can I get instructions to run a test on the ecm. Wont start. 2.5

Owner: For about $50.00 or less, you can buy an OBDII Generic scan tool @ an auto parts store, which is not a bad investment, plug it in & look @ data, while cranking you should see a RPM reading of 300 to 600, next check for spark by removing a plug wire & put a screwdriver in the end of the wire & position it next to a ground, crank and you should see spark, if you do, check for fuel pressure with a fuel pressure guage,or, end the agony and tow it to a qualified shop and get it fixed !
