Question about 1999 Dodge Ram
Do you have fuel pressure, lay down on your drivers side of the bed near your fuel fill and have somebody turn your key to the on position not turning over engine and listen for the fuel pump. Your should here it buzz. If no sound check the voltage going to pump. If no voltage could be fuel pump. You can also check your fuel pressure on the fuel rail.

SOURCE: Truck won't start replaced fuel
Is there check engine light coming on dash.Is the computer, re-programmed after you got it replaced.------
From where did you got main computer replaced.From local auto store or from dodge dealer.-------
Also get the crankshaft sensor.Is this sensor getting voltage.Is the fuel pump having power.Get it checked with meter.---------
Also how old is the car battery and starter.--------
Get the battery and starter voltage checked.
the starter checked.--------- To
test the starter try this procedure.
--------- Measure the voltage at the starter solenoid. Place the red probe on the positive battery terminal on the starter solenoid and place the negative probe on chassis ground. Have someone turn the key switch to "START" while you measure the voltage.The voltage should be approximately 12.6 volts. If the voltage is correct, there is a problem with the starter. Remove the negative battery post and check the connections on the starter.But if voltage is very low and less that 12 volts, this indicates its faulty solenoid.If you follow the wire from starter solenoid, it will reach the starter relay.That starter relay is a 12 volt part.If there is no voltage to starter or solenoid then its faulty starter relay.---------- Get this all possibilities checked and confirmed, this will point towards the faulty part causing the no start problem.--------- Thanks.Helpmech.

Try cleaning your throttle body. Over time on high mileage vehicles, the throttle body butterfly valve will gunk up with sludge, and dirt. This will prevent air from entering the intake manifold while the engine is idling, causing low idle/stalling. A can of throttle body/carb cleaner will do the job. First, remove the intake tube to get to the butterfly valve. Spray a small amount of throttle body cleaner directly into the intake, and wipe any excess fluid with a cloth. Also, inspect your air filter. I hope this helps

OBD II DTC P0113 - Intake Air Temperature Circuit High Input
This code means that the Powertrain Control Module (PCM) monitors the temperature of the air entering the engine. The PCM supplies a 5 volt reference voltage to the Intake Air Temperature (IAT) sensor. The IAT is a thermistor that varies resistance based on temperature. As the temperature increases, resistance decreases. Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.
There will likely be no symptoms other than illumination of the Malfunction Indicator Lamp (MIL - Check Engine Light / Service Engine Soon).
A code P0113 may mean that one or more of the following has happened:
Internally failed IAT sensor
Faulty connection at IAT sensor
Open in IAT ground circuit or signal circuit
Short to voltage in IAT signal circuit or reference circuit
IAT harness and/or wiring routed too close to high-voltage wiring (e.g. alternator, spark plug cables, etc.)
Faulty PCM (less likely but not impossible)
To solve it, first, if you have access to a scan tool, is there an IAT reading? If the IAT reading is logical then the problem is likely intermittent. If the reading is less than -30 degrees, unplug the connector. Install a jumper wire between the harness connector signal and ground circuits. The IAT temperature reading on the scan tool should be maxed out at the high end. For example it should be 280 degrees Farenheit or higher. If it is, the wiring is okay, and it may have been the connection. If it isn't install the jumper wire between the IAT signal circuit and the chassis ground.
If now the IAT reading on the scan tool is maxed out then check for an open in the IAT ground circuit. If you get no reading at all on the scan tool, it's likely that the sensor signal is open or the 5 volt reference is missing. Check using a DVOM (digital volt ohm meter) for a 5 volt reference. If it's there, then unplug the connector at the PCM and check for continuity on the IAT signal circuit between the PCM connector and the IAT connector.

The 'stalk' that controls all these functions is faulty. Your truck SHOULD still be under warranty...Take it in.
