2000 dodge 1500 van 318 motor cranks on third try every time then idles high wile running it idles at 35 to 40 mph with foot off the gas does anyone know the problem?

Dodge RAM 2001 1500, pickup not the 1500 van. 5.2L (gas)
GAS NOT 5.9 DIESEL SURE
cranks fast
but will not start or does for 1 to 10 sec and stalls.
there are 50 causes, and 1 to 20 test using lots of tools to find it.
is this you asking for how to guess it or how test and find the cause.?
ok that gas pedal trick keeps it going, a A#1 top clue here.

I guess you have no scan tool to fix cars/ diagnose it?
working BLIND on any modern car lacking scan too will be costly guessing 50 times. for sure. scan it. first. after all fuse checked for GOOD.

the IAC on this car is a motor controlled air air valve for idle speeds
hot or cold engine both and 100% PCM controlled,
IAC is what controls idle

ASD (side show of vast)
there is also ASD if the PCM sees errors (overoload) OUT OF ASD RELAY OUTPUT PIN IT DROPS THE ASD DEAD, AND ENGINE IS STALLED ON PURPOSE, JUST LIKE ALL JEEPS DO. AND DODGE.
CLASSIC CAUSES THERE, ARE SHORTED INJECTORS OR SHORTED O2 SENSORS. DEAD SHORTS.
BUT I BET NOT ASD DROP OUT FAILS.

The IAC motor is located on the back of the throttle body.
below is the IAC motor schematic.
i owned 3 jeeps that had this, before throttle by wire.
all 3 the IAC gunked up, every 50km miles.(egr/pcv caused)

the ECT SENSOR sets cold start RPM, more air and way less air hot.
the motor simply jams with gun and needs top be cleaned (oldest story on IAC on earth)<<, common as nails .
I am having trouble on line de-mixing schematics gas;'diesel)!
so let me look at it all. now.
Gas has MAP: sensor
THE MAP INPUT PORT IS VACUUM AND MUST NEVER BE GUNKED UP AND BLOCKED, OR INJECTIONS WILL BE CRAZY WRONG
IT IS THE KEYSTONE SENSOR ! COMPUTES INJECTION RATES
BASED ON VACUUM.(PCM COMPUTES)


32 pages on PCM alone.
this 5.2 lists the IAC motor. as GAS.
the IAC is what I call a nose cone IAC motor ,
THIS IS MY BEST GUESS AS TO WHAT FAILS


FOR SURE RIGHT FOOT CAN KEEP ENGINE RUNNING GOOD
AND OF KEYED STARTS ARE HARD. ADDING 5% THROTTLE
MAKE ENGINE START FAST.

2 SCREWS IT OUT, CLEANED AND PUT BACK IN.
WELL I CLEAN THE INTERNAL SEAT TOO. ONCE OUT.

Have somebody stand in front of van with the hood open and watch the motor while you start the van.Put the emergency brake on and your foot on the brake,shift into D keeping your foot on the brake with your other foot give the engine a little gas and watch the motor.If a motor mount is broke the motor will lift up a little on the broken side.Be careful!

you may need to clean the throltte body, and then start the engine and hold the rpms high for a minute, then slowly reduce the gas pedal to idle, you blanked out the memory, now it needs to learn the idle speed again.

idle air controll motor is bad

I had a similiar problem on my 1999 Dodge Ram 1500 Conversion Van. It ended up being a partial collapse of the catalytic converter which didn't allow adequate exhaust. The problem only showed itself because I could not get over 55 mph going up a small hill.

replace fan speed reostat,generally high spd. does not go thru the reostat-full 12v service..kev-mn.

Have him remove & clean th IAC/AIS motor on the throttle body, and the port it came out of , as well as clean inside of throttle body if he hasn't done so already. Check and clean connections before re-assembling. Shouldn't take any longer than 1/2 hr or so.
