If you have no spark how can you say the coil is good?

SOURCE: cranks over..no spark or injection

I believe you are on the right track. E.C.U. or relay.

could be crank sensor

SOURCE: No Injector Pulse

run fault codes as there is a problem sensor in the system. volts at the injector is suspect as the voltage will vary with the fuel requirement.

Testimonial: "It's not throwing any codes. I was just sitting at idle and the car stalled. It didn't give me any indication at all that something was wrong. I tried to restart it and it just keeps cranking and cranking."

1998 ck2a lancer 4g15 no go. have replaced dizzy, computer and tps. has spark and injector pulse and timing is fine. any help appreciated


the next thing to check is the fuel system.
is there fuel in the system, the tank, fuel lines. is there fuel pressure at the injectors? check the fuel pump electrical system, the fuse, fuel pump relay, fuel cut off circuit. some factory security system have a fuel inhibitor, that disable the fuel pump circuit!

The dash gauges all work , fuel pumps are both good , the fuel pumps wont come on and the truck trys to fire when i turn the ignition on but wont , could this be a fuel regulator


did you check the fuel pressure pump on the frame rail for power and ground? have you verified no ignition spark to the spark plugs? have you checked for fire from the coil to the distributor cap? does the check engine light come on when you turn the key on? have you check for injector pulse and power at the fuel injectors? if the fuel pump won't come on and you have no ignition fire and no injector pulse, all of these systems are triggered by the ECM.

My 2001 Saturn, will start but not stay running. We have checked the fuel pump and all fluids. Did a compression check this morning, fuel injectors are not injecting fuel into fuel rail. Why is engine...


You said, 'fuel injectors are not injecting fuel into fuel rail' but it's my understanding that the fuel rail gasoline is supplied by the pump, and the fuel injectors just pulse to allow fuel to get to the cylinders. I would check out the fuel delivery problem further. Check for pressure in the fuel rail that is within specs.

If not, then the pump or fuel pressure regulator may be the problem. Check the fuse for the fuel pump. If good, then the pump may be bad in the tank.

Good luck on this.

There is no simple answer, there are to many variables. If you have access to a scan tool, pulling the codes should help. Without them its back to old school hunt and peck method. At this point we need to narrow down the problem. You need to test for spark.
  1. Tag and disconnect the spark plug wires from the spark plugs.
  2. Remove the spark plugs and install the spark plug wires to each spark plug.
  3. Ground (do not hold spark plug) the spark plug; check if spark occurs while engine is being cranked.
Crank the engine for no more than 2 seconds at a time to prevent flooding the engine with gasoline.
If you have spark, You will want to make sure you have fuel injector pulse, along with fuel pressure. If you have spark ..simply spray some starting fluid in through the air filter and hold the gas pedal to the floor and crank it over while spraying. If it fires up, you know it is fuel related( fuel pump, regulator, or ECM if no injector pulse) . If you have no spark then look at ignition coil connection and trace through to the distributor( if equipped ). The crank shaft sensor has a tendency to fail on these as well. This should give you a few things to test and check to start you on your way to narrowing it down. If you have no spark then look at ignition coil connection for power and trace through to the distributor( if equipped ). If it is DIS( no distributor). It may be the Crank sensor or the ECU. The crank shaft sensor has a tendency to fail on these as well.
The ECU uses the signal sent from the Crank sensor to trigger the spark and fuel injectors. ( make certain you have checked all fuses)

If you are getting spark and the engine tries to run on starter fluid, then you have lost fuel. Check that you are getting injection pulses at the injectors and check the fuel pressure at the fuel rail at the injectors. Check for power to the fuel pump when the engine is cranking, If you get no power to the fuel pump when cranking the engine, check fuses and relays. If the pump is running but you have no fuel pressure, check the fuel filter and fuel pressure regulator and replace any that are faulty. If the injection pulses are missing, check the supply relay which supplies power to the injectors first ( the injectors are earthed by the ECU) Disconnect one of the injector plugs and using a test light (buy one from a auto parts store) clip the end to a good earth on the vehicle body, switch the ignition on but dont start the engine, then probe the two connections in the injector plug. One of these connections should be active all the time with the ignition switched on. If it is, you may have a sensor failure (crank sensor etc), if it is not, check fuses and supply relays. A word of warning, the wiring you are dealing with is connected directly to the engine control, if you make a mistake, you can cause irreparable damage so if you have any doubts, take the vehicle to a professional..

91 ford mustang 5.0 fuel pump and relay is working but the pump is not getting power


How do you know the fuel pump is not getting power?.The fuel pump only comes on for a second or two before cutting back off.The ecm only suppys power to the relay for a few short seconds with key in the on position.Only constant 12 volts is supplied when the engine is running.Is the fuel pump new?How do we know it is good?Also is the engine giving a spark when the engine is turning over?If the engine has no spark,then the pick up coil could be bad,otr the ignition module could be bad.Check the fuel at the injsctors or a fuel line to see if the fuel will pump out when the key is turned on,if it does not,then check to see if the ijectors are pulsing.If the injectors are not pulsing ,and you have spark,then remove the distributor and replace the pick up coil,and the ignition module.The pick up coil,along with the igniyion module give the injectors there pulse.One other thing,If the fuel pump is not for sure coming on,check to see if the relay is clicking on,and then off in a couple of seconds.If this is true,then replace the fuel pump.Any other questons,please ask,I will try to help if I can.I hope this was some help,let me know,thanks.

I have hyundai accent 2003. While driving the engine died. Checked fuses,ignition,fuel pump(don't know if the pressure is right),starter is starting ok.


#1. Scan for trouble codes. If any, record them and let us know which ones they are.
#2. Connect a fuel gauge to the fuel delivery line at the engine... try to start the engine while monitoring fuel pressure... if there is fuel pressure (approx 35 to 50 lbs), the problem is elsewhere.
If no fuel pressure, check fuel pump relay, fuse, wiring to fuel pump connector (power & ground - use 12volt test light). If power & ground are present, problem is the pump (fuel filter is attached to the fuel pump inside the tank).
#3. Check injectors for injector pulse, check ignition coils for spark to spark plugs.
