93' Lt1 Ta - No Start - No Fire! Help!!!

[Zan Stout]

I have a 93' LT1 TA with a pass key 2 bypass module on it that has been working fine for a long while. A week ago my security light and check engine soon light came on and won't go off, NO CODES. The starter turns over and the fuel pump pressures up to the injectors, but there is no fire or spark to the plugs. Have checked and ran all the tests on ignition parts like distributor, coil, module and continuity and voltage tests on the wires in between everything checks out good. All fuses good. Can not find any thing wrong. This is my only ride, I am hitching back and forth to work. I need help badly. Owner's Manual states as long as the security light stays on it will not start. HELP ME PLEASE!!!! I am losing patients fast. Thanks in advance for any help you can provide.

Have you tried swapping in a new coil or opening up the opti to see if the rotor got damaged?

[Zan Stout]

No I don't think we have tried a different coil, will have to check and I don't know what opti is, could you explain that on? Will get back with the answer about the coil, asap.

Thanks!

The opti is your distributor which is mounted right under/behind your water pump.

My husband says, "yes", he did try another coil, but not the distributor it is fairly new and all the test checked out showing that it isn't having any problems. Plus, they are very expensive just to check to see if it is it and you can' t return any electrical parts.

Thanks

If you have spark at the coil but not at the spark plugs then the only items I would suspect would be the distributor cap and rotor and/or the plug wires.

Ok, I will tell my husband. Thanks!
