2006 Tacoma 1GR-FE Engine Swap

I'm suspecting MAF sensor and throttle body connections, would def clean both regardless.

 

That's not all that helpful, those could have been set by all the messing around that has been done or they could be current. Only way to know is to clear the codes and see if they come back as pending/current, also would be useful to see live data.

That doesn't appear to be an OEM MAF, might for grins unplug it and see if the truck stays running. It will be in limp mode but it should run with the sensor unplugged.

 

It’s not. I bought it yesterday since it had over 200k on it. I've tried unplugging it and started but stopped straight away. I plan on tracing wiring to see if there's a loose wire.

 

I'm trying to "not" drop the fuel tank to check for clogged fuel filter. Is there anyway to determine if this warranted beforehand, codes, etc? Also, my mechanic said he tested the fuel pressure and stated that it was good until it shut off.

 

Until it was shut off? As in it lost pressure immediately? It should be 40.8 to 41.7psi when running. When shut off it should remain above 21psi for 5 minutes. Per manual. Mine stays at nominal for at least 20 minutes after shutdown.

 

I did not see the test results. Before I go borrow a fuel pressure gauge is there anything else I can check?

 

Have you checked if the correct fuel pump relay is installed (should be a 5 pin) and the fuel pump resistor is plugged in?

 

I haven't check the fuel pump relay. I did bypass the resister, still same issue.

 

Would a clogged CAT cause this? This was a blown gasket engine and I'm wondering if some gunk is stuck in there.

 

Extremely rare to have one plugged so bad it would keep the engine from running and you have a V6 so both sides would have to be plugged solid, not saying it can't happen but I highly doubt it.

 

Get yourself one of these. This is one of the best options for DB9 bluetooth scanners. Use Torque app or similar. You can read real time data, pull and reset codes.

Damn!

 

Weird. Regardless, there's similar options out there.

 

Better options out there at that price point.

 

I was able to pick the below diag scanner and clear the saved codes.

I re-ran the diag and am getting the following codes:

 

Your in OBD monitors not codes, we want to read/clear codes (DTCs).

 

I've erased and scanned again. No error codes.

 

Does anything come back after a start attempt?

 

This is after the start attempt.

 

Can you go into live data and get us a few pictures of the current values?
Like MAF, ECT, A/F, O2.......

Just to see if anything jumps out at us.
