Hey guys, I'm using my '88 IROC Vert for a daily driver. I came back from Walmart and parked the car. When I left for work that afternoon the car is running rough, Missing, No power. WTF ! Today I took it down to my freinds shop and found the vacumn lead for the heater control had fallen off. Put it back on, No improvement. Replaced the fuel filter (it wasn't clogged) and the cap and rotor. Still no help. Started pulling plug wires one at a time and the number 1 cylinder seems to be the problem. replaced the plug, wire ect. No help. Spark plug is firing. In fact, All cylinders have a nice strong spark. I unplug and replug the injector- no change. Is it possible that the injector just failed ?????????

Possible. Ohm it and do a fuel pressure test.

What should it Ohm out at? Supposed it's just stuck?


Also, What should the FP be? I forget. It's been awhile.

~15-17 ohms is average
43 psi static

You'd mostly be looking to see how well the pressure holds though. This will help to tell you if one of your injectors is stuck open
