this is dave and I'm here to help. It sounds like you have a lot apart already is that right?
usually a bad crank sensor will make the coils fire once then not fire again but that will also kill injector pulse. does the injectors pulse the whole time you are cranking?
if your getting a lot of smoke and you do have pulse I think your right on the money with a timing problem. if the cam and crank signals are not in time with each other it will do the same thing and the smoke is usually all the unburned fuel coming out. If you can do a compression check on all the cylinders we can be more sure of a timing problem
ok well the mass air flow will not effect spark so that could have just been coincidental. if it still wont start now you really need to do a compression test to see whats going on inside the motor
let me no what you get for numbers
that's a good sign that they are all pretty even. do you have access to a scan tool so you can see live data as you crank it
yea that's good. does the security light stay on or flash while you crank or does it go off shortly after you start cranking. This is very important
ok so that can rule out a security problem. have you checked actual fuel pressure at the rail yet and try to take a sample of the fuel to rule out contamination
it could very well be. They can be expensive so i was trying to help rule everything else that is common out first. You really need to do all six coils and should get OE coils because aftermarkets can be very problematic for these cars
not really but they do have major problem with the coils in general and there may be 1 or two that are good. But if enough of them are bad the car wont start. It seems like you have everything else that you need for the car to run so if you have good ones try that first. There is also an issue where the wiring harness runs near the strut tower the wires can rub and cause a short i would look closely at the wires as well
should be on pass side if my mind serves me right
ok sounds good
