im alright with this test i added oil and it moved up to about 196-200 each one or so again this is with the fuel pump still spraying (i didnt know how to disconnect it)

again i have 138k on this engine so i feel like its wearing pretty good

now time to spray the hell out of it tongue.gif

Not bad for so many miles.

To disconect fuel pump - simply take out pump fuse.

Mad_john

i think i will do one,btw where is the fuel pump fuse?

Box thingey in your engine bay... least I would imagine it would be there. Which fuse it is I have no idea. Webtech is your friend, go look there.

I didn't find a fuse for fuel pump, but I found a relay for fuel pump (it's under the hood). On the box there should be a mark - withch relay is for what.

where is this fuel pump fuse/relay? it's not listed too well on the cover. "b+" for example so if you could tell me what it is right next to or what it's labeled, it'd be great! also are you able to do a word search on webtech anymore?

don't worry about the fuel pump fuse, just disconnect the injectors

Dmitry

disconnect harness under rear seat

You dont want to disconnect the fuel pump. If you do that, the injectors will still fire without any fuel goin thru them to cool them down.

Compression test is a good sign of engine wear, you can also do a leak test. Adding oil will make a better compression test but won't improve the leak test. Also, if you have agressive cams, you will get lower compression figures.
