Hi guys, my 88 5KTQ used to start first shot in -40, unplugged (not that i did that intentionally, but there was times when i forgot).

Last winter, it had a hard time starting in -40, so I'm thinking there may be a problem with the CSV. Does anyone know which sensor the ECU reads off, when it decides to fire the CSV? I replaced the 1pin one, but perhaps it runs off the MFTS..?


I'll put an LED across the CSV and see if it is infact being trigged.. if i can't get it going, maybe i'll just throw a "prime" switch on it this winter, until i've got time to rig a proper controller...

thanks!

Try runing the ECU test and see if the CSV will cycle on and off.

Go to the following link to learn how to perform the test<ul><li><a href="http://www.sjmautotechnik.com/trouble_shooting/nostart.html#coldst">cold start valve test</a></li></ul>
