1990 teg with obd1 b20/b16 swap
im still stumped trying to get this car started after it was parked for the winter.

ive changed the main relay/coil which was bad had rust on the metal part of it/cap+rotor/cables are good/spark plugs is good/getting gas/fuses are good.... just not getting spark.


anyhow i got my spare nec obd0 icm to fit in the obd1 plug and play/ just had to change the bracket that goes on it . still no start just crank.
i guess the icm is different on the inside.

also i tested the icms off the car and had the tester on auto since i dont really know about this stuff so bare with me if this makes some kind of sense lol ..


OBD 0 NEC readings

2.213 from right corner plug and right last plug

3.207 from middle plug and 1st plug


OBD1 NO NAME which was on my car (previous ower)

07.14 1st plug and middle plug

2.209 last right plug and right corner plug

 

Check engine light?

 

check light works normal with trying to start

 

does it stay on solid? If so the ecu could be bad

 

does not stay on works normal
