do compression test on a warm engine

yank all plugs , pull fuel pump inj fuse , disconnect coilpack , prop throttle body open , make sure battery is good or keep connected to battery booster

crank over about 5-6 cycles for each cylinder
you should read 150psi or so and none should be more than 10% off (15psi variation overall)
