240sx not starting

[j3w1z]

My 240sx cranks up but doesn't start.. this all happened after I installed my short ram intake.. I might of accidently loosened an electrical connection.. either than that I dont know know what might be wrong with my car.. It isn't my battery nor my starter, so what else could be the problem?? ignition coil?

check to see if your sparkplugs spark when they touch ground. I'm not sure about the safest way to perform this test.

this article covers this.
