I'm searching and not finding a whole lot of information.

DPFI Civic, will not start by it's self.. Only way I can get it to start is a little shot of starting fluid in the TB, then it run's and idles fine..

Just cranks any other time.

Any help with someone who has experience with these is appreciated.. I do not

 

Check your injectors.
There are only two.
The top one is your primary injector that should be running at idle and normal driving.
The secondary is the lower injector and should only come on under engine load conditions.
Sounds like maybe your primary isn't working and the secondary is taking over once you get it idling.

 

I've got a spare intake manifold laying around, I'm gonna pull the primary injector and give it a try..

Any other ideas or anyone experienced this?

 

take a test light and put it across the primary injector wires, to complete the circuit. crank the motor and see if it pulses while cranking. this will help narrow it down a bit.

 

Have the same exact problem as you on my DPFI CRX. just sent out the injectors to get serviced. it was sitting a long time so one assumption is that they are clogged from a few years of buildup. I'll update if this solves anything.

This is a great idea. Would have never thought of this to test current pulsing. Will definitely try this.

 

They are the only kind of Ideas i have...HAHAHAHA

 

Really difficult to see on multi meter and even test light can be difficult. you can get a NOID light at autozone for a few bucks to test if they injectors are firing on time. That still doesnt tell you if the injector is working though. Remove the injector while the car is running and see if its actually firing fuel.

 

DPFI has side feed injectors from the IM itself so sadly, you can not do this.
