2001 4runner SR5 V6 wont start. Truck recovered was stolen after 6 months. Whoever had truck put in new battery in July, found notice inside truck it was to be towed in September and from looks it hasnt been driven in months since,but otherwise in good shape... Tried to start wouldnt turn over just click noise. Replaced with new battery would crank but not start,same when trying to jump.Towed home, checked all fuses and connections, replaced fuel filter still no start. Checking and replacing if needed fuel pump tomorrow but also no spark yet either???.... Have good idea guy had a key but if he didn't, could it be my anti theft alarm system? I asked the dealership and they said "no" but not sure skillset of guy on the other end of phone, ... I see mention on other posts of ECM any ideas. I'm dying to get her back on the road !!!
