98 ram 150 cranks-no start replaced ecu repl crankshaft senor twice repl cam senor when the asd relay is in i get link error when i jumb it out i can get error codes from my ecu still no spark can hear fuel pump running all the time bu no fuel thru injector or cylinders is there an infiler on gas line and is the a fusible link on the ign
when the relay for the asd is installed i get link error on my scanner when i jumb it the computor lets me know error codes same with fuel pump when relay is in it runs all the time when the ign switch is turned on
dash board guage on a no start 98 ram 1500 5.9 no spark fuel pressure at rail replaced ground wire from alt bracket to batt still no start
Check fuel regulator pipe connector
Have a 1998 dodge 1500 that will not start. Engine turns over fine. None of the guages are working now. Warning lights do come on. Any suggestions
Change your computer. Thats exactly what happened to mine. Dodge has to program it.
Already replaced it. Still no change
Well I'm hearing that you don't have to have it programmed, that it should work. .
I've got the same problem with my 98 Ram 1500. No spark. Engine turns over fine. Gauges not working. Have replaced sensors in the recent past. The only thing I haven't changed is the computer. Thoughts?
I have a 98 5.2 dodge durango it turns over gets gas spark and good compression but won't start help please.
I have a 98 Durango 318 has spark and fuel still wont start i replaced coil and crank sensor checked asd and fuel pump relay come to find out i was not getting power to my asd jump it truck ran for about a minute then died now i have power at my fuel pump relay but no fuel pump help
98 dodge ram 1500 5.9 4x4. no spark no fuel pressure at rails. have changed plugs,wires,cap, rotor, pickup coil, ing coil, crankshaft sensor twice. Now the innova diag tester is saying asd relay circut, asd relay power, & still says the cranckshaft senser.. Yes it turns over but thats it. Any help???????
I have a 1998 dodge it will start and run,I can trun it off come back to start it agin it will not start. Sometimes it will or will not. It got spark gas , let it sit over night it starts.
Dogdog13. Ur fuel injectors r clogging. Use seafoam or a good injector cleaner.
chassis grounds. go through and clean up all your grounds. a good one to start with is behind the drivers side headlight where the cruise control module normally is. get a distributuion box (8 channel) clean your ground post(not battery tho u could clean it too) and put 4 new ground wires running to the dist. box. 1 to each channel. seperate all accessory grounds and clean them up. seperate them into 4 manageable bunches and put new eyes on. run a maximum 2-3 wires to an eye. each eye gets ran to a grounded channel on the dist box. then u need to ground the dist box. i used a ceiling fixture mounting plate and grounded that seperatly using the green ground terminal screw
not going to solve all your problems here but was on my mind. i havent regretted the brain fart that led me to do it yet except ive got the same prob with 98 ram fuel pump. fiddle around with what u got before u hand over to charity... lol. always something simple. but could be a MAP sensor too... idk
most them wires r copper and guess what? copper gets junky pretty quick
i have a 1997 dodge ram 1500 its getting s but wont start just keeps turning over then come out day later starts i replaced all sensors evtything still doing it driving me nutts after all the money i put in it HELP PLZ

I've got a 98 Dodge Ram 1500 V8 5.9. Was driving down the road and the truck died. Pulled over to restart and no luck. First thing I noticed was the fuel pump wasn't turning on. Replaced with a new one and still no power to it. Checked the fuses and relays. While trying to restart with new fuel pump I noticed the odometer was flashing. I was told maybe the ECM so I replaced it as well. No luck there. No codes before and none now. Will only crank.
i have a 98 ram no start replaced ecu a third time fuel pump runs all the time when key is turned on no codes after 4 years i am either donating or junk i getting another truck that runs most likely a Ford people have said look for a fusible link i can not find good luck to you guys with a no start ram i am fed up if you find a fusible link post it
Happened to my 98 318 yesterday while towing a boat uphill. All sensors, fuel pump, ign. wires, cap & rotor changed within 5K miles. NO CEL. Acting like out of fuel but tank full. Tweaked coil wire at coil. Started fine.. Put in Drive.. Stalled again within 10 seconds. This time removed and reseated coil wire at Coil and Distributor. Jiggled power wire to coil connection. Started fine and got home.. Ordered new coil. Will update...
never got my 98 ram running replaced all sensors fuel pump coil 3x still no spark or fuel the only thing fuel pump runs all the time i think there is a fuseible link which i can not find i tried for 4 years and i give up will be getting something else and junking ram
Even after replacing the coil, same thing happened to me yesterday. At least it starts if you wait 3-5 minutes after it stalls. I guess I was wrong about replacing ALL sensors.. looks like I missed one.. so I am going to try replacing the Crankshaft Position Sensor now.. it seems to match the symptoms.... randomly stalling and then restarting with a short rest... Will update again..
Replacing the Crankshaft Position Sensor resolved my issue.
On my 97 I had same issues. No fuel no spark. Replaced everything that could be related and still no luck. I ended up cutting the 8 volt supply for crank, cam and vehicle speed sensor at the pcm. Soon as I did everything worked like new.
i have the same problem what color is wire that you cut for the crank-cam and speed senor
