55208, n00b at werk. Why am I not getting a compression reading? Posted by bullox, Jul-14-03 03:50 PM
That's right. After the bullshit I went thru yesterday, I didn't even get a compression reading. I just tried it again today, and the gauge doesn't even budge. My guess is that when I try to crank the engine, nothing moves, I can't hear anything move. So of course it's not cranking. I disconnected the two relays by the firewall, maybe they were the wrong ones?
Any ideas? I'd like to get a reading before the sun goes down tonight...(not much longer). any input would be much appreciated... __________ Chris 96 ESI 5 spd Milwaukee, WI

Well if it's cranking you should hear it.. Or just put your hand over an open spark plug hole and you should feel air coming out.
When I did my compression test I just pulled the spark plug boots and pulled all four spark plugs. Then I blocked the throttle wide open, had someone crank the engine while the gauge was in a spark plug hole.

hmmm. nothing was cranking at all for me. I pulled the two relays between the brake fluid reservoir and the clutch fluid reservoir. Were they the correct relays to pull?
I appreciate your input Jason. Thank you. __________ Chris 96 ESI 5 spd Milwaukee, WI

I'm not sure about the relays, but try this...
Put the relays back in and just pull all 4 boots of the sparks plugs. Then just lay the boots over the intake manifold so they are out of the way. They will also still have electricity through them so I got them as far away as possible and I'm stillnot sure if that was very safe, btu it worked. Then just crank the engine with all 4 plugs out and the compression gauge in one spark plug hole. Then check the other three cylinders.
That's how I did it and it worked for me.. Good luck

disconnect the 3 pin plug on the drivers side of the coil pack to avoid problems with shocking yourself with 47,000,000,000,000 volts
