1990 Winnebago with 454 tbi starts and runs to 30 seconds

Customer Question

1990 Winnebago with 454 tbi starts and runs for 10 to 30 seconds then a large shot of fuel in the left throttle causes it to flood and die. Check engine light is erratic. Have installed new coil, electronic module in the distributor, dist cap and rotor, fuel filter. Problem still there.

Hi, I’m Ron and I’ll be helping you today.
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

I remember years ago that a defective alternator caused that to happen. Have the charging system check for full fielding operation first, then we can address a possible computer problem.

Thanks, Ron
