I know that there are not too many their 2L-TE specific but there is some overlap. Stuff like how to test the VSV and start relays etc is.

Toyota recreates a lot of the same sys in different vehicle models.

I test out your theory today. You've resolved the source of the problem.

This morning my Prado wouldn't start. The out door temp was 2 degrees. I did the same routine. I tried to doulble up the glow time.Nothing.

I took a ohm reading on pump speed sensor and it was open.(no continuity)

I put a 100 ohm resister in place of the sensor.Wouldn't start.

I jumped out that lead directly. Wouldn't start.

I had to pour hot water(only option) carefully aound that sensor. I put my meter on it and it started open closed at around 4000 ohms. As the heat sank into the pump the resistance rapidly fell off. In a few seconds it got to 100 ohms.

I quickly replaced the lead to the sensor and started it.Right away!!!

THANKS THANKS THANKS!!!!

I've been missing work,stranded and leaning under a hood for at least 40 hrs in this weather since beginning of Dec!!!

I knew it was temperture related and it is directly under the rad hose that lost its clamp.

My idea ...A- get a 12 volt heat gun or the like.

B-test out wiring a 2 pole momentary switch with
a variable resister in an atempt to bypass the fault
C- find out if /how to replace this sensor

Do you know how/ if you can replace this? You have one coming I
think.

Many thanks again,

Kirk
