I have a 2009 Ford Edge. The starter will crank for about 1.5 seconds and the engine will begin to turn over but then will abruptly stop (as if electrical to it has been suddenly shut off).
I have checked the battery and all is good. With the key on off position I jumped the starter to bypass the ignition switch and it spun freely, indicating that the starter/solenoid is function when it is receiving consistent power. What it seems like is that it doesn't have the power to turn the engine over, or that perhaps a sensor is tripping and making it so that the electrical system is immediately killed part way through the start.
If I hold the key in the start position it will crank and then immediate die, after about 3 seconds it will repeat for as long as the key is held.
Is it possible there is an issue with compression and the starter is not strong enough to keep turning so it dies? But would it then continue on with the same pattern shortly after?
One fuel injector was leaking and the engine was running lean and it was having a difficult time starting but would always eventually fire up. Now after replacing the injectors it won't start at all. Could I have exacerbated a problem by replacing the injectors?
Looking forward to hearing your tips! Thanks!
