Was waiting for a train today and suddenly the truck started to miss horribly, black smoke pouring out of the exhaust. The miss got worse and worse until the truck died. I had to restart the truck to get it out of the roadway and it didn't have enough power to move itself hardly.

The deltas are usually 5-8* max. Fuel pressure is 55psi, FICM voltage is 48.5-49v checked with my meter. HPOP pressure is around 800psi unless I"m misunderstanding something thats more than enough.

Now the truck won't start, zero smoke out of the exhaust it doesn't even sound like it's injecting fuel. I would say it was the ficm but the voltage reads good. I unplugged the ICP just to try and see if it was bad and the truck still turns and turns with no catch.

Any ideas fellas? I hope that I have enough information above. Oh running motorcraft filters and caps and delo 5w40 synthetic oil changed about 800 miles ago.

Just checked and when cranking I get lots of air in the fuel filter housing. I believe that means the o-rings on the injectors are bad correct?

It typically means an injector(s) are loose, or somehow the copper gasket(s) are shot.

the injector didn't seem loose. But now we have a bigger problem.

I put new orings on all the injectors and replaced the number 7 injector which is the one in the picture. Put it all back together and now I have 0 hpop pressure. I put new oil, and new fuel filters in it. cranks and cranks and I get zero pressure out of the sensor so I unplugged it to put the truck in default mode but still nothing.

Can I assume the hpop is dead? If thats the truth I'm just going to light the truck on fire and watch it burn. I've already put more money into this truck than what it is worth on kbb.

It's funny I had a 95 chevy with the 6.5 in it and it ran forever this piece of **** won't run for more than a week without needing 1000+ in repairs.

It could just be air in the rails. When I put mine back together, I filled the hpop resivor with oil and pulled the highest plugs out of the rails and filled them with oil before tryin to start.

Did you inspect your dummy plug and standpipe orings? And the torque on the standpipe is 60 ft/lb I believe.

Orings on the standpipes and dummy plug looked good. I torqued to 65ft/lb I thought it was around 60ft lbs but couldn't remember. Surely 5lbs of overtorque didn't cause the problem I wouldn't think.

I just put both batteries on the charger I'm afraid if I keep trying I'm going to end up killing the ficm with low voltage. I'm praying/hoping that I'm just not getting enough rpm out of the starter to make pressure is that possible?

The gauge on the dash moves so I know my low pressure oil is good.

Pull the icp sensor off the valve cover and spin it over, that will let you know if its oiling and get the air out. Be carful it has the potential of making a hell of a mess!

Did you fill the oil at the oil fill tube? Try pulling the filter and pouring oil in the housing to make sure the hpop resivor is full

it will generally take a minute or so of cranking for the one oil rail that was off to finally fill with enough oil to build pressure.

don't pull the ICP sensor off and crank, even 20 PSI of oil pressure will make a huge mess.

Ok after charging both batteries and what seemed like an eternity of cranking the
Truck runs. I think this one is going to go to market very soon I don't think the previous owner took very good care of it.

Ok after driving on the highway I now have a cylinder 7 contribution code again. I've got a brand new injector in there. I've been fighting with that specific one since I bought the truck could the ficm affect just one cylinder?

Yes, it's possible. How does it run and idle?

I might be wrong on this^^, I believe early my could drop single injectors. But , there was a guy here having a problem like your if I remember correctly, the nipple on the oil rail that fit into his injector had a nick or something on it. He ended up changing out the oil rail when all else failed.

Well when I first started it the truck idled perfect and drove great up until I got on the highway after 45mph it started to stutter and is loping like it's got a giant cam at idle. I guess tomorrow I get to tear it down again. I'm getting real sick of this.

Ok pulled the offending injector and the copper washer was trashed. I have a new one but I can't seem to get it to slip over
The injector tip. Like the inside hole is to small any tips?

It's supposed to be snug so when you install it, it won't fall off. There are small ridges on one side of the washer, I believe the ridges go down. Are you sure you got the old washer out from the first time? I think you can use the appropriate size deep socket to instal it carefully.
