Hello, did you check for spark to the spark plugs?
There are certains steps that need to be checked starting with spark confirmation,the next step depends on whether there is fire to the spark plugs or not.
I see you have gone offline so it's not possible to continue in the chat mode.
My timing light indicates that there is no spark coming to the plug
the plugs are new
thanks for the reply, check to for battery voltage to the plus side of the coil or at the B+ terminal of the diagnostic connector under the hood.
with a testlight or voltmeter check both sides of the EFI fuse.
with the key on for both tests
12 vdc and the efi fuse is good
i loaned my car out and buddy said it went dead after he boosted someone
Does the engine turn over but not fire up?
When turning the key on do the dash lights turn on as well as the check engine light?
yes , no spark to the plugs
Ok, so you have battery voltage to the B+ terminal at the check connector is this so?
Did you check the other fuses on the inside at the fuse panel at the left loer dash?
all fuses are ok
Check the airflow meter connector.
it is connected
With the key on put a jumper wire in the diagnostic connector between the terminals TE1 and E1 and observe the check engine light, it will start flashing, I'm looking for a trouble code, if there is one the light will flash a two digit code, for example a code 12 would be one blink followed by two, let me know if there is a trouble code. So far with what you have told me there should be spark.
one flash pause , 4 flashes
Ok, let me see what that is be right back.
That is a code 14 meaning the ECM did not get a confirmation signal that there is spark, did you replace the coil and igniter module both?
Did you replace the engine control module (computer)?
There is a chance that when your friend jumped the battery to another car that the battery may have been connected backwards for an instant, this could have damaged the computer . with everything that has been checked and the parts that were replaced i really don't have any other place to go with this.
I assumed the ecu was damaged , I thank you for your help
