My car suddenly shuts off while driving, I’ve changed battery, Fuel Pump Module, Fuel Pump Connector, Chassis Control Module, Spark Plugs but still the problem persists. All these diagnosis and repairs were done by the dealership but the problem still persists!

Sometimes, the engine starts working at the first attempt, but suddenly stalls. If I try turning it on again quickly, nothing will happen. I need to wait for some seconds and only then it will start working again. Everything has been checked, and even the coil and distributor's cover and connectors have been replaced. When this failures occurs, there is no spark in the spark plugs. Sometimes, the following day the problem disappears and starts working without any problems. I would appreciate your help.

Good afternoon, I have a Camaro 95 v6 3.4 and my problem is that, when starting the engine, it stalls. I've already changed the ignition key as, at the beginning, the security appeared on the dashboard. After changing it, the indicator continued appearing, so the orange wire coming from the ignition cylinder was disconnected and a resistance of the same voltage was installed, but still no change. New coils and their plates were installed and even the fuel pump, filters and spark plugs were replaced, but without any positive results. I really don't know what can be happening. Thanks for your help.

Turns over all lights it has that normally come on but I get no spark its something in ignition it's an lt1 5.7

My Camaro z28, 1997 suddenly does not start. The engine begins running but won't finally start working. Coils and the crankshaft sensor have been checked but everything seems to be alright. There is no spark in the spark plugs, and I was told it is the computer that is failing.

My son was going to try to jumper off the ignition switch to see if it would run but it… Vollständig lesen

There is no spark. I've already checked the optispark and crankshaft sensor and they are both alright. The coil and ignition switch are working properly just as well. What might it be? Does the crankshaft sensor send the signal to the optispark, then to the ignition switch and finally to the coil or how does it work?
