toyota corolla will not crank dashlights dim

What should I look at next? Is there some electronic component I have overlooked somewhere? I didn't test any relays because I was not sure that a faulty relay would cause an issue like this, am I wrong about that? Is there some other voltage regulator in my car that I don't know about? So I'm just completely stumped and discouraged. The ignition relay itself is often very cheap, and you can expect it to cost under 10, depending on if you want to buy an OEM original one or aftermarket. An ignition relay costs 5 to 50, and labor costs 10 to 50. but sometimes the car tony start I hear the fan and the dash lights all come. All fuses look intact, and all electrical systems are working. The average ignition relay replacement cost is between 15 and 100, depending on the car model and labor costs. If the engine will not crank over, the most common problem is the starter. I have tried individually pulling fuses from the driver's side junction block to see if removing any circuit made the issue go away (no success). (the reason I tried the above is that the issue seems to go away for a short period pretty consistently after I have disconnected and reconnected the battery) I even tried swapping in a new ECU (again, jy) I have tried swapping in a different relay integration (from the junkyard) But may I ask if you have a habit of driving with very low fuel, or even wait until very near empty before getting gas 5 people found this helpful. Other than that it may need an dealer or auto electrician. I have located all ground straps from the kick panels (under the dash) forward, which seem to all be tight and intact The advantage of this on a Corolla is you need only re-set the clock and not worry about radio codes. I have been trying to fix this for quite some time now, with no success. Test the Ignition Switch With the key in the RUN or ACC position, see if you are getting power to fuses 5, 8, 10, and 14. If there is power, you have a bad starter. Check the fuel pressure and do fuel lines check to track and diagnose the fault easily. It could also be a result of a weak fuel pump that can’t provide a standard pressure.

Check for a clogged fuel filter if the car dies while driving but restarts again. It's just really annoying, and kind of unsafe, as the headlights will completely go out momentarily and then return to original brightness (when the issue is happening of course). First, check the starter by turning the key in the ignition to ON and then using a circuit tester or voltmeter to see if there is power to the wires leading to the starter. To fix this problem, you must get a new belt and connect it to the engine pulleys. I have never been stranded due to this issue, and the car has never not started. Additionally: when I'm sitting in park with the car running, or sitting in drive at a light, and I put on the hazards, the engine will start surging (this symptom is pretty consistent). Sometimes when I hit the brakes, or apply the hazards/turn signals, some variation of my headlights/dashlights/clock will dim, but of course, it only happens sometimes (and this only happens when the car is running).

I have a great Corolla (1.8L DX Wagon) with a pesky intermittent electrical issue.
