Its a obd2 distributer.

If the gsr don't have a crank sensor wouldn't I need a obd1 distributer?

I heard the obd 1 distributers have a sensor in them that sends a signal to the crank since it don't have a crank sensor.

That's what we were saying. Sounded like the ecu was looking, but isn't finding one. But since you're running an obd1, IDK. Sounds to be simple, if you're that close. I'd go back through and recheck the major stuff, especially.

Obd1 does not look for crank sensor I didn't think ?

Could it be the obd2 distributer not getting a crank signal?

Do I need the obd1 distributer if it has the Senor to check for a crank signal?

I haven't had to write this for at least a month, that's not bad..

OK, so let's get something straight before we all get more confused. All Honda engines have a crank sensor (which is often called a crank angle sensor). Some OBD2 Honda engines have a crank fluctuation sensor down by the oil pump, which is not the same as the crank angle sensor. The crank fluctuation sensor is not present on a lot of the JDM engines.
So all this talk about not having a crank sensor is crap. They might not have a crank fluctuation sensor. All of the OBD0/1/2 Honda engines have a crank sensor, and a cam sensor, because both are required to properly run an engine with sequential fuel injection.

The crank sensor is in the distributor on all of the engines. The ECU will not run the engine without the crank sensor in the distributor. The crank fluctuation sensor is what you're talking about. OBD1 engines don't have it, some OBD2 engines have it. And if you need to, you can bypass the crank fluctuation sensor input on the ECU but you'd do just as well running an OBD1 ECU.



By the way, Google "crank fluctuation sensor bypass".

Any ideas on why it wont start?

Sounds like its not getting ignition but all plugs get fire.

Sounds like its whining when it turns over.

If you're using the OBD2 ECU from the previous engine, the crank fluctuation sensor might cause it to not start, yes. You really should be using an OBD1 GSR ECU though (P72), because you'll need something to control the secondary butterflies (IAB system) on the GSR manifold (if you're still using the GSR manifold) and you're going to be able to need to do some tuning for the turbo setup (which is not possible with the the OBD2 ECU). If you have a different intake manifold, you can use a P28 or a P30 instead of a P72 and whatever you get will still need to be chipped and tuned.

Its obd1 Ecu. Already tuned and a aftermarket intake manifold. Even tried another obd1 Ecu still nothing
