Yes that was me, I am still having the same issues, I am expecting a new crank position sensor today, and i'm replacing the IAC valve as well, from a 90 LS400 that was wrecked last week. as soon as I get those replaced I will be checking the timing, the timing belt and water pump are 4 months old, so I hope I can get this done. If anybody has an more suggestions please don't hesitate. thanks
Tonyw,
Did you get your car fixed when you changed out the IAC valve? My car had similar problems as yours. I changed the fuel ECU, the fuel filter, ran Seafoam through the gas tank, and have been filling up on Chevron Supreme with Techron. So far for the past few months, I have been able to start my car each time. However, it is a little odd, but my first start sometimes acts likes it almost won't start but when I let go of the start switch the eng catches and runs without any further problems. All subsequent starts are normal. Haven't been able to figure it out, but since it runs fine I haven't thrown any more money into the car. Been thinking it was the cold start injector or circuit, just a guess.
For history purposes, my car snapped a timing belt, so I had the timing belt, water pump, plugs, wires, caps, and rotors replaced at the same time. Then the problems started. The car wouldn't start like it used to...... and the rest is what I just mentioned in the earlier paragraph.
No I have not gotten mine fixed, I can't fiure it out, with a fresh battery in and on the first crank it seems like it wants to start, it turns over runs for second then dies. I don't know.
