On a vehicle with a electric fuel pump pull the fuel pump relay, let engine idle until it stalls out. For mechanical fuel pump, I think using a vise grip and 2 thin blocks of wood (to avoid crimping the soft line) on the rubber fuel line will work. This prevents fire hazard. | On a vehicle with a electric fuel pump pull the fuel pump relay, let engine idle until it stalls out.

Move onto the next cylinder, repeat the compression test, and when you're done they should not be more than 10% off from each other, and none should be really low (0). If they are, you have some problems. | Move onto the next cylinder, repeat the compression test, and when you're done they should not be more than 10% off from each other, and none should be really low (0).
