I'll admit - i took my sweet time with the few mods i've been working on but today was to day it was all going back together finally. I was supose to have pics and a sound clip too.
New BBK shortie headers, MSD 8.5 mm plug wires, Iridum plugs, MSD cap and rotor kit, MSD ignition coil, LT4 knock modual, air foil for the throttle body, and a hi-output alternator.
Now the car cranks but wont for the life of me fire up. I could sit there cranking till the battery dies if i wanted to and she wont fire. The engine is getting fuel becasue the pressue is there and i can smell it. So it's gota be ignition. I have a gut feelign that the opti is failing. Either the cap and rotor is defective or the whole unit needed replaced - not just the cap & rotor. Problem is - since i did it all at once, there's no telling what part of the engine is probleming. So i'm going have her towed this thursday to a repair shop to diagnose the thing and tell me what i did that ****** it up. Hopfully it's simple. But i have a feeling its the opti.

This has not been a good day. If it is the opti there goes the money i had saved for the side exiting exaust plan.

weak, Ill hope for you that its nothing major.

check spark and you'll have your answer.

MeenZ28

OK - how do you check spark?

Mikerock

Pull the number one plug wire, which is front driver side. and you can stick a 3/8's ratchet extension into the end of it or something metal, and lay it on your valve cover have someone crank the engine, in park or neutral. if there are sparks, well then you have spark.

also if you didn't put the rotor back in the right spot you are going to have to find Top dead center and place the rotor in the right place.

that sucks dude hope its nothing big

im really sorry to hear that grant. i hope it all works out for ya

on the opti it only goes on one way.

but grant how do you know there's fuel pressure? did you check it with a gauge? dont assume there is just cuz you smell it.

Its probably ignition tho, and my guess, something very simple. like the coil, module, or opti arent plugged in.

I had two of the MSD coils fail on me. I wouldn't rule that out quite yet either...

When you took off the cap and rotor did you spin the opti itself to see how easy it spun? Usually when they are getting bad they get kinda sketchy, but if it spun smoothly then I would doubt its the opti. I know there have been other symtoms but everyone that I have done has been this way.

Another way to check spark thats a little easier and less likely to get you shocked would be just take a plug you know works and put it in any wire and then ground that plug to the block or header. If you hold the plug end you won't get shocked, assuming your wires are good that is.

Are you getting the SES light when the car is trying to start?

well nothing for me to say, except good luck. hope you figure it out.

aarontracy

if u dont get spark off the opti it could still be the coil. u can check the coil the same way as u do the opti with the spark plug in the end and ground it. also go ahead and double check all ur plugs and ur firing order.

your engine timing is off. are you sure you put the plugs on in the right order? and is your distributer set to what it was before you took it apart? i usually mark with a marker before i take them apart to make sure.

blue89vert

wouldn't it at least run when the timing is messed up...when i changed my headers and messed up all the plug wires orders it still ran...just kept backfiring... so i fixed it no big
