so i have a 00 dc2 with fully built bottom block 2.0l and the car will start right up but when i drive it for a little when i turn it off... it hard to start just keep's cranking let it sit then after a while it will start and idea??

 

Have you checked to see if the problem is no fuel or no spark yet?

Fuel Pumps, PGM-FI Main Relays, Ignition Coils and ICMs, [ignition control module or igniter] are all susceptible to heat failure.

Start with the basics, fuel/spark, good consistent fuel pressure/strong consistent spark, do you have them? 94

 

your car could be dumping too much fuel and the sparks cant keep it, this happened to my friends car before.

 

This^^^ Either the coil or icm is my guess because of heat failure.

 

just put a new dizzy on the car and it still doing the same **** going to change the fuel filter 2marrow
