Since it has been getting colder here in Colorado it has been getting harder to start. Now, not at all, engine is plugged in at night, and feeling the block, it is warm. HPOP builds pressure to psi in under 2 seconds, it's not making oil, fuel rail pressure comes up to psi in same time frame. Fuel pump pressure will drop off to 40 psi after 30 seconds of starter disengagement, then over the next hour will creep back up to 60 psi?

I put in a new cam sensor with no positive results. Any suggestion on what I should try? We are a small district with only 20 vehicles total and they don't have any electronic diagnosis equipment, Thanks for your time and any help you might have. Then post back your findings. Of course, this could be for a variety of reasons. Doesn't this engine also have a crankshaft sensor or am I wrong about this? I know the 's only had a cam sensor, but I think this engine might have both.

Can somebody answer that? Would this model have a separate injector drive module? I don't know as much about the models. It would probably be a good idea to check for codes using the above method. If there are any, they might help point to the specific problem. Cleared inactive codes after writing them down.

Am left with one code It basically says ecm asked idm for information, and did not receive any. Now I am in search of idm relay, or power source, and or idm to check for wiring problem. I will keep you posted on what I find. I did find that from - this engine did use one though. Thanks again A DTE, right? Those are cam sensors only. It's on the front cover, towards the right side, outboard of the fan hub, above the water pump.

Held in by one bolt which holds a retaining clip. I have been checking the IDM relay and wires. After I finished checking them I cleared the codes and rechecked the system for active codes, they are gone engine started right up. I will let it set tonight and see what happens.

Will uptake tomorrow, Thanks for your help and advice. That taught me something new!

At least I was not totally wrong I wonder why the s always had trouble with that sensor, but the DTs didn't seem to have that same issue? The original one lasted about ten years, since then, the replacements haven't held up near as good. I think I was lucky with the first one. If the 's had more trouble, my guess it would have been a spacing issue, or excessive heat issue.Welcome to world's most trustworthy automotive forum. Thread Rating: 35 Vote s - 3.

Reputation: I've got a 06 IH with a DT that won;t start. Replaced the IDM fuse is good now. When hooked up to servicemax it has a code. Servicemax shows no voltage on any of the sensors just dotted lines. I can read all the vehical info. Any help on what to look at next would be great. It can be caused when voltage is low to the IDM. Reputation: 3. I had this problem once and one of the relays was burnt out. I found the problem to be a wire rubbing on a bracket.

Check the wiring loom to see if it's not rubbing somewhere. I had on just recently that had a loose lock on the ecm causing the voltage to be low causing it to not communicate. Found it checking for voltage drops. Cleaned the pins tightened it up and ran fine. Also had a with and injector harness rub through on the power side blew the fuse when it hit a bump. On another the idm relay pins were burnt and were causing a high draw the fuse looked melted more than blown from the high draw.

I hope some of this helps good luck. Well I have got nowhere on this no-start. After replacing the IDM I checked all power and grounds, I even put a 12 volt work light on them to check under a load still nothing. The IDM is a reman from international, I would hope its good. This truck has been several places to be fixed and i've found bolts missing on brackets, just don't know if one got left off.

I'm using version Any help would be great. Is this a bobtail? Does this truck have an additional fuse box on the left fender well? Reputation: 1, Did you get a comp,eye reman idm or a half idm, as if you got a complete did the dealer program it for you cause the need to be programmed and parts guys are not always up to date on that? If all this is ok what codes are you getting after idm and fuse replacement?

Have you looked up the codes yet? The high voltage sticker is for the IDM, it puts out vac, and it will knock you on your if you mess around lol. I looked up the codes for ya; ECM, no errors detected, flash code only. I would really take some time to sit at a computer and do all the research you can.

More than likely it's an easy fix, but a little time behind a laptop will save you lots of money at the stealership. SemperFiServicesJul 12, JE Thomas Thanks this. Jul 12, 3. EHBJul 12, Jul 12, 4. This is an old 3 box system.

The IDM is mounted on the center of the fire wall. These are related to the ECM fuse blowing. I don't have my books with me at home.

How to program a comcast remote to a polaroid tv

I am going by memory here. I need to know which fuse is blowing, I believe there is one in the battery box and one in the fuse panel. The one in the fuse panel just goes to a relay at the firewall. The one at the batteries powers that same relay at the 30 terminal. If the battery relay is blowing you could just have a rubbed through wire shorting out.

The ECM is behind that plastic cover at the left side of the firewall. If you disconnect the ECM connector, big gray rectangular shape and the fuse keeps blowing, then you just have a shorted wire somewhere. HeavydJul 12, Jul 12, 5.Helpinout Active Member. USA Posts.

Cranks over fine but only fires with ether but will not run. Checked for fuel supply seems fine but still have to hook up gauge to reaffirm.

With past experience with similar systems I checked the high pressure oil and it reads about cranking. Trouble seems electrical and am not sure how to pull trouble codes.

Possible cam position sensor but don't have the money to just throw parts at it. Any help or suggestions would be appreciated.

Can you narrow down its location and what it looks like. Fuses were good at batteries but only one wire was hot at ECM. Pulled on the wire by starter to get it out in the open to test it and it pulled right out of harness. School Bus Fleet Magazine Forums. Helpinout Active Member 13 Posts.

Helpin-out at my church with a INTL bus that suddenly won't start. There should be a button under the dash next to the diagnostic terminal. I've looked all over for a diagnostic terminal but can't seem to find one. It won't look like an obdII plug, there should be a round Duesch connector probably six pins for that vintage. Found the problem, one of the power wires to the ECM was corroded in two inside the wiring harness.
