cammaro z28 1994 v8 5.7 L Not Sparking problem please read my problem i have a chevy cammaro z28 1994 v8 5.7 L
Not Sparking problem
this is the entire history of this prob/solus EXPLANATION (my point of view)
its getting fuel i had an injector un pluged from engine to make shure, the engine turns over but wont start for 1.no spark 2 i have changed the folowing parts:
Spark Plugs, Spark Plug Wires, ICM Modual, ICM Coil, PCM (Computer), Starter, Fuses in side car and under hood, Fuel Pump,
a feand turns the key while i look at the meater conected to ground and the the wire i am checking
i have checked power in the wires every time the key is turned to start the car.....
i check power in coil wire ( pink ) that goes to the fuse that has 10 watts in the fuse box under the hood 12 volts... and i check power in the red wires from the coil to the ICM ignition Module 0 volts ... and i check the power in the WHITE wire that goes from the Module to the PCM (COMPUTER) 0.250 Volts ITS SUPOSED TO HAVE 12 OR SO VOLTS RIGHT? So i changed the PCM and transfered the KNOCK MODULE to the new PCM. THE WHITE WITE still has only 0.250 volts when the key is turned. so i found pictures of the PCM CONNECTOR "A" (RED) "B" (BLACK) "C" (GRAY/CLEAR) "D" (BLUE) these are the Documents: http://tinypic.com/view.php?pic=igj0o3&s=8#.VBpY80Ca9hI

I HAVE USE THESE SHEETS TO FOLLOW WIRES TO THERE SORCES.
i started with the PCM CONNECTOR "B" (BLACK) and PCM CONNECTOR "D" (BLUE) THE BOXED IN PCM IGNITION FEED 439 PNK (PINK WIRE) ON BOTH SHEETS AT THE BOTTOM AND THE OTHER AT THE TOP... THEY LEAD FROM THE PCM TO THE MASS AIR METAL BOX SENSOR IN FONT OF THE ENGINE... I HAVENT CHECKED THIS WIRE FOR VOLTAGE READING (could this be the problem?) DOES IT SEND POWER TO THE pcm IF AIR PASSES THROUGHT IT? IN RETURN SEND POWER TO THE WHITE WIRE GOING TO THE IGNITION CONTROLE?
AFTER i checked the PCM BATTERY FEED 340 ORN (ORANGE WIRE) shown on the PCM CONNECTOR "B" (BLACK) in the middle and the bottom of the page... and they run togeter into the car from the computer through the car firewall on pasenger side and under the dash kick panels of the passanger and driver side to the fuse box on the side of the dash going to the left bottom corner side of the fuse box it has 12. volts going to the computer... SO THE WHITE WIRE SHOULD BE GETTING POWER TO SPARK THE SPARK PLUGS.
I HAVE A TEORY THAT I BELIEVE MAY WORK TO GET THE SPARK PLUGS TO SPARK: HERE IT IS: ON THE PCM CONNECTOR "A" (RED) SHEET BOXED IN RED AT THE BOTTOM TRACTION CONTROLE SYSTEM SPARK RETARD REQUEST... IF I SNIPPED / CUT THE WIRE WILL THIS MAKE THE SPARK PLUGS SPARK OR WILL THIS IN EFFECT CAUSE VITAL, MAJOR, ENGINE PROBLEMS?
also WHAT IS A POSIBLE SOLUTION TO THE SPARK ISSUE. ITS THE ONLY PROBLEM I HAVE THAT I CANT START THE CAR....
PLEASE HELP
