On the old farm truck "1988 chevy 1500 4x4 305 TBI 5spd" lost all power. Idle is sort of rough. I almost doesn't have enough power to pull out. You have to hold it on the floor to pull out. Will not hardly go up hill. First I thought cat might be stopped up. So I cut it off. No help. Thought maybe fuel or air filter. Both needed changed so I changed them. No help. It doesn't act like it is flooding out "no black smoke". The check engine light has not come on. So I don't think it will have any codes stored but I'll see if local auto parts has a scanner I can use. I don't think it the clutch slipping RPMs aren't raising. It just like it isn't taking fuel or getting it. As for starting it starts fine I don't even have to pump it or anything.So I'm thinking now maybe fuel pump. Any suggestions. I really hate to drop the tank if that is not it. Thanks.

dont drop the tank, pull the bed, easier, espically if you have a full tank. But first, pull cap off dist, check for corrosion, replace plugs and wires, take off coil and have it tested at autozone. then report findings.

Replaced fuel pump. It was fun. Raining, almost full tank of gas, and by myself. Did not fix it. What to check now?

Might have figured it out. The plugs that plug into the injector are brittle, cracked, just gone. Where can I get those?

EGR. look into it. and also, go buy a haynes manual and learn how to extract the codes yourself. i learned how to do it when i was 16 with a paperclip
