No start when hot..?

[vrfour_nz]

Anyone had a experience of crank but no start when hot,no fault codes..ECU & ISC is in great condition..thought I had a fuel pump problem but it tests fine. Runs a chip similar to keydiver with stutter,055 afm,560 injs. Maybe thinking a sign of the No 1 TDC sensor failing?

Check your coolant temp sensor. Most likely the cause. There is a test procedure but it eludes me at the moment.

Very common with the temp. sensor. Just look for any faulty or haggard wires that may need replacing on the t-stat.

Had a try on it today again..left battery disconnected and went back to it. Starts cold then after a few minutes of running turned it off and it will not start again. I've now tryed another water temp sensor,afm,crank sensor,tested fuel pump pressure with the checker terminal. The wiring is in great condition. Any other suggestions?

This is a wild card shot but takes less than a min , Start the car when it is cold then disconnect the fpr vac hose and check for a fuel/smell or leak .

Is that youre coolent temp sensor right there in the upper rad. hose?
Because the stock one is low on the t-stat, and is not the sensor on the direct top. I believe that is for ac.

What the hell is that thing sitting on the charge pipe? And what is that hardline running up to the fuel rail area from it for?

My guess would be a catch can and a vacuum line.

^ Not that. The valve in the bottom left.

That's the antilag that he posted about around 6 months ago.

Quoting Adorsey:

yep i know..replaced the ecu coolant sensor on t-hsg,not the fan switch on the adapter

Do you have a data logger? Knowing that the ECM is seeing the temp sensor would eliminate the sensor. It could be a broke wire hidden under the insulation.
