I put my obd0 b16a (motor only) in my 93 del sol. I switched everything over to obd1. Now the fuel injectors aren't working. It cranks, I have spark, and I am getting fuel to the intake manifold. I also tested my main relay(its good) and replaced the blown #18 fuse. what else could it be? what else can I check?

 

did u use the OBD0 injectors that were in the b16?

 

which injectors? resistor box? Are you sure they aren't firing? can you smell fuel by the fuel rail after you try to crank it a few times?

 

I used the obd0 injectors that was in the motor. it is the same plug other than a little plastic piece that can be shaved off. I used the resistor out of my 90 crx si.

 

I have fuel at the fuel rail w/pressure

 

i would start with a set of obd1 injectors...

idk if im right but obd0 injectors might not work with a obd1 harness...

 

did you have to change the dizzy in order to change it from obd 1 to obd 0?? if you did you might want to make sure that you dont have the half moon of the dizzy that goes into the intake cam 180 degrees off. This happened to me when i put my motor in. My car turned over...was getting spark and fuel but wasn't starting. You might want to try this!!

 

all obd0 hondas/acuras use peak & hold syle injectors that are low resistance injectors that are measuered at 2.5/3 ohms (measured at 43 P.S.I.G.)

all obd1 hondas/acuras ( with the exception of 92-96 preludes) use saturated injectors that are high resistance injectors that are measured at approsx. 12-16 ohms ( measured at 43 P.S.I.G.)

u need obd1 injectors a.k.a. saturated injectors

 

you can run obd0 injectors as long as you have a resistor and it is wired for it. the last guy had a crvtec with peak/hold

I also found this:

So, which should I choose?

There are a ton of factors involved in this.
First, power level. If you're going big, there simply won't be a saturated injector that will support your power level. The largest common saturated injecotrs on the market are 550cc, with 440cc being a common "cap" in saturated size. Most boosted people run peak/hold setups for not only their availibilty, but also their ease of upgrading later on if so desired. simply swap the injectors. no need to re-wire again.
How is your car wired? most obd0 civics and some preludes are wired for peak/hold and have a resisitor box already. No point in changing to a saturated. Obd1+2 civics, and most other honda/acura cars after 1992 are all saturated and are not wired with resisitor boxes. Again, if there is an injector availble in your power range for flow of your car's design type, there's little sense to change.
Price. DSM eclipse/talon 450cc peak and hold injectors fit honda rails and with just a minor modification plug right in. best of all, these can be had for about $50-75 a set of 4 instead of $350+ for a set of aftermarket injectors. Add a $25 resistor box from an obd0 civic/crx, wire it up, and you're good to go in you're saturated car.
in a later article, we will cover the injector resistor box install procedure.

 

I have power to my injectors but no ground pulse!

I was just about to say make sure they're grounded. I believe they're grounded on the thermostat housing.

 

Put the injector wiring back to stock and buy my OBD-1 b16a3 injectors. 35 shipped.

Just pulled them out the other night for some tunertoys 450s. They work great
