Hello everyone.

Got a 94' P30 chassis RV w/ tbi 454. Started it up today and let it warm up for 3-4 minutes and all seemed well. I then drove the rig a few hundred yards across the storage lot yard, noticed the idle was rough and the check engine light were on. I then killed the motor and proceeded to wash the vehicle (which was my original intention for driving it across the lot).

After washing it I fired the motor and it sputtered for a few seconds like it was gonna turn over and run, but no dice. Now it just cranks with no signs of life

I pulled the air cleaner cover and it appears its getting a good spray of fuel from both injectors. I can see the fuel spray and smell it.

I also pulled the right rear plug and was able to see spark when I grounded it to the block and cranked it.

It appears to have fuel and spark and I'm at a loss here. I've searched the web and it appears the ignition control modules are suspect for an issue like this, but I hate to start throwing parts (and cash) at an unknown problem.

Any ideas where to begin my testing?
Thanks.
