New fuel pump, pressure is good. New programed ecm, new delco spider. , still injectors are not emitting fuel. Starter fluid will fire the engine but won't stay running. Ob II shows no codes. Why?
My blazer still won't start, now all of a sudden I open the door and the alarm goes off. And my key fob's don't work. Could that be tripping something to stop the injectors from working?
Do you have a small automatic start stop door button and after market security system? I ask because my 97 Blazer was giving me same problem after changing everything out as I had it pulled test were fine on removed parts. Turned out being after market security system...I went under the dash on the driver seat by where my hood release handle and e-mailed break is undid the steering column or under dash found all the wiring housing units and I unplugged it through out that remote hadn't had a problem since.
I had the same problem on a 1999 blazer. Ihad to relearn the key several times,takes 30 minutes,each time i did it. I finly took steering colum apart and eliminated the yellow wire. Basicaly bypasses the security system chevy installed. Both these procedures are on u tube. Mine has been fine for over a year now,only bitch is security light is always on,black tape and i'm happy.
