Question = I Changed my fuel injector, it was leaking. I disconnected the fuel pump at the harness underneath the car. I put everything back together and now the car will not start. I Checked all fuses, the battery, the connector I disconnected to see if i bent anything. I replaced the starter. The cars fuel pump is working I can smell gas underneath the hood. When i crank the engine it clicks for one second then stops. It will not turn at all. There is no release valve on the fuel rail. I have pumped the pedal, tuned on and off the key to build up pressure but still nothing. I checked the fuel relay and still can not get any response. When I turn the key it makes a clicking noise and the lights in the dash flicker. I dont know why it wont turn. I have checked every thing and nothing is lose or blown. I have asked many people and they say its the battery but I know the battery is good. I really need help, thank you.
Answer: First off, a fuel system problem would have nothing to do with an engine that wont crank over. With the lights flickering, and starter only click / cranks for a second, this sounds like an electrical problem. Batteries can act very odd at times. They can test good even with a professional tester, but still have an internal short.
You may also have a ground problem. Maybe a ground wires left loose after replacement of an injector. Another area of ground problem is a corroded cable on the battery tray, While standing in front of the car, Check for a cable from the battery tray to the radiator support. It is only a few inches long and may be your problem.
Another possible condition may be that the leaking injector may have filled the cylinder with fuel causing a hydrostatic lock. Remove the spark plug of the cylinder you replaced the injector and look for it to be full of fuel. Again, batteries can do some weird things.
VISITOR: Thank you for your help. I have fuel in my head which has caused a hydrostatic lock. I am not sure what to do next. I wish I had some money to pay you for your advice. I guess I need to drain the oil to see if I cracked the head or bent a rod. Do you think my engine is toast. I guess I can pull all the spark plugs and let it air out. I dont know what else I can do to see if the engine turns over. Thank you so much for your help.
Answer: You can remove the plugs, crank the engine over as long as the ignition system has been disabled so you dont start a fire. Then let it air dry. An air gun is the best way. Then change the oil and it should start. Just trying to crank a hydrostatic locked engine should not do any damage. You should be OK
