Just installed lots of new parts on this late 04 6 liter HPOP, Stand pipes, nipple cup orings, head gaskets. and now she wont go. Just cranks. Doing an air test now, should I be able to hear anything form the oil fill tube? It builds oil pressure just not right away, I did have an icp code. but has gone away as of now (p2285). What's consider a long crank time?


Thanks for any advice.

 

What's ICPV reading? need 520 psi and .85 volts to start

 

not more than 10 sec then let the starter cool down a bit, say 7seconds then rest 7 seconds then rest, need to purge air out of the system then it will build pressure.

 

You probably want to crank it like this with the key off. Easier on the injectors and FICM. When you suspect the air is purged, go back to the key.

Look on the passenger side near the heater fan motor and locate this connector. Coming back toward the front of the truck, it has a single wire inside the plastic sheathing that will be yellow with a blue stripe.



Squeeze the round connector like this to unlock it while twisting and pulling. It should unplug fairly easily.




There is a single pin inside the front half of the connector.




Touching this pin to the positive battery post SHOULD cause the starter to spin over and crank the engine. If you still have the factory battery terminals, this little bolt sticking up seems like it was made for this purpose. If it doesn't crank, there is an issue with the batteries, starter, or the electrical connections between them, or the engine is locked up due to mechanical failure or a cylinder filled with fuel or coolant. If the key is off it will only spin over, if the key is on it should start.





This shouldn't cause any significant sparking when you touch it to the battery and it shouldn't get hot while cranking. It won't hurt the truck and it won't hurt to drive it if you started it this way just be sure to reconnect it after it fires up.
