Need help quick with compression test please

[ultrabaka]

So I have all the plugs out, I disconnected the MPI fuse, and unplugged the primary coil connector. Everytime I try turning it over for a few seconds WOT it still gives no reading on the guage. I followed all the instructions that came with the gauge and everything's screwed in tightly. Am I missing something here, because I don't think each cylinder should be reading 0.

Any suggestions would be greatly appreciated. I just don't want to waste money towing it somewhere (won't start).

It could red Zero if the Valves are fooked. check inside the spark plug holes for any Shit inside. you would also hear the Vavles Crunching up and shiznit. do that shouldnt be the problem. hmm, take off the Gauge. and just Listing for the Air comming out of the Spark plug holes. if there are. Then the Gauge isnt being put in right,

I'll try that. So I should listen if air is coming out when holding the key to the right? That'll take 2 people right? Also, should the clutch be floored as well as the gas or it doesn't matter?

umm the car wont turn over if the clutch isnt pushed in.

yah, the car wont crank with out the clutching being pushed in, Did you Remove the MPI fuse? You gotta Remove that, so There isnt any gas being injected at Wide open Throtel while cranking. yah, compression Test with 2 people are best.

Just make sure that the guage is working properly. Also "is the car running"? If it is and running well, then the guage is leaking air. If you have an air compressor put the # 1 piston on tdc and fill the chamber with 100lbs or so and litsen for air coming out of the exhaust pipe or the throttlebody. This should help......
