average should be about 300-500 bucks. (including the part)

slave cylinder is my first suspect.

everything you need below. NOTE: Rocker arms arent under torque. You can google the process to adjust them, but just enough to take the slap out.... too tight and the valves will go stupid. file:///C:/Users/owner/Desktop/Small%20Block%20Chevrolet%20V8%20Engine%20Specs%20%20%20Torque%20Specs%20-%20Cylinder%20Numbering%20-%20Firing%20Order%20-%20Distributor%20Rotation%20-%20SB%20Chevy%20267%20305%20327%20350%20400%20Cid.htm

year of truck?Does gauge jump around or just drop fast after 1/2 tank?

um..... start it up again....or did you have a question?I'm not trying to be rude, or funny, but you just made a statement and didn't ask a question, nor did you say what may have gone on when trying to start it again.

check for air, fuel and spark.

put the rotor on the dist and gently turn it while very slowly lowering the dist back in. You need to make EXTRA sure you don't drop that pump shaft into the block. I trust you have the engine cylinder #1 at TDC and are ready to slap it back together, but if you have more questions on that, let me know.

mine was both a bad wiper switch and wiper motor. when my dash lights acted up, a new HL switch sorted me out fine.

Check coolant temperature sensor....usually on right side of block. Hard to get to,but pull wire and remove,install new..they are les than $20 here..good luck

If you have a way, check the fuel pressure at the fuel pressure regulator. Sounds like there is no fuel pressure. The injectors are controlled by the computer. Check fuse block for bad injector fuses.

check fuel filter, pressure and maybe a plugged cat.

Check the TPS, (throttle position sensor), and the fuel pressure. If it is a TBI model the fuel pressure should be 6-12psi. If it is a MPI injection system the pressure should be about 55-65psi.

the pump can be weak or obstructed, could be fuel filter too.

you have to understand injectors pulse come like thispcm have to know if engine rpm running over 400rpmkey is on injectors have a + positive and a ground that is given by pcm

insulation failure. is it arcing from the lead - then replace lead, is it arcing across the coil face - replace coil. Generic coils are available

insulation breakdown. is the ht lead insulation ok? otherwise coil insulation meaning replace coil

Check for a blown fuse or loose or broken wire.
