It could be the engine immobilizer in the security system, try it with a different key, make sure it is a key with the transponder in it.

SOURCE: Ford Escort 1998 fuel pump not working.

good old ford lol, try looking at the crank sensor its located at the front of the engine tucked in right hand side of exhaust manifold and gearbox, two pin plug, i have also known these to have no end of faults with the fusebox.
easy to remove, and solder the connections inside they all suffer eventually, if your not to handy with cars i recommend taking to a auto electrician, easy if you know how. Good luck Davelee

Try spraying some carb cleaner in the air intake and see if it tries to run. If it does its a fuel issue. Either you dont have fuel pressure, or the injectors are not opening. What is the fuel pressure? should be approx 40 psi. Does the CK ENG light up when you turn the key on?

Hi! before I start, just want to say WOW! sorry to hear that you spend alot money and nothing changes happen. The best way to save money is to scan the car for diagnose, you can buy this scanner in any auto parts for about lowest $50.00 or more depends on there brand. Every engine requires four basic ingredients to start: sufficient cranking speed, good compression, adequate ignition voltage (with correct timing) and fuel (a relatively rich air/fuel mixture initially). So any time an engine fails to start, you can assume it lacks one of these four essential ingredients. But which one? To find you, you need to analyze the situation. If the engine won't crank, you are probably dealing with a starter or battery problem. If the engine won't crank or cranks slowly when you attempt to start or the engine (and the battery is fully charged), you can focus your attention on the starter circuit. A quick way to diagnose cranking problems is to switch on the headlights and watch what happens when you attempt to start the engine. If the headlights go out, a poor battery cable connection may be strangling the flow of amps. All battery cable connections should be checked and cleaned along with the engine-to-chassis ground straps. If you see a good hot spark when you crank the engine, but it won't start, check for fuel. The problem might be a On an older engine with a pump the throttle linkage and look for fuel squirting into the carburetor throat. No fuel?
On newer vehicles with electronic fuel injection, connect a pressure gauge to the fuel rail to see if there is any pressure in the line. No pressure when the key is on? Check for a failed fuel pump, pump relay, fuse or wiring problem.
On Fords, don't forget to check the inertia safety switch which is usually hidden in the trunk or under a rear kick panel. The switch shuts off the fuel pump in an accident. So if the switch has been tripped, resetting it should restore the flow of fuel to the engine. Lack of fuel can also be caused by obstructions in the fuel line or pickup sock inside the tank. And don't forget to check the fuel gauge. It is amazing how many no starts are caused by an empty fuel tank. There is also the possibility that the fuel in the tank may be heavily contaminated with water or overloaded with alcohol. If the tank was just filled,might be causing the problem. On EFI-equipped engines, fuel pressure in the line does not necessarily mean the fuel is being injected into the engine. Listen for clicking or buzzing that would indicate the injectors are working. No noise? Check for voltage and ground at the injectors. A defective ECM may not be driving the injectors, or the EFI power supply relay may have called it quits. Some EFI-systems rely on input from the camshaft position sensor to generate the injector pulses. Loss of this signal could prevent the system from functioning. Even if there is fuel and it is being delivered to the engine, a massive vacuum leak could be preventing the engine from starting. A large enough vacuum leak will lean out the air/fuel ratio to such an extent that the mixture won't ignite. An EGR valve that is stuck wide open, a disconnected PCV hose, loose vacuum hose for the power brake booster, or similar leak could be the culprit. Check all vacuum connections and listen for unusual sucking noises while cranking. If an engine that has fuel and spark, no serious vacuum leaks and cranks normally should start. but still no start? The problem is If it is an overhead cam engine with a rubber timing belt, a would be the most likely cause especially if the engine has a lot of miles on it. Most OEMs recommend replacing the OHC timing belt every 60,000 miles for preventative maintenance, but many belts are never changed. Eventually they break, and when they do the engine stops dead in its tracks. And in engines that lack sufficient valve-to-piston clearance as many import engines and some domestic engines do, it also causes extensive damage (bent valves and valvetrain components & sometimes cracked pistons). Overhead cams can also bind and break if the head warps due to severe overheating, or the cam bearings are starved for lubrication. A cam seizure may occur during a subzero cold start if the oil in the crankcase is too thick and is slow to reach the cam (a good reason for using 5W-20 or 5W-30 for winter driving). High rpm cam failure can occur if the oil level is low or the oil is long overdue for a change. With high mileage pushrod engines, the timing chain may have broken or slipped. Either type of problem can be diagnosed by doing a compression check and/or removing a valve cover and watching for valve movement when the engine is cranked. A may prevent an engine from starting if the engine is a four cylinder with two dead cylinders. But most six or eight cylinder engines will sputter to life and run roughly even with a blown gasket. The gasket can, however, allow coolant to leak into the cylinder and hydro lock the engine.
Well I hope some of this 411 will resolve your problem. take care & best of luck...

