Where is best location to check fuel system pressure on 90 Civic PGM-FI (dual-point throttle body inj., SOHC)? Any suggestions would be most appreciated. I see some previous posts on this but no replies. [This was also posted in the Honda \ Let's Get Technical Forum] Thx - Ed

right at the end of the fuel line, where it bolts/clamps onto the throttle body... you can put another piece of line in there w/ a schrader on it, that will allow you to check fuel pressure.

Right at the top of the fuel filter, there is a bolt that screws into the top, unscrew it and put a gauge on it.

FrodoGT & DrOpZOn3,
Thanks for the reply posts. The smaller tap point on the filter connection was nestled in amongst the hoses & I missed it. I appreciate the guidance.
Before I had a chance to test fuel pressure, my buddy & I did some checking by dribbling gasoline down the throttle with the fuel injectors disconnected - and the car started, after being down for 6 mos. Checked everything else for no-start (fuel, spark, timing, compression, etc.). Turned out to be bad/contaminated gas. Strangest episode in my 25 years of working on cars!
Thanks - Ed

lmao, yeah that can happen... try using that gas w/ some good gas to clean the engine out, or just use it to start fires randomly... either way, good to see you got it running
