I have a 1995 turbo built block Ls/vtec integra.Ok so i drove to school and came outside to leave started my car and it started and shut right off about 3 seconds later. I noticed i dident hear my 255 fuel pump prime so i towed the car home but a spare fuel pump in and the car still wouldent start. I then put in a new main relay and still no start or prime so i checked the fuses everything good. I got the test light out and pulled the pgmfi fuse and the test light showed no power. Everytime i used to put my key in the on position the check engine would blink twice to prove im running Ectune. Now it just stays soild. ANY ideas please let me know im hoping to put another ecu in tomorrow to test

 

The ecu that may car with did the same thing (solid check engine light) but the car would still start and run albiet pretty bad. Id swap out the ecu as thats more than likely the problem. Good luck

 

You cant just "swap out the ecu" tho..
i would assume the car is tuned for the setup he's running, unless you go get it rechipped or retuned with the new ECU before you put it in your car, your car is going to run like crap. and probly still give you a CEL.

 

I didnt mean swap out as in put a stock ecu back in it. I would assume that he would either switch his chip over or get another one made for his setup.
