Almost.... there
Hi, Newbie here... 1996 Cobra SVT Build # 253
For 5 months now I have been restoring / building a '96 cobra 'vert
( SVT build # 253 ). Everything is new, rebuilt, detailed, clean... ect,ect I have completely gone thru this from bumper to bumper..... Looks good...runs terrible...
This car never ran whenI bought it as a severely overheated mechanics special....
I AM IN... DEEP. I am not sure how deep anymore
So,yesterday.. .all excited... it's ready.... I crank it over / start up.SHAKES BAD it has a dead hole #6 / won't rev...feels like limp mode. Timing is locked in at 15 degrees (no advance curve) and o2 sensors are flat (no activity) Is this limp mode????? I started checking basics, rechecking basics
This was a totally dead / non-op /severely overheated basket case before I ever saw the car, it has never run in my presence...see what I am dealing with
The good news...It starts right up, has 65 psi oil press, no engine noise. YES,...
Checked all the basics--- Did a comp test of #6 = 175 psi good, no signal pulse @ #6 injector (used a noid light)
Weird,It has 20 inches vac "steady" @ idle And 40 psi fuel press.
Also I disconnected several things while running, I get no CEL. It does perform the standard a self test on ign start. The CEL goes out right after start up
The engine currently has 90 seconds on it... need to figure this issue out
Has no codes, runs terrible... shakes, acts really lean (it is) How to fix injector signal for Cyl #6 ??? I ohm'd the harness that's not it.
PCM?
I can't give up yet...I am so close.... HELP This car turned out (restored) sweet, yet...it runs very bad... any help would be appreciated... THANKS

A simple FIX !!! ;0)
Update! Good news!!!!!! I had spark plug wires for #5 & 6 swapped at coil. Misfire gone. YES! Runs so smooth.... Ice cold AC too. ;0)
Lastly... Needs a fuel pump ( low volume flow) gas is old / bad...
I'll post pics when I get it on the street.

Nice catch! Don't you love that feeling of relief when you realize it's something small and easy to correct when it feels like something huge is looming over you!
Can't wait to see pics and hear more of the story.
