My 1994 chevy 1500 has been having a hard time starting out it idles ok and revs up but when I let the clutch out and start out it jumps and jerks really bad. Dose ok in higher gears and faster speeds. Then I go a 44 code for it running lean so I replaced the o2 sensor and it is still acting up. I all so replaced the plugs, distributor cap, rotor, and a new fuel fillter and I found two wires on the coil that had insulation off of them and where touching I really thought that would fix it but still not working very well.

Check to see how much fuel pressure you have if it's TBI then you should have 9-11 p.S.I. If it's cpi or port fuel you shoul dhave alot more

I checked the fuel pressure today and it is around 5psi so I am thinking I need to change the fuel pump I hope it is and it fixes it.
