I have a 95 tracker 1.6 L 16 valve. I started getting raw fuel out the tailpipe so I changed the fuel pressure regulator and no change so after checking with several sources I bought a new set of injectors and it fixed the problem and it ran great.......until the other day and it started losing power and had fuel out the tailpipe again. I pulled all the plugs and did a compression test and all cyl are 120+ and I noticed number one cylinder is spitting fuel out the sparkplug hole constantly. Ideas??
Sounds like your number one cylinder spark is not igniting the fuel. Unburned fuel is just spitting out of the exhaust. I assume the spark plug is soaked when you pull it out to check it? I don't think your issue is with fuel delivery, it sounds like an ignition problem.
Are you getting any misfire codes?
I pulled the fuel rail and hooked it up with the injectors out of the head and I have two injectors spraying nonstop when the key is on. When you crank the engine they keep spraying while the other two pulse. Ordering another set of new injectors tomorrow.
