95 cirrus 2.5 won't start no spark. Turn key on fuel pump runs a for quick second the shut off. Not getting 12v to the distributor unless I jump the asd relay. Swapped the relay still the same thing. Put a new crank sensor in still no spark and no volts to the single green/orange wire. What should I check

I guess the question is, how do I fix my problem. My problem is, I can get the truck to start-up. But it won't stay running. It only 'runs' for like 1-2 seconds. What do I do?


Hi Mathew

Dont know your car or model.

But.... Some info may help.
Ignitions systems apply 12v to Start motor & often supplies 12v around a resistor (wire) to boost 12v to the coil then the ignition key rotates back to another position. Run.
This connects 12v to the ignition system / coil through a resistor to the ignition coil (reduced) to run the vehicle.
This is how older models worked.
So... The ignition key run position may not be providing 12v to the ignition circuit. Car Stalls untill restarted.
Use a 12v test light or multimeter to test primary side of spark circuit.
Newer models may not use these methods any more.

cheers

1999 chrysler cirrus 2.5l won't start


The ECM sends a GND signal to the Fuel Pump relay to switch it ON. When 'jumping' relays, there is a risk that you might feed +12V to Gnd switch line, in this case the ECM line. If left too long, this would blow the diodes in the ECM. Try using another ECM. Try following the ignition circuit from the ignition coil back to the ECM. One of the wires connected to coil should have +12v when IGN on. Sparking only happens when ECM sends GND pulses to the coil. If ECM is OK, check camshaft position sensor, which is also usually referred to by the ECM for ignition firing.

Where is the emergency shut off in a 1995 geo prizm?


All cars, EFI. (some have 3 fuse to operate ECU/spark/ fuel) check em yet?
check power to pump 12v cranking?
no, ? 12v, or 6v? (6v or near is corroded wires /conns)
check power (12v) from fuel pump relay cranking, got 12v there.
if yes , the the path is broken to the rear ) (inertial switch?, not in 95)
if not,12v now, the FP relay is bad or ECU is not turning it on.
if 12v is across the FP relay coil the ECU is working.
if 12v is across this relay, and output is dead, that is a bad relay
or the FI use feeding it is blown.
btw #1 all cars cut fuel (INJ) when spark is detected bad. (ecu)
btw#2 some (software) cut the fuel pump for same reasons.
btw#3, most cars, only activate the FP relay for 3 seconds key on, each time. and some cars only cranking, and running.
all these facts, need to be known to make progress, in EFI.
and more.

My 96 acura integra won't start but turn over


Get some engine starter spray. Follow instructions on spraying into intake. This will serve as a fuel source to test spark/ignition. You will want help cranking the car while you spray. If car stumbles and tries to run, you have a fuel problem. If after trying for a few minutes there is no change, then I would bet you don't have spark. Of course you could go further and say there could be a timing issue, no compression, etc. But I would start with the easy stuff first.
When was the last time you did a tune-up? Are the plugs in good shape?

If you remove the fuel line and crank the engine and get fuel then you could be assured that the crank sensor works but if there is no fuel while cranking then the crank sensor is most likely the fault. If the crank sensor is not the problem then it is most likely in the coil or distributor which the 97 is notorious for.

How do i test my fuel pump to find out if it is bad or not ?


spray quick start. If it starts then you know its fuel related. Then turn key on while someone listens to the pump thru the filler neck. It should run for about 2 seconds then shut off, If you hear it, and the car starts with quick start then the pump failed. If you do not hear it you will need to verify you have a 2 second 12v pulse on the green or grey wire at the connector. If you have the signal then the pump is bad. If no signal then you either popped a fuse, relay. or the PCM failed. Go to mitchell1diy for wiring diagrams and procedures. .

I have no power to the fuel pump unless I jump at the diagnosis under hood. I have 12 volts to the circuit opening relay and with the key turned forward I also have 12 volts to and the leg on the co relay....


fuel pump only runs for 3 seconds or when the engine is running. Cycle key with meter hooked up or ear on gastank.. Listen and watch. for a quick 3 seconds.. The spark your experiencing is most likely your touching a ground connection. If you have 3 seconds of power then you prabably need a fuel pump.

Car won't start


check backnnector on distributor assy. It's hard to find because is on the side just in the point nobody reach. Often it missconnect or broke. check, fix or re adjust as needed. check firing order of cables If not result.... 1.-unplug any spark cable and put a screwdriver inside it and place it in a safe place near a ground point. The object is try to see the spark jumping to ground. 1 or 2 cm will work for it. If you see spark, check fuel pump circuitry. uncap carburator and see if injectors spray gas when you try to engine. If you can see spark, change module inside the distributor cap.
if injector doesn't spray,check fuel pump, you must hear it for few seconds when you turn key to accs if you place your ear near thank. fuel pump work for few seconds but no spray on injectors: the same module above mentioned. if injector sprays and spark jump, the car must start

My 1990 F150 will not start sometimes. If I turn the switch to the on position and the fuel pump continues to run after 5 Sec , It will not start. If the pump stop running after 5 Sec , it will start.


when u turn the key to run but don't start the fuel pump shuts off after 5 seconds + or - 2 seconds, this is normal, the common cause of no start on your truck is the TFI ignition module on the distributor, subject of many recalls for failing, also change the stator inside the distributor, use factory parts, aftermarket parts fail very quickly. here is a picture of the parts.
da17e03.jpgThis is the stator

This is the TFI ignition module.

No Power to Fuel pump


I would check the ground for the fuel pump relay that operates the switch side of the relay.
You should have 2 12v inputs to the relay. When the relay gets 12v input, it closes the relay switch on the heavy current side that sends 12v to the fuel pump.

A relay is needed because you don't want heavy current going through the switch.

Also, most cars only run the fuel pump for 2 seconds when the key is turned on because you don't want the fuel pump running without the car running. If you listen closely at the fuel tank, you should hear the pump run for 2 seconds when you turn the key to "ON"
When the key is turned to "START", the fuel pump should run continuously.
The engine computer tells the fuel pump to shut off if the engine rpms are zero.
So, I would check the switch side of the relay. Power amd ground.
