NO SPARK.,.. NEED A VIPER TECH!!!!!!

[Mark Red GTS Cooper]

All,

Have a problem,, I was driving my Viper, running fine, Stoped and started several times for shopping and gas.

Then 3 blocks from my house, the car shuts off like a light switch.

The motor turns over, I can hear the fuel fump fill and stop, then start when I crank, but when I pulled a plug, no spark.

I have a MSD boost retard box and I bypassed it, I have a Dytech fuel mgmt computer and I bypassed it, so I am stock other than the super charger.

Suggestions,,,,could it be a crank sensor???

HELP

Thanks,
Mark

It SOUNDS strange, but you know what? I had the exact same thing happen to my MSD6BT in my blown camaro. JUST like that. Bypassed the box, cranked right up. Reconnected the box a few days later, runs fine.

I think they need a reset button. :-D

I by passed the MSD, and no such luck. I cycled power from the jump start block, no luck.....

Did you try and find any trouble codes? Turn key on/off 3 times in 5 seconds then leave on the last time. Trouble codes will flash and can tell you things like "No Cam Signal" or "No Crank Signal" It's much better to get an OBD II to read the codes, I'm sure you have some codes based on your problem. Do you have a service manual? According to it "The PCM supplies battery voltage to the ignition coil through the automatic shutdown relay" This relay is located under the hood (fuse box) next to the pos batt contact, you should be able to swap the relay with the A/C relay as I think they are the same. Hope that helps

MES,

Already tried the ASD relay.. No luck..

So hopefully I can get the dealer to pick it up..
