This is really starting to annoy me....

For the pass 8 months Ive had code 10 for my tcu making my S light blink. Also everysince this code has been flashing, I am having a hard time starting after letting the cb sit for so long, usually like 4 hours or so. I have changed so far:

Fuel Pump
Fuel Regulator
Water Temperture Sensor (front water neck)
FITV
Sparkplugs
Sparkplug Wires

From my own personal expieriance I did a wire test on the connector, going to the Water Temperture Sensor, and one is getting power, the other is grounded. I also replaced the connector. Some symptoms that make me think sumthing is wrong is that, after turning the key 15 to 16 times to get it running, its fine, But as soon as I get it crunk, it idles like its warmed up wen the cold/hot needle is still showing cold. My car idles at 600 during the warm up period basically. I replaced the water temp. sensor, reset the tcu and ecu and still no luck.

But as soon as I get it crunk

Maybe your car doesn't like to get crunk? Have you checked the ecu or tcu to see if there are any melted spots on the board? or swap it with a known working ecu?

Went to the junkyard to get one but no luck, im going to try this tho,

does the car have trouble restarting after you have driven it???..if so, check your main relay..when they got hot they become a pest..and if it hasnt been replaced, id suggest replacing it.

as for the S light, means the tcu has picked up a problem. id do a code check..what code is that s light throwing?

Did you even read the first post?, I specifically said that I have trouble starting it after letting it sit for a while, not after driving it. Its nt my main relay in other words, and in the first sentence I explained that the code that was being thrown by my tcu in CODE 10...

If it won't come out of sport mode, odds are, your tcu is shot. My wife was having the same issue

D5 looks like an ecu pin?

is it on the tcu or something? and but could my hard stop problem have anything to do with me grounding my amp on the same screw as my fuel pump
also which sensor is bad?

the one by the thermostat?

the one under the dizzy?

or the one on the water neck?
