To All,
Any help with this will be appreciated since my engine knowledge is limited. My son was in an accident with my LSi in November where he rear ended someone at low speed. Their rear bumper rode over our front bumper and crushed the radiator into where it was barely touching the engine. The air bags didn't deploy. I removed the damaged parts, had a new radiator support put in, and tried to start the car. It cranks but doesn't start. I can hear the fuel pump running if I'm underneath the car. Tomorrow I'll spend some time trying to figure this out. Any ideas will be appreciated.
1. I'll pull the fuel line off after the filter to see if there's pumping gas.
2. I'll pull a spark plug to see if they're wet (injectors) and if they have spark.
3. Is there an "accident relay" or "after emergency mode" that turns
something off in the ignition circuit when in an accident?
-Does the "fuel rollover switch" have a role?
-Does the security system have to be reset?
4. I'll check for vacuum hoses that came off (didn't see any) and harness
connectors that may have come off. The harnesses, at least in the
damaged area, seemed to be undamaged.
5. I'll look at ground connections.
6. The "ambient air temp sensor" looks OK but doesn't the ECU uses this
for air mixture? I assume I can just check the temp gauge in the car
to see if this works.
7. Are there parts that may break with impact that wouldn't allow the
car to start at all? -Mass Air Flow Sensor
-ECM
-Crank Sensor
Thanks in advance,
Dennis
