305 TPI Hard Start

this only happend occasionally usually after it sits overnight. It will take about 5seconds of cranking for it to start then it will stumble to idle, and i can somtimes smell alot of fuel. After i drive it around and shut it off it will fire right back up just by tappin the ignition, but there has been some times where it had trouble starting right after i shut it off to but very rarley. Has new plugs and wires. You guys have any suggestions

My moneys on a few leaky fuel injectors or a bad fuel pressure regulator. I had the same exact problem. A few of my injectors would leak when the car was off, flooding the engine. Next time you know it's not going to start good, press the gas pedal past half throttle and try starting it.

Get a rebuilt distributor, these TPI are known for hard starting. Ignition pickup and control module are known issues. Read the recall notices from years back....

I have an 88 TPI LB9 motor, and it starts cold like a champ. Like in 1 second, fires right up.

And it does have a reman dizzy, the original dizzy's bearings went south and the shaft started wobbling pretty bad. If you need a new module, only use genuine GM Delco, everything else is a failure waiting to happen at the worst possible time. MSD uses Delco modules in their remote coil dizzys.
