I have a 1973 Lotus Europa with a 1998 Integra GSR VTEC. No Start. The fuel injectors are not spraying. Here is what's going on.
- The Noid light is flashing which tells me ECU is good
- Continuity is good between ECU and harness
- Resistance is good between ECU and harness
- Spark plugs are new and tested
- Fuel pressure is good and getting to the fuel rail
- Injectors are new and spray when I hook a 9 volt battery to them and connect fuel pump to the battery

I really could use some advice. I don't understand what could be going on because the noid light flashes.
Any help would be greatly appreciated. Thanks

This is an awesome swap! You're best off posting on a Honda or Acura Forum specific to that era. Someone else can chime in with a link. Wish I could be more helpful.

Man what a great swap.
Bet that thing rips..
Has it worked at all since the swap?
was it running before the swap?
has the fuel pump been checked?
is there even a fuel filter on it? (that checked for clogs)

I asked a local builder I know that deals with GSR engines a lot. Hopefully this helps or you get it figured out soon!

Thanks for looking into this for me. I'm reading 12.08 volts at the injector harness. I'll double check it
and get back to you.

I’d hook up an oscilloscope to see the pulse it’s getting from the computer.

I'd have to think that posting this in a more relevant location would yield more informative responses.

I didn't do the swap but it worked great then the clutch blew and it sat around in Florida weather now trans but npc start. Injector4s are working and they are getting fuel but not firing. A noid test says the eco is putting out a pulse but they'r not firing. Can't fight it out. Here 's a pic of the motor. Let me know if you have any ideas. Thanks.

Curious .. how did you get to the conclusion your injectors are not firing

The plugs were not getting fuel so I removed the injectors with the fuel rail attached and attached a nine volt battery to the injectors and they fire. The injector ground is attached to the ECU and the hot wire to the battery. The ECU ground pulse tells the injectors to fire. When I connect a Noid light to the injector harness it flashes like it's getting a signal so they should be firing but they are not. Their must be an answer but I can't figure it out. Any thoughts?
