anyone knows if i have to take out the dizzy to change the icm? this is from a obd1 b16 motor

and is a obd0 and obd1 icm the same?

 

you won't need to, but I normally do just to get a better angle at it in the bench vise.

just out of curiosity, is English your first language?

 

Make sure you have a timing gun to retime it or make a mark across the distributor and head with a sharpie so you can put the distributor back the way it was for timing purposes.

 

thanks for the tip on marking it..

would anyone know if the obd0 icm is the same as the obd1?

 

???

 

I don't believe OBD0 is the same. OBD1 and 2 are though. B and D-series are also the same. In some cases depending on what brand ICM you're using and what it came out of you'll need to cut down a couple of little nubs on the ICM bracket.

 

trying to get this car started after it was parked for the winter.

i 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

 

not sure what those readings are?....is the relay clicking when you turn the key? are you talikng about the fuel pump relay? maybe some piks would help.

 

pics of what?

new main relay
new cap rotor
new coil
new icm
im getting gas not getting spark
all my fuses are good
