: 94 Seville intermittent hard start

Intermittent hard start (cranks for about 10 seconds before firing and starting). Sometimes after sitting for 10 minutes. Sometimes after 1 hour or 2 hours. Very occasionally in the morning. Must of the time it starts fine. Also, when car is started it runs fine.
This is getting frustrating to find the problem.

Could this happen only when car has been run and then sitting for about a hour or if the car has been in a heated garage?

My problem is very intermittent!

Maybe an intermittently failing fuel pump. Check the fuel pressure next time it happens.

Our 89 Buick just had this problem. mechanic changed the spark plugs, & wires, but most importantly, the fuel filter. He said our old filter was was so clogged up the car couldn't get enough gas to start up.
