So i decided to do a compression test to see how the compression was holding up…turned out perfect 145 across all 4 but now when i go to start the car it dosent want to start…it will crank for ever but it seems to not be getting a spark…what are the main things that would cause this…and it dosent really make sense to me becuase it started up fine before i took the plugs out…and thats all i took out…anybody know what i could have missed or a little trick i dont know about? ---

Already did…i couldnt check to see if im getting a spark…im working by myself and have no one to crank the motor over haha…but now i tihnk im leaning towards it being a different problem…when i turn my key over to the on position my fuel pump dosent prime…i cant hear anything at all not matter how many times i turn the key on and off…any ideas? ---

mmmm thats weird, make sure that the wires pushed all the way in on the back of the ecu … also did you label the spark plugs 1234 when you removed them off the engine … also make sure the plugs for the sparkplugs are also tighten ---

(you might have bumped something doing the test) ---

(you might have bumped something doing the test)[/quote] i was trying to help … i remember when i needed help, it didnt matter how dumb it sounded i would try it to solve the issue which by the was doing an SR20 swap that granted some of you know that i got the wiring done at a shop but i was there the whole time trying to figure out why it wasnt cranking all the way … my issue was with the fuel injectors being clogged … but hey what i do know right … not everyone here is a nissan certified like you :roll: so save me the bs beside ur input to this problem was what … the cas sensor … did that solve the issue NO … that should tell you something
