what fuse do i need to remove before i m doing compression test?... i been trying to remove the fuel pump relay but i cant reach it and remove it.. and i did remove the ecu fuse but it s doesnt work that well... well i m kinda of afraid to do compression test because i did once long time ago i havent remove relay or fuse and it s start baammm!!!! with a kinda big fire out of spark hole i was really scare i really dont know what to do!!! ... so lucky it s didnt fire the whole car...my friend and i trying to get rid of fire... lucky it s was gone.. so right now i m kinda of afraid to do it again... i just need to know what fuse could i remove it ???

thanks

 

i was in the same boat as you, i was looking for a 15A fuse but there was no fuel injection fuse in the under hood fuses. Simply disconnect the distributor plugs. That will do it.

 

Just remove the fuse for the ecu.

No fuel will be squirted into the cylinders without the ecu. Also remove all the spark plugs and wires before you start to crank it over. I've seen people only remove the plugs/wires from the cylinder they are testing and the car started right up

just unplug your dist.

 

i unplugged each injector wire harness and removed all the spark plugs when i did a compression test last week.

 

I heard this is the easiest way, but you can take the other precautions if you want to be safe.
