El Supracabas- i marked everything and put the crank at TDC and marked the CPS and then put everything back together the same way.
And yes its getting to be frustrating....it needs to be on the road so i can cruise around with the targa off on these nice sunny days!!
I finally got to the open circuit relay...but how do i test it to see if it is good?? because my fuel pump still doesnt prime the fuel rail before i attempt cranking the motor.

Ok, just checking. Would have been nice if that's all it was, it's very common. I am in agreement with cre regarding the use of ether on EFI engines, however I'm running out of ideas for you.
If you think it's not priming, jumper the fuel pump from the diagnostic box. Then try to start it. Have you checked the voltage at the pump while someone cranks the engine? The procedures to check the COR should be in the tsrm.
Here's an interesting read that will hopefully help you understand what you are looking for.

Well it started up yesterday. ran today. but now it decided to do what it did when i bought it. after driving so long and it gets to temp. the antifreeze empties out thru the overflow bottle. SO PISSED!!

I dont even know what to do now....
But on the other hand, Cre and El Supracabras have been extremely helpful...Thanks Guys.

Glad to help.
For the benefit of any readers who may stumble upon your unfortunate situation, would you mind posting what it was exactly that eventually got the car to start? I sure would like to know.
Take a little vacation from the car and go back when you're fresh to deal with the coolant issue. Old cars (mk3 supras!) can be frustrating. My supra has taken a healthy chunk of both my patience and money but I love having a car that people will look at for a couple minutes and still ask me "what kind of car is that?". Unfortunately it is usually followed by "you're leaking coolant".

could be a faulty rad cap, if its old or the seal on it is messed up it wont maintain pressure.

chuck0960 · 06-11-2011, 02:39 AM

its a new cap as well as thermostat.
Someone before me put that liquid glass stuff in it. U can see it in the radiator fins. So i am thinking that might be clogging the radiator and not letting the coolant circulate...causing it to become hot and take easiest way out.

The problem was that my CPS wires broke out of the clip so I had to wire them up around the clip and I had two of them wrong....dumb me.
Well today I bypassed my heater core...and it still emptied out the coolant through the overflow bottle....sux.
The only thing i can think of would be is that my block is cracked...it doesnt happen until the motor warms up. Is there a possibility that it could be my radiator??
I do need to take a break from it and then return later..but I want to enjoy it so bad. If the urge is to bad i take it down the street real quick and back before it can heat up and spit the coolant out.
