Compression Test Results. Need some help...
whats up guys, i have a bit of a problem... heres where i started, and where i ended up. im posting this in FI because i know there are alot of people with tons of knowledge, definitely way more than i have.
BONE stock b16(118,000miles ), intake, headers, straight pipe, p06 chipped (dont know with what, its not mine). the car was running fine (im assuming) until i noticed that i had a problem with my oil being burned. so i did a compression test. first time i screwed up and forgot to unplug the 15amp fuse for the fuel. therefore im assuming i flooded the cylinders with gas. after that test was done, the car WOULD NOT start.
the ECU i was using at the time is my friends p06 chipped ecu that was ran on a turbo setup he had, so im assuming its running rich. (the reason im using this ECU is because if i put my stock P2T ecu, i was running very lean because of my straight pipe and the 02 sensor feedback and all that junk)
so then i left it over night, came back the next morning, ran another compression test and here are my results.
#1-190
#2-185
#3-200
#4-210
my car still cannot start, i am assuming there is a problem with my ignition, i replaced my spark plugs too. also,
How do i know that my ignition system isnt faulty??
thanks guys, i know im still kinda new but my car is just sitting in the middle of burbank not being able to get started..

compression test is a little varied. thats not really the best. Did you remember to unplug the distributor. You may have burned up the ignitor inside. Just check for spark by putting a screwdriver in one of the plug wires, and then holding the metal close to something grounded on the car.
stick a screwdriver in the plug wires one at a time and crank the motor,if it shocks u on all the wires then its not the spark.stupid question but did u remember to remove and replace the ecu fuse?
Check all your work. Like the other poster said, check the fuse you removed and any other things you touched. You either don't have spark or you don't have fuel. You can do the screwdriver test to check the spark. Make sure you check at the spark plug and also at the coil. If you have no spark at the spark plug but you do out of the coil then you might have a bad rotor or both cap/rotor. If everything checks OK, you need to determine if it is getting fuel. An easy check is to use some carb clean by spraying about a 3-second spray into the intake (this will act as fuel). If, when you crank over the engine, the engine sounds like it wants to start or starts and then dies, then you have no fuel (or you're running too rich while cranking). To determine what could cause this condition, check the fuses (all of them!) of course, then from there the diagnosis may get a bit more complicated.
