    the van is a 1994 dodge ram van B2500 with the 3.9L v-6 by the way. i pulled codes 12, 45, and 51 from the ecm.

  • petewagenaar Jan 03, 2009

    dry gas and a full tank did nothing. as for the codes. disconnectted the batt for an hour, van started and ran fine for a bit but the problem came back within 3 drive cycles.

    that apparently is what the codes are that you are getting... disconnect the battery for about 15 minutes should reset it and clear at least the first code

    12


    Battery input to PCM disconnected during last 50 key starts.




    45


    Overdrive Solenoid open or shorted





    52


    Oxygen feedback system stuck at rich position.

    fuel or a plugged cat converter are what i'm leaning toward.... when you are driving at speed... highway or city how does the vehicle act... misfires or sluggishness ?

    does it backfire at all when you attempt to start it ?

You will find you have a code 12 again... you are in "limp home" mode.... you need to check either the overdrive solenoid or the o2 sensors

I have1990 Chevy Astro van,it starts just fine,when it warms up,driving it or sitting still in drive or reverse, it stalls,I start it back up,in park or neutral,it stays idiling.Idles cold,stalls warm


Check the ECM grounds, they are under the passenger side kick panel. When the engine goes to warm status, the Oxygen sensors come on, If there is no ground on the ECM then it starts pulling ground voltage across the sensors and that causes big issues.

I have a 98 isuzu rodeo and it wont stay running unless I keep my foot on the gas. The check engine light isnt on so I have no clue what to do, can anyone give me some suggestions please?


hot or cold engine,or both????????????????????
sure...
the ECU works OVERTIME; hard, to keep the engine running.
this is done by the action of the ISC valve.
so can you keep it running with a fast right foot??????????
a real mech needs to drive car.
does it have full power on hills?
is the tune up service done, the 60kmile repeats and needs to be done.
the ECU can not keep idle right on any engine that runs like crappppppp.

1: all fuses good.
2: engine never warms to normal 180F+ temp and hold???
3: not tuned up.
4: engine misfiring.
5: engine flooding.
6: engine starving for fuel.
7: OMG, the ISC wires fell off, (inspections do work on old cars)

there are simple tests. for each case.
one more #8. EFI system lost 12vdc power. stalls.
12.6vdc not running, 13.3v -15v running.

Astro van problem


If the engine RPM drops and does not recover, its usually a faulty idle air control valve. Can you keep your foot on the gas and keep it running when you come to a stop ? Is the check engine light on ?

1990 jeep wrangler runs rih won't stay running replaced map sensor and temp sensor


which engine,? the have up to 3 choices.
rih?
what are the full symptoms,
did you do the full listed 60k mile tune up on car?
sparkplugs,wire, cap rotor/filters? no engine runs right with bad spark
unless it's a diesel.
starts good
runs good or bad hot or cold engine
idle at 800 RPM hot?
stalls> when hot and cold engine
lost of power
bogging
misfire,
learchs>

only stalls , but runs perfect even up hills, at wide open throttle.
fresh gas, or 1 year old?fuel.
can your fast right foot , save the stall, and easily?

ok stalls 101.
1; lost 12vdc to EFI system.
2: lost engine compression.
3: lost spark.
4: lost fueling or floods
there is a simple test for each.
do you want more guesses, or how to do tests.
can do both, but my guessing fails 99 /100 times.

tune it up
do the right foot test. those are always first. on stalls.
always.

Car wont stay running unless foot is on the gas pedal


is the CEL check engine light out running? (it comes on stalled, and is normal that)
stalled. engine stall. no year, now that makes this 10x impossible
and even more impossible no engine stated, (displacement or VIN)
F22? 2.3. 2.7? 3.0L?
if in usa, (no loctation stated ) open hood, look up, see tag?
see vacuum EPA map, see engine type? bingo.

so I wall answer in the generic, (ALL CARS gasoline)
fails hot or cold engine, does hot engine reach 180F and hold?
wow, how low was the oil, off end of stick, none?
stalling is caused by over 50+ things. (we do tests to find it fast )
we use tools, do you have tools, or can buy them, or do you just want
endless guessing. here is the path.
#1 stall maker is a stuck open EGR main valve, ignored during the turn up, clean it. make sure it close
in the macro,
1: bad engine, the hot engine can lose compression and stall.
tool1 the $20buck compression guage.
2: bad spark, or timed wrong. gapped plugs wrong, wrong plugs used. bad wires sets, (old dizzy engines) bad COPS newer cars.
check for hot spark at all spark plugs, skip none.
3: bad fueling (too much or not enough
if engine runs perfect and only idle is too low 800 hot is normal
no DTC 300s misfires, then maybe the ISC is just dirty.
we clean the EGR and ISC every time.
if the EGR leaks, the fast right foot can save a stall but is hard.
if the ISC sticks closed, saving the stall is piece of cake, super easy
after all , you are adding the missing air.

does that help,. no, then take it top the man, the ASE man.
The Mechanic.with the ASE patch on his /her sleeve.
no year, ouch.
