I've got this "roached out" 1992 Nissan Sentra I've been trying to get running. I'll try to make this as short as possible:
Compression wet test: 185,190,210,195 lbs
#4 cylinder has spark and injector is firing.
40 PSI of fuel pressure
Engine appears to be flooding out.
Check engine light flashes a code 13 which indicates a bad coolant temp sensor which will definitely flood an engine out if it's not sending anykind of reading to the ECU. When checked with an ohms meter, the sensor shows an open circuit instead of around 1600 ohms at 80F (well based on a Bosch L-jet sensor). Replaced sensor and connector. Engine still appears to flood out.
Pumped the 2 year old gas out of tank and added 3 gallons of fresh gas.
Still nothing.
So I'm thinking about installing a side draft 38mm Zenith S&S carburetor from a Harley Davidson I have laying around in place of the throttle body. All I need to do is fabricate a 3.25" X 3.25" plate and mount the carburetor to it. That's the easy part.
Then reduce the fuel pressure down to about 3 lbs. But before doing that I'm going to gravity feed it just to make sure it works.
My biggest hurdle is how to link the factory throttle cable to the carburetor. Or even link the accelerator to the throttle even if this requires cutting it down so it pulls from the opposite direction and fabricating something to go on the end of it.
The throttle body looks like this:
Here is what the carb looks like except it has a ball socket connector. However this particular carb has a similar piece that might work with the throttle cable:
I'm just wondering if any of you guys have ever done something like this if you can post some photos of how you did it so maybe I can get some ideas.
If I can verify this carb is going to work, I can cut down the throttle cable and attach someone on the end that might work.
