swapped it around 2 years ago, car runs great till recently, came out of work and car would NOT turn on, solid CEL with no flash while checking code w the paperclip method, car would crank but not all the way, thought it was the dizzy because seen no spark, changed it and it didnt fix anything, once again CEL is SOLID, changed the main relay and ECU and it ran for 8 hours, then im driving down the road and car dies, car once again cranks but not all the way, what could it be?.. p s it is a OBD2 to OBD1 conversion
thanks,

 

check your grounds and all the connections in the obd harness make sure no pins came loose

 

I've ran into these problems a couple times while running just chipped computers. Everytime for me the problem was the chip had gone bad pulling it so many times and reburning it. I would change the chip out and they would be fine. I don't know if this will help your situation but if your running chips, its an idea.

 

did check the ground and connections in the OBD harness, have not done anything special to the car at all recently, its weird.... and yes it is chipped... along w stock fuel pump but w fuel regulator, just realized fuel pump fuse keeps blowing which is number 13 and 9 i believe, just finished replacing the new fuel pump which is a walbro fuel pump, will update tomorrow

 

update, so opened up the ECU its a p28 chipped, and capacitor c15 is burned, traced it and its part of the fuel pump, therefore i think the fuel pump did go bad and caused this chain reaction, running so far w a p28 w no trouble and its been 2 days, going to change the capacitor soon and reuse my old ecu, problem solved !!!
