Howdy Gang,
searching for the answer til my eyes were getting crossed so I'll ask.

1987 22re 5 speed 4x4

flooding -not running

compression test 150-210-210-200

plugs on 2-3-4 had a lot of gas in the cylinder
replaced the pressure regulator
still flooding

replaced the 15 year old injectors with reman units
cleaned the intake manifold
back together started and ran for <1minute rough

pulled the plugs and last 3 still have lots of fuel on them.

Is there a flow chart somewhere on troubleshooting the fuel system?

I'm trying to find a longer 8mmx1 banjo bolt to test the fuel pressure.
thanks
hank

Pulled the 4 wire o2 sensor out today and it was black and covered in soot.
I'll replace it with a new one and see if it helps.
