PATS4LIFE Posted January 24, 2020 Author Share Posted January 24, 2020 I hope it’s not my immobilizer unit, But when I insert my key in the ignition the security light goes away so that means immobilizer is reading it right? Link to comment Share on other sites More sharing options...
Call me Q Posted January 24, 2020 Share Posted January 24, 2020 Loose battery cable? Link to comment Share on other sites More sharing options...
XT-sub Posted January 24, 2020 Share Posted January 24, 2020 it started right up but shuts off after a few seconds, Did it shut off as soon as you removed the jump start battery? A few things to check. With a voltmeter connected to your battery what voltage do you now read under the following conditions? (1). Without trying to start the car. (2). When trying to start the car. (3). With the jump start battery connected without trying to start the car. (4). With the jump start battery connected & trying to start the car. Are all your battery +ve & -ve cables making adequate (clean & low resistance) connection to your battery? It could be a high resistance intercell connector inside the battery going open circuit under load. Link to comment Share on other sites More sharing options...

It shut off while the jumper cables was still on and after that it would not crank at all even when I tried jumping it again, Battery cables are tight and clean. I will be picking up new battery this morning,since my stock battery needs to be replaced anyways. Link to comment Share on other sites More sharing options...

PATS4LIFE Posted January 24, 2020 Author Share Posted January 24, 2020 UPDATE:took stock battery to AUTOZONE had them charge it,well it wasn’t holding charge anymore,so bought me optima battery,hook it up and car started right up and let it idle for 15min then turned car off a few min then re started it but car shuts down again the turned key and no crank.So I was thinking could be my remote start causing it to shutdown so I decided to rip off my remote starter and bam car is all good again no shutting down..I guess remote starter crap out too:/ Link to comment Share on other sites More sharing options...

Good to know. would never have thought to look at the remote start, had this happened to me. Did you have the Subaru one or an aftermarket?

Did you have the Subaru one or an aftermarket? I had the Fortin Evo-one remote starter. I’ll probably try Viper remote starter next time. I must have fried the remote start module when I jump started the car. Link to comment Share on other sites More sharing options...
