[mattd424]

hey everyone i have a 94 ram 1500 with a 5.2 it sat for couple years fuel system was flushed and fuel pump replaced.my truck starts geat and idles but stalls sumtimes.i can drive it fine but it takes a really long time to get up to speed rpm not coming up i can litterally park on loose gravel and stomp it and itll just ease off and slowly build rpm it has a little white smoke while running and skips a little.ide really appreciate any advice

ok today i tested my coil with my fluke on ohm i get 1.7 ohm on plug in side and checking secondary from 1 plugin terminal and output post my meter doesnt register a thing.should my truck even run?

Sorry, the only trouble with ignition coils I can help with is if the engine won't start hot but starts fine cold.


After sitting a coupla years, it's likely the fuel injection is kinda gummed up.
I'd pour in a solvent cleaner like Gumout or Techron by whoever markets it now and just idle & drive the thing. Don't use the Lucas stuff....it has no solvents.

well over theese cpl days i drove a couple tanks with seafoam and yesterday took it to shop to have injectors cleaned.still no change bough new filter/regulator and installed it also

[Chris Stewart]

Was the fuel pressure ok?

Is there a possibility that the cat is plugged?

[mattd424]

yeah there prolly is a possibility its pluged fuel pres is 36 not sure what it suppose to be

[kevinb70]

supposed to be 45-55psi.

with the engine shut off 15-30 minutes do you still have pressure? (ie leakdown test)

exactly what injector service did you get? with it sitting 2 years i'd get the injectors rebuilt - check out Mr Injector on the web. If they serviced the injectors by just running cleaning fluid thru the fuel system then that's probably not going to cut it. Mr Injector will disassemble, clean, and rebuild the injector including replacing the internal filter inside each injector.

they charge $16 per injector. don't buy new unless they tell you one is bad. I'm about to do that myself with a car thats also been sitting 2 years

id address your fuel pressure problem first. might get adequate performance once thats fixed

All good info so far, but tap your cat converter with a rubber mallet or wood one. Listen for stuff bounching around.
Also pull your O2 sensor, see if that improves the drivability aspect.
