Question about 1999 Dodge Ram

Long cranking to start

Hi...im working on my dad's 98 24valve dodge 5.9 cummings...on cold start up or if its been sitting for a while, it cranks over alot longer than usual to start(usually hit the key and go..now it takes about 10-20 secs of cranking)...ive changed the electric lift pump...pressures were low 3-4lbs (should be 7-10lbs)....still the same problem...i tested the overflow valve on the injection pump and it seemed no good so changed it too, still same problem...ive looked for fuel leaks also since i found it was leaving small wet spots of fuel after sitting for a bit ...they were coming from the bottom of the bell housing ...i couldnt find any leaks at any of the lines or connections..so i put dye in the fuel and still cant tell were its coming from.......any help would be greatly appreciated....:)

    thank you for the reply ....

    as a footnote dodge 5.9 cummings dont have glow plugs...they have an
    intake grid heater......it appears to be a fuel problem...the fuel is
    bleeding back somehow...today i parked it on a slight grade with the
    rear end on the high side of the grade and after work it barked right
    up like normal....i think im going to have to take the lines off at the
    tank and put a bit of pressure to them and see if i can make them leak
    to see where the air is getting in

Good work!! Check the glow plugs for power & make sure you're getting fuel.

03 dodge ram 1500 crew cab 4.7l v8 starts fine when cold but won't start after it is warm


First i would check the crank sensor by looking for rpm's on the tachometer or scan tool if you see any rpm's then crank sensor is good.Then check for leaking injectors and if they are not leaking then you will need to check the ECM it may have failed.

Van runs good then stalls out. then hard to start. If i let it sit for 5 minutes it starts again no problem. Then stalls again shortly there after.


This sounds like a failing camshaft position sensor and weak crank shaft sensor .When crank shaft sensor gets weak it will stop functioning.When crank shaft sensor stops working then ECM will not control fuel system and the fuel will stop flowing. And this can cause the problem.When crank shaft sensor gets heated it will stop working, but when the car shuts off, the sensor gets cold and works for few minutes and sensor again gets hot and it stalls. ---------- Get the crank shaft sensor tested on your Chevrolet venture. ---------- There are many other possibilities for this stalling problem,but crank shaft problem is indicating in your case.

I have a 2002 chev silverado 2500HD duramax 4x4, The truck starts only when given a shot of quick start in the airbox. After it runs great you can shut it off then re start it fine. It will not start...


You need new glow plugs. Im guessing you live somewhere kind of cold maybe. It starts just fine after running because the motor is already warm. Quick start will work.....or at least it did for me until I used one mornig and went to crank and BOOM. It blew my air filter case to pieces and caught the filter on fire. Starting fluid is not meant for diesel motors. If you cant afford new glow plugs what worked for me is turn on the key all the way but dont crank wait 10 sec then repeat a few times and it should crank unless its really cold out or the plugs are really bad. Trust me thats what it is. I replaced mine and now It cranks right up even when its super cold.

Chevrolet Silverado 97 2500 Turck won't start


The GM's are notorious for losing fuel pressure,could be fuel pressure regulator,or a weak fuel pump....also check for rusted fuel lines that will lose pressure when sitting..both feed and return lines...

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.