1993 mercury village engine was running was driving down road it shut down, check engine light was on , friend said to change fuel pump and still no spark at engine plugs, what should i try next? is there...


Fuel pumps don't have anything to do with spark. Have the codes read. My guess you lost the crank sensor, ignition module, or coil. Check your fuses also.

My 1999 ford expidition want start


Could be many things. First i would listen for the fuel pump to kick on whenever you turn the key on(without starting). Then if you don't hear it kicking on, check all your fuses. Especially the fuel pump fuse. If none of your fuses are bad, then your fuel pump is shot and you need to replace it. After that, if it still wont start, Check to see if your getting spark to your spark plugs. You can do this by taking the sprk plug out, and keeping it hooked to the wire and have someone try to crank the motor. As they are turning the motor over, see if you see the spark plug sparking. If not, then its your coil packs, or your vehicle is off time. ALSO, try changing the crank sensor. That could be why its not starting as well. Hope this helps, James Booth. Please rate this. :) And good luck with your experiance in trying to crank your vehicle. Have a good day.

2000 Eclipse GT turns over but doesn't start. Fires once in a while but won't run. Had timing belt replaced.


Hi, if the car turn over, and it don't start. Then it is like the engine don't get fuel. Or bad a spark plugs. Most common problem is the fuel pump going bad.

It could also be a bad fuse, but a easy way to check if the fuel pump is ok is to have someone stand at the back of the car when you turn the ignition. The fuel pump should make a buzzing sound for a few seconds. And if you don't start the car right away the fuel pump will stop.

If you don't hear any buzzing from the fuel pump/fuel tank then you have a bad fuel pump............

Cranks but wont start


you need to check for spark at the plugs while cranking.then check for fuel entering the intake at the injectors.you don`t say if its a 4 or 6 cylinder.if its a 4 cylinder you can look into the throttle body while someone cranks the motor and you should see fuel squirting into the intake.if you have no spark then check to make sure the cap and rotor is in good condition and the rotor is turning(if not then the timing belt maybe broken and needs replacing.also check the plugs as if they are worn so bad you won`t get any spark.a common problem on these is the coil pickup in the distributor going bad.there is a 2 wire connector that comes out of the distributor with a plug,if you follow this wire back into the distributor you will see the pickup.also check and see if you can hear the fuel pump running while cranking,you may have a bad fuel pump.you may have to remove the gas cap and listen at the filler neck or listen under the car were the gas tank is.if the fuel pump is not running then you can hit the fuel tank in the middle while someone cranks the motor and it might start.if so then the fuel pump is no good another common problem.there is a fuel pump relay under the hood on the drivers side that sometimes goes bad or there is bad connections.most of this checking is good for the 6 cylinder as well except you can see the fuel squirting into the intake.it could also be a bad computer that will have to be checked out at a shop.

CAR WILL TURNOVER BUT WONT START


if the car is turning over fast enough then you need 3 things for it to start,fuel/pressure,air no intake blockage/and spark.check to make sure you have spark at the plugs by pulling off a plug wire and have someone turn over the motor(be careful as there is about 50-60,000 volts) if you have spark then check for fuel and fuel pressure(pressure should be about 35lbs).you can also check for fuel pump operation as there should be a noise like a humming noise that you could here at the fuel filler neck with the gas cap off or you can listen at the fuel tank with your ear or a screwdriver held against the tank with your ear against the other end of the tool while cranking.if you don`t hear the pump then its not working.check the fuses in the fuse panel to make sure its okay.common problem with these is the fuel pump.

My 1991 lexus will not start when the ignition is turn with the key. The ingine constantly turns over without starting and preceeds to kill my batterie.


Well if it is cranking you need to see if you are getting spark and fuel.....Try turning the ignition on without cranking the motor....You should hear your fuel pump making a whirring sound for about 3 sec.and then shut off...If no sound from pump (which is located in the fuel tank) check the fuel pump fuse If fuse is good check fuel pump relay...If all checks out ok with fuel pump take into consideration when the fuel filter was changed last....I dont recommend adding fuel injection cleaner to your tank without first changing fuel filter...additive is designed to break up debris thus breaking up all trapped particles in filter sending debris through your injectors.... To check for spark pull the #1 spark plug wire and place it on an angle on tip of plug (allowing you to see if spark is present) have an assistant crank engine while you look for spark..... Do not hold spark plug wire in your hand while engine is cranked.... I hope this has helped you
