TPS connector harness; does it go between 1' and 2' injectors #1? Or in front of #1 primary?

I cannot find a snappic just yet here......

My TPS connector harness goes in front of first injector over the top of the PCV connector (and charcoal connector on 90') to Plenum.

I use blue and red Loctite where you are using grease on many of those bolts

Like Dyno says in front of first injector. Pic #4 page 1 and pic #11 especially. Looks like it was under the plenum vac tubes. Check those vacuum hoses to see if they are soft.

ed.: Cliff; Franke, you posted while I was looking at posted snappics, and Photo-Chopping BELOW... thanks.........................

Will be interesting how the paint scheme looks once put back together

Amazing thing; the cam still works after catchin' my mug in the lens!!!

Anyway, I found a snappic showing TPS harness in front of #1 1' INJ.

And I have a few vac tube routing / location errors here (at least)

And THIS is NOT how to put together your Z. Some others of ya' there must be ROFL'ing...

If this mill doesn't detonate when I pull the trigger, I'll be surprised...

OK - I got the 'tie' part, but which one in the Red circle over / under???

Someone has rerouted that line (lined one in pic) as it is supposed to be in front of the Pwr strg pump on the top of the clamp. Look at clamp and you will see nothing on top curved part. It follows the other vac line that goes to the front of the pump. Is that coolant pipe gasket on backwards?

Franke · 11-04-2013

Yes someone rerouted that line before you got it. Mine does go in front of the PS pump on the top of the clamp with the larger one on the bottom of the clamp. I suspect that at some point that hose was a source of a vac leak so the cut/splice easiest route method was embraced. While it will work ok it isn't factory correct and there in is the reason for the zip tie. No codes and I don't believe the hesitation source.

Schrade, What no spring ring clamps?

Look at page 1 #4 which shows the coolant hoses before removal. Maybe that will help ya as I see some markings on the hoses. Also, with the ignition off both of the fuel pumps are routed to the test connector through the fuel pump relays.

THanks again Sir...

I had P side 'marked', but the Trans-X swelled out the scratched-in mark. Stuff is amazing.

Those spring clamps leave a stinger in yer paw when they unload from pliers OuCH! And no way to rock the crossover and seat the hoses with OEM clamps on...

FP test tomorrow. Have to pull the sec pump fuse I suppose. And still need to do resistance check for the SP wires. That's where this part all started. No clue what spec resistance is on SP wires...

THEN... pull plugs. Put the Shop-Vac on 3 and try to pull the moth, if still in there. And I'm thinking rotate the crank 90', and pull 4, then 90' more, 3, 90' more 6, etc, to pull any jam that drained into each hole. AND, if I can figure out which hole is on the squeeze for each 90' pull, get a static squeeze check at the same time...

Time to start really thinkin' here... but I got dual exhaust if my CPU overheats from thinkin' too hard

Fuel pump test...

Pulling FP #2 fuse will isolate for pump #1 pressure...

BUT,

can I pull FP fuse #1, plug in FP #2 fuse, and isolate pump 2 pressure???
