i have a 90 hatch with dpfi

the fuel pump is hot wired to a switch, the cel comes on right when i turn the key (power on before the starter switch)

i tried to bump start it by towing it for 2 blocks in first gear but it just wouldnt go on its own.

my buddies 91 dpfi hatch was there so i swapped ecu's to check it and his lit up with a solid cel in my car, but both ecu's worked fine on his car.

any ideas would help me greatly. thanks guys.

Weird...both ECUs light up solid in your car but are fine in his.

I'm not sure what to tell you...

Let the fun begin Good luck man. Hunting down problems like that is alway's an adventure.

ok, i fixed the solid cel. the negative battery terminal was missing the smaller chassis ground. i ghetto'd one up real fast and no more solid cel. no codes at all, but my ---- still wont start. gonna try towing it in first again

do i get free knuckles now? :P

im still getting a solid cel when the fuel pump is off, but i get no codes when the fuel pump is on, so i tried to bump start it again with no codes, fuel pump on and i still have a car that doesnt run. i'm about to just sell this as a shell... ----. *any ideas guys? im out of them atm. thanks.

who ever had the car before me pretended to be a wireing master. already had the dash pulled so i pulled the heater core all air ducts and sound deadening material i found like 3 wires worn and just twisted together. i soldered them all up and i resoldered everything in 3 of the main relays that i have. im still stranded... ill keep y'all updated though
