1998 Doge Durango Won`t start?

Question

I am about to change the CTM because o fthe following. Auto started stalling,now it died and won`t start at all.Ihook up a scan tool but no communication error with CTM.I hear no noise from the fuel pump exceti when the black connector is disconnected from the CTM. No spark from coil. All crank,cam sensor have been changed.The thef light stays illuminated on the dash but it don`t blink.I am wondering if it`s the VTSS locking the CTM out. I did the spark test by applying power to the coil and it sparked.The auto crank but it won`t start. My last resort is the CTM about $300.00. How do I check to see if the CTM is defected if posible. Everthing elce work in the auto, light, door lock eaven the alarm go off when I set it and open the door. Also, the fuel guage don`t move when I turn the ignition on and the low fuel light comes on.

Answer 1

the ctm controls vtss functions. if it is not working and vtss is enabled it will not start. normally when a ctm goes bad none of the lights will work either. the only way to test it is to check all powers and grounds to it, test the pci bus wire at the ctm with it plugged in and unplugged to make sure it has communication. the ctm is in the left kick panel not the back of the cluster.

Answer 2

you need to also check the relay to the pump ,those will go bad and cause a no start situation,they also have pressure regulator that should read about 45 pounds of pressure when checked,id check those before i changed the ctm on it,usually when a ctm goes bad you wont have no lights working on it,so it might pay to check the pump and pressure before you go spend the money on the ctm,good luck with it.

Answer 3

Check the relay to the fuel pump, I had a similar problem and that solved it. You can also get a fuel pressure gauge and see if you actually have pressure, you can rent them for a couple bucks at the parts store. If it's multi port injected, you need at least 45psi or throttle body injected, you need about 15psi.

Answer 4

Get the instrument cluster checked. CTM is puggged onto the back of the cluster.

Answer 5

I think the first thing to do would be to check the FUSES,,,,, can you give more details does the engine try to start?

Answer 6

you can get a part at the salvage yard for a lot less
