Taking Bets on CRANK/NO START

There should be feedback from all 4 O2 sensors. However the 2 post-cat sensors won't show a trim value, because they are only used to monitor the cat's performance. The 2 pre-cat are used for mixture control, so will apply a trim value. If all was running well, I'd expect the fuel trims on both banks to be similar.

Your inlet vacuum seems to low. It should be around 29 in HG not 29 mm HG. That could be a simple display error on the reader.

Thank you. We have different books apparently, lol.

Reason tells me if I unplug something and it works better and if I plug it in and it dies, that it is faulty... But searching through the forums I saw that when people unplugged their MAF, they did not lose throttle response. This made me reluctant to think it was the MAF itself and that removing it is overriding/negating other data inputs to the computer.

Nevertheless, the mechanic had the MAF on backwards, somehow lost my retaining clip, lost a red clip for the pvc pipe near VIS. I wouldn't doubt if these idiots were spraying starting fluid in the engine through the MAF or something. But so far you've been dead on... The fuel pump was stuck, injectors were not firm when I received it back from the mechanic. I'd be willing to throw the parts you suggest at it now haha.

Nevertheless, I took off the MAF to clean it, ended up snapping an electrode off one side, so I devided to try to start it up with my modified (LOL) MAF. This resulted in ****ing off my Landy something aweful, she revved up, died down, revved up, died down, revved up.... for maybe 10 attempts before dying.

This was further evidence that the MAF was bad, considering I got a different reaction when busting off the electrode.
I tried busting the other one off, too. But that gave me the same results as having them both on.

A new MAF is in the mail and will update as soon as it comes in.

Thank you

Ah the mm HG was not the readers fault, my brain reverting to the standards I used in my academic life.
Thanks for pointing that out.

The MAF sensor came in yesterday and I hooked it up today.

It took a couple attempts to for it to fire up and idle.
Throttle responsive. However a tap on the pedal threw the RPMs high and lingered before coming down. (at idle)
Put it in drive and it died under load.
Started it up again and put it in drive and gave it gas,I was able to drive it up and down the block with throttle response for the first time in a year lol.
When I came to a stop it died.
Started it up and came back home but it jerked between gears, and now it took a lot of throttle to get a response.

Pending faults:
misfire 1, 2, 3, 4, 5, 6.
Bank 1 too lean
Bank 2 too lean

Looks like I'll need to rent the fuel pressure tester again and test under load now.
It's either the failing pump or an air leak (I noticed today that this idiot took my new gaskets off and used that 'create-a-gasket' paste)

Questions:
What would make a tap on the pedal throw the RPM's high and linger before coming down?
Is the filter inside the pump on the 2004?

I know very little about the V6, but could it be the Throttle Position Sensor?

If you are getting a lean mixture on both banks, then the inlet plenum has an air leak. You mentioned the red coller clip was lost. That could cause an air leak into the plenum. Basically all air that enters the inlet, must be measured by the MAF. Is air is bypassing the MAF, a lean mixture will be flagged.

I don't consider your "mechanic" to be a mechanic at all. A monkey could do a better job by the sounds of it.
It sounds like you need to check the everything carefully.
Good luck

Oh. The fuel filter is part of the pump. However I suspect that the problem is air leaking into the inlet. I'd discount the pump for a bit.

Thank you for your response, GrumpyGel. However, the TPS is responsive to different stimuli suggesting it's downstream.

@Nodge, You are correct:- If he is a mechanic, than I am a monkey.

after my previous post I realized that I had to turn it on and have my foot on the gas a little to idle and then put it into drive and keep my foot on the gas to keep it going (it seemed the faster it was going the better it performed). If it was the pump, I should have observed the opposite as the demand increased on the pump. I was going to rule out the uncertainties (gaskets are on the way) before I started fiddling with the pump.

You said "Bank1/2 too lean" is indicative of plenum leak... turning my deductions into sound diagnostics. I can't thank you enough for that.

I will update after gaskets arrive.

FREELANDER FIXED

It turns out the ''mechanic'' didn't remove my old gaskets. he just slapped on that gasket paste on top reassembled. The gasket didn't seem to be fitted flush as I remember doing it the first time (i could see a small part of gasket peeking out above the bolt holes) Nevertheless, I scraped off the gunk, wiped with alcohol and put the new gaskets on.
Not only did he break the red PVC clips but he broke the PVC itself near the VIS. I fished out the broken piece of PVC. I then reshaped the unit it with a razor to fit into the hole. I also put new O-rings on a few of the PVC holders at the front of the engine.

I had to fit the intake manifold twice because I forgot to plug int he fuel injectors at the back (hehe)

Cranked and fired. Had a shaky idle until I cleared the codes and now its purring like a kitten.

I drove it up and down the block a few times and then in my ally where we have a small rain ditch. I did a little mudding (not really mudding, though there was mud)

It seems a bit sluggish on acceleration but the computer may be learning how to walk again. t I drove it around the block and mini-mudding for about an hour with no faults or codes.

I even brought out my Porter-Cable dual action polisher and started doing some detailing. I will post some pics when I am finished.

Thank you Nodge and others for your help and support.
