No Codes

Recently my car has started to act up. In the morning on my drive to school the car is perfectly fine, very responsive, no ses light ect. However when i park the car go to school for about 3 hours or so and start it up again it dosn't imediately fire up like it normaly does. Also the SES light is on but very faintly, then it becomes solid and the car seems to have lost a considerable amount of power and is producing a smell that i've never smelt before. Two mechanics i've brought it to also had no idea what the smell was.

I've tried myself hooking up my laptop to the aldl port like i have before but get no data. Both mechanics try'd hooking up actual scanners to the car and didn't get anything either. So one try'd the jumper that grounds the aldl port to get the codes and didn't even get code 12.

The car is an 87 Z28 with a 350 TPI. Majority of sensors are new, engine is only 5 months old and has about 4k miles on it. Computer is 4 months old from NAPA and the prom is a custom burnt one.

Sorry about the long post but does any one have any suggestions?

Yesterday aftetrnoon the car stalled and ses light didn't even come back on when i put the key to run, so i assumed the computer wasn't getting any power. I messed around with some wires under the hood near the battery and it started up again but still ran poorly. I checked the fuse for the ecm. I checked the ecm connector, all grounds and power wires are doing what they're supposed to. Normally it's fine again in the morning but this morning it's just as bad as last night. It seems to be missing a lot also.

Any suggestions??
