update car just started after unplugging and plugging in tcu and the tempature has coold off by 20 degrees or so i think it is the main relay that was causing the problems no more s light blinking car drove fine again shut off and starts without problems now thank you all for your help getting new main relay tommorrow

1 - Lock-up solenoid 'A' circuit open or shorted.
3 - Throttle Position Sensor circuit open or shorted.
6 - Shift Lever Position Switch circuit open.
7 - Shift Solenoid 'A' circuit open or shorted.
8 - Shift Solenoid 'B' circuit open or shorted.
14 - Linear (line pressure control) solenoid open or shorted.


You have a lot of solenoids that needs replacing. I believe the reason it won't start because of the TPS.

alot of those circuits can be lead to just one or 2. I vote for tps. if the computer is seeing tps voltage out of range, what it thinks is that the accelerator is pushed to the floor. usually in GM cars its called clear flood mode.

disconenct the tps and start the car. it may run in limp mode, i think. all the shift solenoids and stuff will just prevent it from shifting correctly, but waht linear solenoid...i forgot waht that is...is that the egr circuit?

hey dude...your learning! Im not sarcasticly saying this, but dude your learning man thats cool.

[accordztech]

didnt see that last post.

Interesting. if it was the main relay then it wouldnt get any fuel.

unless the tcu is going bad internally. but humm, now im thinking.

if you need another tcu auto i have one.

yeah it could have been his contact point for for is messed up but he said he smells gas so that should be fine...but then he said once it was cooler he unpluged the tcu and replugged which like you said let it run in limp mode but can still be his main relay since the fact that with it being cooler outside the tempurature is down allowing th contact point to make a good contact again so if i was him id pull some cash together and buy a good relay and tcu and problem should be all good

The TCU is BAD replace it and all your problems go away.

alright guys the car is still running today i dont think the tcu is bad or going bad cause unplugging it and plugging it back in should not have fixed it when it cooled off last night it started just fine and its starting and running today so i think its just the main relay that caused all the problems yesterday thanks for all of your help i really appreciate it

still check your relay and replace and probally do the same for tcu...(preventative maintanace) because doing what ya did might have set the tcu in limp mode like said by accordztech i think

i try haha yeah thanks

hug me later.

hug me later.

haha what lol
