Who has broken in a brand new 2.7 3rz?

Verified resistance is within spec at 2150 ohms cold, regretfully I don't have an oscilloscope to check wave pulse

Do you know any other sensor I should check which is apart of the firing of this motor?

 

Damn, that's unreal man. But prolly just another day in the park for someone like that guy to have the engine replaced.

 

I would imagine the cam sensor cuts spark as well. Although I’m not 100% on that like I am the crank sensor

 

Hopefully someone knows for sure, but I would think that the cam position sensor signal would also be required for the ECM to energize the fuel pump

 

Yes, if you have coil packs then the cam sensor should be somewhere on the head. I think on the side in the middle between 2nd and 3rd cylinders.

Did you verify power to the coils? All related fuses good? Ground wire attached from head to firewall?

 

Even if the grounds look tight and all there I'd double/triple check them. You might stumble upon something else in the process.

 

Is the ground you're talking about that should go to the head? I thought it was wierd that it went back to the ecm connector

 

That goes to the head

 

There you go Abeyancer. Nice catch se7enine

 

Fixed it's placement and still just cranks


I'm starting to think maybe the machine shop didn't do the timing chain correctly... do I have to pull the whole timing cover to check the timing or can I do it with just removing the valve cover?

 

If the injectors don't have the testing lot numbers, just get them flow tested before you run them. You could have a perfect set or 1 to 4 could be under-performers. I bought a set of 6 (that turned out to be counterfeits) and had them tested before attempting to use them. I could not use two of them because they would not perform like the others. It just adds to the expense to get new injectors tested and to replace any found to be weak. You don't want to knowingly run a couple of cylinders leaner than the others -- especially on an engine that you intend to keep.

 

Thank you for your input I will definitely get them flow tested and see

 

All related fuses are good, fixed the ground wire going to the head. Will verify power going to coils tomorrow, I just need to search through the engine manual to figure out the values I need to test for..

Just to ask a silly question..... there's no way I could fuck up the ecm with just plugging the harness back into it correct? I guess I'm specifically asking if all the plugs are keyed or different enough I couldn't have switch something unintentionally. But it was late in the 3rd day of putting everything back in and I was tired and don't really remember that part of my process

 

@CS_AR if the timing was off it would still throw spark correct? Just at the wrong time?

I dont want to tear apart the timing cover to verify it's timed correctly just yet if my no spark issue is from something else

 

Usually yes. Spark would be some amount of degrees off resulting in a misfire. Check to see if there isn't something to do with timing externally that could be 180 degrees off.

 

I'm sorry I'm confused. What can I check externally? Or do you mean checking the two cams are times to each other correctly by just taking the valve cover off?

 

Do you have a distributor?

 

No sir, twin coil pack

 

Ok.. more modern then.

 

Yea... I miss my 64 econoline for alot of things but especially its simplicity, it had 8 wires in the entire wiring harness if I remember correctly
