Just wanted to check with u all if u've come across this problem.
It tends to take a longer time to start up when the engine is warm. It doesn't happen all the time. At times the engine would fire up immediately and at times it would take bout 2-3 seconds before firing up. It doesn't happen when the engine is cold.
Hey oddball, as a matter of fact i've just (a week ago) replaced the coolant temp sensor. It might be a coincidence, but i didn't remember the long cranking before changing the sensor. Could the sensor be loose or somethin......
idle bypass?? is that the same as idle valve??
16vastra, I've also changed the fuel pump and relay not too long ago.
Best is to remove the ECU and mesure the temperature sensor from there. If it mesures within the spec then both the sensor and the wiring going to it are OK. If not check what went wrong when you fitted the new sensor.
Idle valve is also operated by the ECU through some wire harness. On a 8V is known fact that cleaning it will improve warm start a lot. I cleaned my recently but it comes back and misbehaves. I replaced my one with a second hand one and it seems to be still working fine.
I have had this also.
Have changed the ecu temp sensor a few times to make sure, and the fuel pump relay.
Pressing the throttle to the floor does help, but not a lot. Although starting mine takes about 4-5seconds when warm.
