Hello, I have a 1989 RS. 305 TBI and auto trans. 56K on it. Just bought it. when I bought it it was running rough and would not idle, then I could not keep it running by pumping pedal(gas). Well, I have REPLACED EVERYTHING. All engine sensors, the cap and rotor, plug wires, plugs, distributor module and Pickup, the coil, I even rebuilt the TBI unit. It cranks over all day and gets fuel spray from the injectors. Checked the static timing, it is right on with TDC. NOW the WEIRD part. It will not fire at all, BUT, if you remove the coil wire from the coil and hold it about 1/4 to 1/2 inch above the post, IT WILL RUN for a about 10 to 15 seconds and then shut off, but if you try to start it again while holding the coil wire off, It will start right up????? I have never seen this is 20+ years of working on cars. I even replaced the computer boix with a new one and it does the same thing. HELP???? Even the local Chevy dealer was amazed......

Check your grounds. Run a temporary ground wire from the negative battery post to the engine and from there to the distributor housing and see what happens. The newer engines have a lot of aluminum that is prone to oxidation. I use oxguard which is available at major hardware stores. Electricians use it to make connections with aluminum wire. I even use it on the battery terminals. It works great.
