If you spark and fuel but only run when you spray starting fluid then you will need to check to see what the fuel pressure is if its too low the car will not start. also check the fuel injector/s to see if they are being operated. this is a fuel problem of some sort.

SOURCE: engine turns over fine , car will not start.

well the first part of your question i was all ready to tell you to put a new fuel pump in, now not so sure, there is a relay for fuel pump, can you hear pump cycle and relay click? relay under hood you will have to listen close they don't run long maybe a couple secounds, if you don't relay bad. if you do pump could be bad, do fuel pressure test pump could be weak. don't think sunroof and turn signals are related, but stranger things have happend.

SOURCE: crank no start: has no spark and only has injector

Fuel pump, you have to have press in the rail to fire all injectors- she will run on ether but not good for her. Ck your pump and any related fuses,relays,wiring.

Check the injector for 12v on one wire. if good check the other wire for a ground witth the key on. The ground wire pulses from the ECM If you dont have 12v from one wire to the other but you have 12v from one wire to battery ground then be sure the ground wire is good to the computer. If you don't have 12 v at any time check for open hot wire or bad fuse. ADD 12v to the hot wire at the injector. DO NOT add to the wrong wire or you will fry the computer

SOURCE: car cranks but wont start

replace your injectors. your vehicle is getting the fuel to start from the starter fluid. however the injectors arent giving it the gas that it needs to stay cranked

SOURCE: no power to fuel pump car was running fine just

Check for 12 volts power at the fuel pump harness. If no power is going to the pump, check the fuel pump relay. Also, check the fuel pump inertia switch. Ford usually has it on either inside left or right rear trunk fenders.

If the engine fires up for a second or two with starting fluid then the fuel pump is weak.I would check the fuel pressure and if its not within the specs then replace the pump and filter.

starting fluid is a thing of the past. dont use it. this car doesnt have a carb, its a throttle body/ electronic fuel injection system. you most likely have a fuel pump or fuel pressure regulator issue. test the fuel pressure, should be anywheres from 35-50 psi

Car has gas but won't start. Sprayed starter


the most likely reason is a failed fuel pump, plugged fuel filter or defective fuel regulator-you need to have the fuel line pressure tested-you can get the use (free) of a guage set from most commercial auto parts stores.

So we would have to assume from what you're saying that the injectors are not being pulled to ground by the computer. Have you tried listening to them with a mechanics stethoscope? The computers are a common problem but if another one gives the same result then I'd have to say that the wiring harness between the computer and the injector is suspect. You will have to check the continuity between the injector plug and the connector that goes into the computer. You will need a wiring diagram but I think the wire colors at the injector should be the same as they enter the computer. I would strongly suggest that you confirm fuel pressure though. I know what you mean by fuel at the injectors, but pressure is important.

well you narrowed it down to a fuel problem. not sure about your model, but most cars have a fuel pressure regulator on the fuel rail to reduce un needed pressures. that could possibly be bad. its cylinder in shape and has a vacuum hose connected to it. check the hose and that unit.

Won't start. turning, but won't fire.


If you think its fuel, spray some starter fluid inthe throttle body. If it fires up, you have a fuel problem, otherwise, check your spark plug wires, distributor cap and rotor. Also, check your fuses.
