no spark at plugs?

Good morning,

With the key on, you should have power to the positive side of the coil. You should also have power to the negative side as well. If you do not, replace the coil.

This guide can help us

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

i changed the motor on my 01 .... it is a 5.4 L ... my theft is flashing . and i am not getting power to my fuel pump or any spark is there a way to reset the theft or to bypass it ?

You will have to re-learn the key for the PATS to reconize the key.

you guys responed to my ? what info do you need to re learn the key thank u very much

Look in the owners manual. It probably is located in there as well.

i have no spark at the 2 modules under the hood i have replaced one of the spark plug modules already and i still can't seem to get spark. i have tested the fuel system the pump is priming and the fuel rails have fuel in it. was wondering what the next step is or where to go

Are you refering to the coils? Are you getting power to them? Has the check engine light come on? Crank sensor?

Let me know.
Joe

yes i replaced one of the coils still no spark i have no check engine light on the truck worked fine yesterday and this morning would not fire up

also how would i check to see if there is power there

If you have a basic volt meter, just put one side to ground and the other to the wiring going to the coil.

the truck cranks but wont start. theres no spark to the coils and no fuel. changed the cranksensor and i checked all the fuses and battery and i even checked the computer it looks fine. please help

should also mention the check engine light wont come one with key is turned over.

Under the hood is in the relay box is an EEC relay. If bad, it will shut down fuel and spark. Switch it with a known good one with the same part number and see if things change.

i have 97 f150 4x4 5 speed getting no fuel or spark changed crank sensor checked fuses what should i check next parked truck two hours later would not start it will crank but not start

spray some starting fluid into the air filter and see if it tries to start.

you need to check the fuel pressure, remove one of the coils and put a plug on the end and see if it sparks.

no fuel at fuel rails and already checked for spark the way you instructed

you need to check for power to the pump. the inertia switch is in the right front kick panel. current will last 2 seconds when the key is on. verify that power.

check the fuses with a test light to verify all powers to the pcm.

We just bought a 97 Ford F150 a few months ago and since it has gotten colder and a bit damper, the truck has started on some days and not on others. most recently it won't start at all. We've checked the relays and replaced them, and put a new coil in, but still no start. any suggestions on what needs to be done?

well your saying no spark is getting to the distributor? or you saying no spark is coming from the coil.

does it fire up with starting fluid sprayed in the throttle body.

The truck ran when I parked it. i sprayed brake cleaner on driver side valve cover because it was rusty and was going to patch up. After the brake cleaner rinsed off with water hose did not spray at full force just rinse off to clean up. waited for a few days to make sure everything was dry. Did what I had to do the next day did not start. I replaced coil, control module, cap rotor. Sprayed electric cleaner on connectors dryer out with air hose and still nothing. any suggestions?

It sounds like you got the PCM relay wet.
Here is a guide and a diagram of where the relay is. Also, I would check the connector for the ignition module connector for moisture.

I blew out ignition module connector also replaced module it was tested and was bad. did you mean EEC or ECC not exactly sure everything I looked for was EEC.

Sorry, PCM relay.

Dryed out. Nothing yet could the relay be bad

O ya it could be bad here is a test you can use to check and bypass it just to see if the engine starts.

Also remove the connectors from the ECM and see if there is moisture in there as well.

Please let us know what happens.
