i have an lt4 and i put it in the car the first time the car
did turn on but i let it sit for 3 weeks and now i go to it and doesn't turn on non of the two lights turn on either
could be tha computer that is **** up i has 2 lights1 yellow 2 red but non of them turn on i know hat yellow
has to blink but i forgot about the red one and i don't know what to do with it!!!!!!!!!!!!!!!!!!!!

 

ok check the fuse to the battery, if this is blown it wont turn on, also does the battery have charge in it?? and is the pink wire still connected to the IGN on??

i did check the fuse but i didn't check the pink wire
yeah u are right i am gonna check it but do those cumputer get **** up easy is it the same color on the lt4?????????????????????

 

hey dale i found another problem i have like three different pink wires i didn't find any pink wire by it self
but how many cables does that need 2 wires for example one red one black or uses 3 like the radios???????????? thanks

you have 3 different pink wires because one goes to the coils, one to the fuel pump relay, and another goes to the ignition power (key on, and STILL on while starting) I just went off the master relay for it. I'll figure out a better way later.

 

thats correct you have them for fuel pump relay, ign supply and coils,

The ecu's are very robust, they just dont stop working for no reason,
