Moms car. No fuel condition. Code 12. Swapped ecm. Checked grounds. Brother had it going but doesn't know how! A short time anyhow but overheated. Would not restart. Injectors operate by manually grounding blue ecm wire. Car is in ex condition. Seems the common thing here ties it to the temp sensor. ECM didn't turn on the fans. Could that sensor prevent the injector circuit from operating? Curt is at the ropes end. Need your expertice now. Promise not to bug you again..............not! Thank You!!
