93 Atx No Spark!!!

[yamasho93]

OK, so I have a 93 SHO atx that has no spark, tranny went out on me so I replaced that. reconnected everything together and now it has no spark. you hear the fuel pump turn on, has pressure, tachometer moves when you turn car over goes up to about 600 RPMS, and according to some of the other threads if it dont budge bad crank sensor so I dont think that would be it. checked all other connections and still nothing have tried three different DIS boxes and all with the same result tried junkyard coil pack still nada even the one that was on the car when the transmission went out doesnt work please HELP!!! been without my SHO for 4 months trying to get $ching$ for tranny. ALL I WANT TO DO IS HEAR THE SECONDARIES


OKay the fuse is good, the ground strap is connected to the strut tower bolts, the intake crossover tube one of the bolts is broke. the coil the DIS and the cam sensor all have power to them as well as the cPS.

First thing, check the IGN fuse. If blown, disconnect the coolant reservoir sensor before replacing.

There's a logical process that needs to be followed, quit swapping parts.

Like mentioned, there is a logical process to follow. Check all the fuses and make sure they are all good. Follow that by running the codes and see if that leads you in a direction. If not, make sure you have the ground strap from the intake to the body and its good. Check the two bolts that hold the crossover tube on the intake to the engine. Make sure they are secure. Make sure you get a test light. That will eliminate the need for swapping parts.

ok, I know the ignition fuse is good. I have tried running the codes but I am sure that I am doing something wrong. Now for the ground strap I have that connected to the bolts that hold the strut in the strut tower. is that okay? just a question why do the bolts for the crossover tube matter is that part of the grounding system. I have a test light and the cam sensor has power to it as well as the DIS and the coil pack.

Your ground path for the DIS module runs:

Bottom two module mounting screws > cross-over tube > brackets > heads > jumper to firewall by #1 cylinder. Another ground wire wire goes from the negative terminal of the battery via a connector to the passenger side strut tower.

ALL must be intact otherwise you won't get a proper ignition system.

You said you tried running codes, but you failed to report what happened. Do so.

Does your CEL come on when the ignition first comes on or does it not?
