Have an 89 chevy 1500 with 350 engine ran fine yesterday is getting spark is getting gas {maybe too much gas} will run then stall if floored but black smoke not blown engine what else could it be?

Replace the Ignition Control Module (ICM)--that will likely solve the problem. Easy fix.

Went and had icm checked it is good so it still don't start acts like too much gas

Anyone have any ideas what else could be was running fine then just quit will fire but have to hold to floor to get it to do that but when fires runs like crap then quits
Acts like getting too much gas or not enough air with fuel anyone have any ideas

I wish I had a dollar for every ICM that tested fine on a Well's machine that didn't work. IMO, testing ICMs and coils is virtually a waste of time. Instead, I recommend replacing them every 120,000 miles or 10 years, whichever comes first.

The fuel is likely fine--it's the compromised ignition system (ICM), which is the problem. It's just too much fuel for a weak ignition system.

Tx greasemonkey well I did have it checked out it was OK I then did some research and found out that the temp sensor would also make it dump fuel into motor changed that and truck is now running smooth also the temp sensor is what makes the truck put more fuel to engine on really cold days anyway thanks for the try just thought id let you know what was outcome
