teh year I dont know, but it has the mds solenoids, and no VVT, so it must be between 03 and 09.

I replaced every sensor with the ones that came with my truck, same goes for the intake and injectors.

I did not connect the exhaust yet, and it is smoking very heavy, as if the injectors are all wide open.

I checked the injectors and not one is leaking under pressure.

My scanner comes up with, 'multiple missfires'

I cranked it today with WOT to clean out the chambers, and there was no fuel injected doing that, so thats OK.

Hi MDS didn't come out until late 2005 on cars and 2006 on trucks. So the engine would be at least a 2005. I looked up the timing set and the crankshaft (this is where the tone wheels are) and the part numbers between the truck and car engines are the same for 2007. At this time we need to know exactly what year this engine came out of. Is there any way that you can research and find out? If you can find a VIN number stamped on the engine anywhere, post it here and I can research it for you..

Does your scanner come up with any other codes than the multiple misfire codes? Can you post all the codes that are coming up? This may help...

Keep me posted...

Thank you,

Robert

I pulled the (new) plugs today and they weren t giving any spark and completely fould with tar. I think the guy I bought the engine from put some oil in the cambers for conservation, anyway, cleaned the plugs and and the cambers with some alcohol and it finally came to life.

Drove it for 5 min and now a P0706 comes up, *Transmission Range Sensor.... , and all gears are lit on the dash.... any ideas?

Expert:  Robert R replied 9 months ago.

Cool, Glad you got it going...

on the po706, check the transmission connector, try disconnecting it, and inspecting all the pins. If all are ok, reconnect the connector securely, clear codes and retest. If it comes back you will need to run the diagnostic procedure...

let me know if you need the flowchart for P0706

Keep me posted and let me know if you have any additional questions...

Thank you,

Robert
