We have a firetruck that is causing us a problem.  We're a small volunteer department. We bought new apparatus on a used chassis a few years ago because that is what we could afford. There is a company in Alabama that specializes in these.  We bought a tanker from them several years ago and have been very pleased. This chassis was a rental (Ryder I believe).

The 4700 wasn't here very long before it developed a couple problems The simple one is it seemed to be losing power. The big problem was the engine quitting or the truck not starting.  Took it to the IH dealer west of us (We're halfway between 2 of them) who replaced the high pressure pump, throttle position sensor, etc.  The next time it failed they were covered over so we had it towed to the dealer east of us.  They found a bad wire and had us up and going in 2 hours!  This winter it started losing antifreeze into the oil.  In frame overhaul and it's back going.  I drove it home, backed up to the firehouse, and it died.

It started right back up but that made me a bit apprehensive. Yesterday we had a kitchen stove fire.  Firefighter started the truck and went to put on his gear (SOP for us).  Truck died.  Cranked like there was no tomorrow, but would not fire ... kind of like pulling the coil wire on an old Chevy. 

Typically when this happens the driver cranks it until the batteries are down, so we either jump it or put a 110 volt charger on it.  After the batteries get back up it will usually fire right off.  So to me it seems it is very sensitive to low voltage. Talking to IH service and one of our firefighters who is a mechanic they seem to think the varous computer components should not be that sensitive.  If it has the juice to crank well it has the juice to work right.

One possibility throw out is a bad electrical connection or wire.  Giving the voltage just a little boost is enough to overcome the resistance or bad connection and get things working.

I need ideas.  Replacing it is not a possibility as this time.  We are still a year or two from havng it paid for.  Even if someone gave us a new chassis it has been estimated it would take $5-$10,000 to get the aparatus switched over  (This is one where the pump is driven by the main driveshaft.  When pumping the truck will not move).

Anybody have experience with a 4700 with a 466E that can point me in the right direction?

I don't know that it has a single solenoid.  I runs a high presure pump into a common rail system. One thing I am going to check on I found mentioned in a couple forums is a screen in the fuel system

I'm not convinced this is the problem but it looks like something we need to check anyway

I spent the afternoon crawling around and under the truck looking, disconnecting and reconnecting.  I thought I had it.  The cables in the battery box had some corrosion inside the connectors, especially the ones the 14 gauge wires to the ECM went to. (see photo below)  I cut the wires, cleaned them up and soldered them to a new 3/8 ring terminal. Along with 3 other guys we looked and poked and prodded and decided maybe that was it.Truck fired up ... for maybe 2 seconds then died.

May I pause here and say grawlix was not the term used at this time.

One of our guys called a friend in Indy who is a diesel mechanic.  His suggestion is it sounds like a crankshaft sensor.  He says a camshaft sensor would probably let it run, just poorly.

We do not have the equipment to reade error codes.  We're more or less 50 miles to the nearest dealer.

Ideas?

THANKS!  One of the problem I think we have is the 466 has been around a long time, but there have been different versions. So "Yeah we had a problem like that" may not be doing us any good.

I have to get some "Honey Do" stuff done this morning but may spend the afternoon with the red beast again just tracing wires and checking connections and a couple other ideas. I'm beginning to think we are chasing 2 or more different gremlins instead of just 1 simple problem.

Yesterday the Chief decided to pump the hand primer before trying to start it. (Why? Haven't a clue.  Just thought it might be a good idea.) Fired right up and ran for 15 minutes until the shut the truck off. So ... Did it really make a difference, is fuel leaking off, did he bump a wire while pumping it, did raising the hood shake a relay, is there a pressure sensor either failing or indicating a real problem,... this could make a bald man pull his hair.
