Question about Cars & Trucks
MY MAN TRUCK IS HAVING THIS PROBLEM AS SOON AS I START THE ENGINE IT GIVES ERROR 3780-01 AND ENGINE LIGHT IS DISPLAYED. ENGINE LOOSES POWER. PLEASE HELP
Its probably trying to tell you there's something wrong with the engine? Some ECU controlled engines go to a soft power mode to limp along with. Search for a manual or contact a dealer. I presume you have done all the engine checks?

Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.

you might try unhooking the battiey for 20min both + and - posties cuz that will force the computor to have to resest only if you have addressied the fuel pressure problem which taht would most likly be your filter which isn't all that much
