I have no other lights on the dashboard or anywhere else that will come on. Only the Check Engine light comes on when I put the key in and turn it. The check engine light goes off after a couple seconds. It was running fine but over the last couple days it started to die occassionally when at idle. We replaced the IAC Idle Control Valve and after a few minutes of driving the idle went back to normal, that was yesterday morning. Since then everything has been fine. No check engine light, no idle problem, nothing. The vehicle has 112,000 miles on it. Within the last week it has had the spark plugs replaced with bosch platinum +4, the wires replaced, new serpentine belt, k&n air filter, Transmission Filter and fluid replaced, New Fuel Filter, New Brakes and Rotors, New Control Arms, New Lower Ball Joints, New Tie Rod Ends, New Stabilizer Link Bolts, Power Steering Fluid Flush and Fill, Coolant Flush and Fill, New Headlights. This vehicle has always ran great but now it is a second vehicle and we had the time to get it serviced for the 100,000 Mile checkup. The only problem we had been having was the motor dieing occassionally at idle which made the check engine light come on for the first time. We keep it serviced regularly and always have since it was new. Any help in this matter would be very much appreciated since now after doing routine maintenance it wont even start. Something else my brother took it to a car wash and used the tire cleaner on the motor to clean it for some reason yesterday morning after installing the IAC Idle control valve, but it ran fine yesterday and today till this afternoon. Do you think any of this could have any bearing on the current problem?
I already checked all the maxi fuses and ignition relay as well as both the cooling fan relays. I made a mistake earlier when I said I had checked the starter relay, I had not becuase the relay I checked and already swopped was the Ignition relay not the starter. I have yet to locate the starter relay but will do some digging in the morning to find it and rule that out. Even if the starter relay was bad would that stop everything else from working. I cannot even lock or unlock the vehicle with the remote. Nothing electrical with power works, no lights, no locks, nothing. The only thing now working is the check engine light when you turn the key and only a couple of times since this started I have heard a ding when I insert the key. It did start up after it had not started up once and I let it run for about 10 minutes and decided to shut it off and try to get a odbII test read on it but once I shut it off it was like someone turned the light switch back off because nothing would come one again.
