Hi, My Name is ***** ***** for posting your question to just answer. I am a independent contractor for just answer, and ASE Certified Master Auto Technician with 20 years experience. I am confident we can resolve your problem together.Please remember I don't know your skill level. I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies to get to a satisfactory resolution.There will probably be some equipment needed for a proper diagnosis. If you are not comfortable with this or do not have any test equipment please let me know ASAP. I also try to give all of the information you may need expecting a positive rating. I am not compensated for my time until you leave a positive rating.
What kind of test equipment do you have?
Injector Noid Light?
can you get an injector noid light? They are available at most parts stores and inexpensive. It should flash when cranking. You unplug an injector and place on connector
Do you have a scanner that has DATA? Can you tell me coolant temp and RPM while cranking?
I need some data. I can opt out and see if anyone else can help.
when you say it wont start,,will it not fire at all?
just to clarify,it does have a sprk on the plug wires,,right?
how and when did this problem first begin?
does the security light stay on with the key on?
tell me all you can
ok,,will it start with a prime?starting fluid or a little fuel into the throttle body?
how much fuel pressure does it have?
so it wont start even with a prime?
if not,test for a spark again,,it should fire with a prime if it has a sprk regardless.,,if it doesnt,im going to think it has jumped time[not likely with this engine]
again,confirm a spark on the plug wires
