about a week after i put my ported S4 manifold back on with new injectors my car wont start. it'll turn over but nothing is happeneing. i replaced the apark plugs and it started up but not after that. so im taking the manifold off and looking at my injector plugs and two of them have the plastic things around them broken off. think this could be a reason that its not starting? they bump loose or something? i cant get my right leading plug in all the way either. i know thats not helping either but if its stripped im pretty much screwed right? back to the injector plugs, can you replace those without a new harness otr what? i would do a compression check but dont have one . can i pick one up at any auto store and how much do they cost?

 

Do a quick search- replacements for the injector connectors can be had, and somebody posted this link for replacements

Simple compression testers can be had for under $25 at your local auto parts store...
