Dodge Repair: 1996 dodge ram 3500 van: no start, dodge ram 3500, exhaust gas recirculation valve


Question
QUESTION: r&r transmission now engine cranks but won't start.

ANSWER: Hi Wayne,
Have you tried for fault codes using the ignition key:"on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the check engine light, which remais "on", to see it begin to flash, pause, flash, etc. Count the number of flashes before each pause, then repeat the process to be sure of an accurate set of flash counts. Tell me the counts in order of appearance.  We'll go from there.
Did a shop do the r & r so that they might take responsibity?
Please 'rate' my answer (see below).
Thanks,

QUESTION: Hi Roland  first no a shop did not do the work. a couple of shade tree. Now i did the key trick.it flashed 2 times pause 5 times pause.  thanks

ANSWER: Hi Wayne,
Did it also then do a couple of 5 flash sequences? The last two sets are supposed to be 5 and 5 for the number 55 which means "end of code readout" and corroborates that the readout was done successfully. So if the 2 and 5 were first, then those are the number 25 which point to a problem with the electrical circuit of the automatic idle control "motor" which is merely a rod with a tip that move and in so doing change the opening of the idle air side-passageway of the throttle body. You would want to verify that the electrical plug was reconnected for that aic motor if it was disconnected in the re-build.
Thanks, and you can give me another rating/nomination if you so choose.

QUESTION: hi roland    i checked the fault code again. your right the
goes 3 2 5 5. if you could let me know. you've been a great
help thanks again

Answer
Hi Wayne,
The 32 code is pointing at the exhaust gas recirculation valve not responding properly. If the stem of the valve were gummed up then it tends to not close all the way which it has to do when you are trying to start the engine as it makes the mixture too lean.
So find that valve in a small pipe that branches off one of the exhaust manifold (if you have 2) and then look for the valve stem located between the round vacuum-actuated top and the body of the valve in the pipe (it may hidden by a flange that connects those two parts). Spray some WD-40 on the stem where it enters the valve body, then notice there is a slot in the stem into which the tip of a screwdriver will fit and you can then move the stem back and forth to free up the 'action'. An internal spring-action should move the valve stem to a dead stop in the closed position if you have it loosened up.
