ok after a record setting time of replacing a knock sensor we cant get it to start up now. we know we are getting air and spark, and fuel to the rails. question is...can i bench check my injectors? reason i ask is because 2 of them had cracked plastic around the atomizer.

here is a link showing the work, if anyone can spot a skipped/missed step please tell me. any help??? thanks

Silly question: Do you have the VAFM plugged in?

injection /coolant temp sensor or as toyota calls it "Coolant temp for efi sensor",on coolant sensor bank near firewall.
Mine was shorted and truck would not start it would sputter periodically but would never fire up. do your self a favor and just go to your dealer and order one and put it in here is the part number 89422-20010 SHOULD BE $60.13 list
also there is the injector time switch that is a big problem when it fails
part number 89462-20040 $152.

so i went out to have a look see at the injector time switch and sure enuff, one of the leads is broken. once removed it fell apart in me hands. i guess thats why i keep coming back to these forums, cuz i never would have thought to check that. now after i order one up lets keep fingers crossed that its the problem. thanks fellas

Dude , In the video your intake and throttle body are facing the passenger side . My 3vze is from the drivers side WTF!!!

You can put those sensors in with out removing the plennum but you must be very carefull pulling the socket off I broke my first one after installing it and went to pull the socket off and it broke the plastic connector right off.
Take the heater hose out of the firewall mounted bracket and pull it towards the front of the vehicle this should give you enough room. Also climb up and lay on the plennum it will give you the best view and help you get the socket out straight.
Hope everything works out

It was weeks of no start before I figured it out so I hope I helped you!!

This is going to sound strange but my EFI swithch PN 8946220040 is broken off at the connector and the only problem that I am experiencing is that the electric fan doesn't run. I don't know if it is related to be broken switch or not. Any ideas?
