Watching this one closely. My neighbor'* '91 LeSabre is doing the same thing. I was gonna start by checking the output of the IAT sensor with the ECT sender. If the computer thinks the car is warm when cold, then not enough fuel to go.

If either of you need an IAT, I've got a couple extras

if it was a faulty IAT it would set the SES with a DTC 23 of 25

Yeah but, it may be the IAT or the ECT sensor. And maybe one or the other can be bad enough (but not completely closed or open) to cause starting problems without setting a code?
