Default fuel injectors leaking test?

I suspect that my injectors are leaking fuel into the cylinders when my 90 240 sits overnight. Is there an easy way to test this?

I took mine off and had a local machine shop test, clean, and then replace the seals. One of them was a leaker.

would leaking injectors cause a hard start after sitting overnight? The first couple of spins of the starter it acts like it has no compression (fuel washed cylinders?) then it gains compression and starts to fire only if I WOT then runs rough for about 10 seconds then runs fine.

Have you ruled out the issue being caused by the coolant temp sensor?

if fuel was leaking into the cylinders, you should consider changing the oil
