Default 1994 Chevy s10 4.3 TBI won’t start when warm

My truck starts up fine no problem while cold, but as soon as it gets warm and I try to start it again it just cracks over and over and usually takes me around 5-10 minutes to get it started again. It only does this if I’m let’s say running errands and I’m in and out, but it’d it’s site for a while then it will start back up fine

Here’s what I have changed:
distributor
cap and rotor
iac
rebuilt TBI
O2
fuel pump

When it does not start - do you have ignition?

My 94 did this due to a broken ignition control module ICM on the distributor. It would even run fine when warm unless shut-down, then it would not restart until cooled down.

I done some more digging and doubt out it was the ignition coil, replaced it with an ac delco and now it fires right up

Coils usually just go open or short, and usually just die. In fact I had one quit on me while driving through one of the worst neighborhoods in Newark, NJ while on the way home from the airport. Luckily, it was only 10 degrees F outside and the local denizens were inside like a bunch of cockroaches.

A coil is one of the spare parts I always keep in the truck, so once I figured out it had no spark going to the distributor I just pluged in my spare and I put the coil on the intake until I got home and bolted it in.
