could leak be from cracked injector line or incomeing line that once it gets warm expands and allows air to get in the system

 

How would you find a leak like that?

 

Sounds like a wire is broke or a bad sensor. I have seen this on TDR where a wire was rubbing a pulley that made some people pull out their hare.===Go to the post that says everyone read this.

 

That is the wire going over the A/C line, passenger side motor. Sticky at the top of this forum. It grounds the 5v to the camshaft postion sensor.

 

yea the thing is that it runs good till it gets too about 200 if it was a short wouldnt it do it no matter what. as far as the leak get it up to temp and look or drive down a dusty dirt road and try to find wet spots on the fuel lines

reread the post could it be sometype of vapor lock in the tank caused by the warm fuel going back into it

 

could it be in the temp.control sensor.sending the ecm a bad reading that the engine senses a overtemp and starts to defuel. could you find the previous owner and inquire about the cut wireing. may be that what ever caused the internal failure, was a temp problem from maybe overboost. it sounds like it is defueling as a safety factor. might also check all boots on the air system, you could be loosing boost.

 

Can anyone tell me what the following should be conected to, these are on passenger side firewall:
1. Female plug with Blk and Green wires
2.Female plug with Red and Blk wires
3.Green and Green Blk wires cut just hanging
4. Broken vacum line


As far as a leak the only one I can find is it is slightly wet at the back of engine on drives side.

 

Sorry, I am trying to enlarge these and having no luck so far.

 

not a mechanic by any means...

but I am going with, bad temp sensor...telling the puter your overheating and to SHUT'ER DOWN....

my temp doesnt go over 190* as was stated eariler..

if it were a fuel issue, I do not see why 200* would have anything to do with it....an air lock, probally gonna happen once or twice by now at start up, at idle on a red light, might stumble on a right or left hand turn, if it were oil and fuel, probally gonna notice it at the tailpipe by now, leaky injector might have showed itself at start up as well, hard start syptoms....

it just doesnt sound typical of a fuel issue...

it sounds more like a TEMP issue, which leads me to think a bad sensor....if the engine overheated on the origional engine failure.. and the codes were never properly cleared...a fault might be stored on the puter, with no CHECK ENGINE light shown on the dash....I would clear ALL engine codes, even those tricky hidden ones...and start with a temp sensor...

NCA

 

Do you know where the sensor is? I have two wires that were cut and can't figure out where they go.

 

The temp sensor is near the thermostat...

 

had my truck at 220 and it didnt go into limp mode

 

I think it is either lift pump, EGR or a sensor just not sure. Looks like it will have to go to the dealer. I really appreciate everyones help. Thanks

 

I just looked at mine and it looks like your missing a part.
The red and black wires plug into a part that also hooks into the vacume line.
