My 1993 dodge dakota cranks and runs smoothly to any destination, but if i cut off the engine,it will crank but will bot restart until the engine cools(about one hour) any ideas?
Have you run a fualt code test on the systems control mofule? You may have a defective crank sensor or cam sensor, the test will give a code.
For vehicles made after 1996, retrieving the codes of the check engine light in
your dash panel is simple. All you need to do is find your diagnostic connector
located under the dash by the driver side. You can then hook up a scanner and
the codes will be displayed for you. If you don't have any scanner like most
drivers, you can bring your vehicle to any local automotive store and they will
usually scan the codes FREE for you.
However, for vehicles made on or before 1995, there is only one
cheap way to get it: You do it yourself!
On board diagnostic (OBD) was designed on vehicles equipped
with electronic fuel injection so you can generally retrieve the codes yourself.
No need buying a scanner or
running to any parts stores to check the engine light. This system is called
obd1 and applies to most vehicles made before 1995 for domestics and 1993
on imports.
Dodge trucks have a
diagnostic trouble code retrieval method, Unlike Gm and Ford trucks the Dodge
line of trucks has no data port connector to gather codes from.
Instead Dodge has a ignition cycle
activation sequence that anyone can active by turning the ignition key on off in
rapid succession five times with the cycle ending in the "on" position.
Once this activation has started the check
engine light will start to flash. The first set of check engine light flashes
will be the first digit of the two number code. After the check engine light
pauses for a short time it will start to blink again starting the second digit
identification and completing the code's second number. If additional trouble
codes are stored in the computer the first digit will begin to flash, and then
the second digit. For example: the check engine light flashes four times, pauses
and then flashes three more times the code is 43.
The check engine light will flash one and then two meaning the
code gathering is over. The system will only flash 12 if there are no codes
stored in the computer's memory. To clear codes disconnect the negative battery
terminal for 30 seconds and reconnect.
Below are the OBD DTC's for 1995-previous model year
EFI-equipped Dodge vehicles.
