Hello all!,..Allright Rich and I put the last pieces of the puzzle to get her running,..so!
[LIST][*]It turns over-DOES NOT FIRE!![*]doesnt seem to be a spark, if so its 1 cyl[*]all connections are connected except knock sensor and 02 sensor[*]not sure about the 2 connections under the plenum on the ignition (controller)-they are connected but they CAN be swapped,...

WHAT AM I MISSING??...All grounds are connected to the block.

is there a ignition fuse?
could it be the ignition control(under the plenum?...

let me know!!!!!!

Have you check the fuel and the pressure?

oricale · 03-14-2012

hello,..Lots of fuel,..injectors working good!.....no FIRE!

shaynezrl · 03-14-2012

It migh those connections under the plenum and above the bell housing. Make sure they are secure. It happen to me once ..the connections above the bell housing wasn't secure and it didn't start.

Hope you find it,

You probably bent a pin while plugging in the Ignition Module. Its not necessary to remove the plenum to look at the pins.Remove the plug look for a bent pin & carefully straighten it, then plug it back in.

Not uncommon, I've done it & so has just about everyone else.

The 4 connectors on the ignition module under the plenum are not interchangeable. The 2 towards the front carry the coil primary controls signal, the small one at the back of the module is switched B+. The big one carries ECM signals

Not to sure about the two connections on the controller that can be swapped,
but if they are for the coil drivers I would think you would have a backfire
of some sort. I would double check the crank sensor, this signals the coils to
fire. Also maybe one of the connections under the plenum was missed.

When ever I have something that doesn't start I go back to the basics;
Air-Fuel-Spark I usually have missed something hope this helps...jimmy

hey jerry,..I made an order,..I thought I got everything I needed,..But I guess I missed plenum gaskets?????

I will check the connections tomorrow!

Anything else it could be?

Heres what I will look at:

all four connections under the plenum
pins
cam sensor
confirm which plug goes to which spot (forward under the plenum) is which because they swapped

firing order(drivers 2-4-6-8 passenger:1-3-5-7 )..correct??

Make sure you didn't blow a fuse. A blown gauge fuse will cause a crank but no start because the ecm seas no tach RPM while cranking and will not fire the injectors. Been there done that.

Yep, you are right, Sammy. Retracted because I forgot.
Now I remember banging on the starter because I didn't step on the clutch pedal.
