Misfiring and hard start

[3rdgen_4runner]

It seems to be taking more effort to start my truck each time. I know better not to just hold the key down. I just turn the key and tap the gas at the same time when it doesn't start immediately.

My thoughts of what maybe causing the hard start and the misfire is that it's either:

A) Fuel pump issue

B) Spark plugs and/or wires

C) Fuel pressure regulator

D) Burnt-out cylinder


I did notice what looked like a slight fuel leak the other day. But I don't know how to exactly to diagnose any fuel issues. So if anyone could assist me in the troubleshooting and possibly a low-cost solution to fix my hard start and potential misfiring.

Year & mileage would help. Any codes or CEL? Start with the easy stuff first. Check for fuel pressure. Easy test. Next move to make sure you have good spark, then compression check.

Why do you give it gas to start it?
