please help truck broke down....engine flooding out and missing cant figure it out

[withoutfear33]

in my 89 i finally got it running good. had tons of power and ran strong.. parked it to work on geting the bed aligned correctly and after that i get in to start it up and it starts running rough and surging and flooding its self out...

i pulled the plugs and they were solid black so i figured now was a good time to do a full tune up..

i have replaced the plugs, wires, cap and rotor, and the fuel filter along with the oil... i was excited thinking this would solve my problem and it didnt fix a thing..

looking at the injectors it appears they are spraying normal and of course when is surges and revs its self up they spray harder.. also now it will flood out and die and wont start for a lil bit..


i just dont understand it, it was running to good...


any idea im stuck at a buddys house currently.

Ignition module maybe?

im not sure i checked timing and its all good. im at a loss i was thinking the TPS or CTS but i hate wasting money on unneeded crap.. may go buy it real quick and see what i can do.. maybe fuel press reg... just a ton of stuff it could be i just dont have the knowledge to narrow it down without buying and replaing everything

could the gasket between the throttlebody and intake be bad? sounds like excessive suction, but thn again i have the intake cover off and its idling weird

I would want to put a live data scanner on it before I could really say.

im getting a 33 code.. which i know means its running rich i just dont know why

the little module in the distributor i had that problem in my 94 its would run good then spit and spudder blow black smoke and then die i dont remember what the part was called though

took electrical contact spray and cleaned all the connectors.. so it fixed it for 20min or running then i removed the battery to clear codes then it wouldnt start haha.. so i waited and it finally started and ran fine again.. i think i have a sensor going bad i just still gotta figure out which one

kinda sounds like fuel pump to me

if it does ot again try unplugging the cts, a lot of times they will idle ok if unplugged if you don't have acess to a scanner
