Truck died while I was driving. ECMB fuse kept on popping. After some troubleshooting found it was the pump.

Put in a new delphi, and fired her up. ROUGH idle & bogging when trying to accelerate.

Ok, Checked fuel pressure. 13psi.
Disconnected the brown/Tan wire, set the timing to 0. Rough idle.
Checked TPS. OK.
Noticed after idling for a while SES lights
Checked codes. -33. Map checks out.
blocked off EGR. Same.
Noticed an injector not spraying right. Replaced. Same.
checked timing. Disconnecting the bypass causes her to stall. UGH!
Changed coil, wires, distributor was replaced over the summer, but replaced cap & rotor. Same.
Compression test 145-165 155 avg

Pulled ignition module and had it tested 3 times. Passed.

Broke out WinALDL that reads the computer . Everything looks good but running super rich, and map readings aren't where they should be.

Pulled plugs. Covered in SUIT! HMM... Replaced plugs.

Map is now running fine, probably all the suit.

So while watching the computer , I started advancing the timing. She's running much better, and disconnecting the bypass lets her idle for a little while before she stall. Still bogs and stalls while accelerating but better.

Plug isn't covered in suit.

Brought her to TDC, and pulled the cap. rotor is still pointing to the post on the ignition coil, but now the distributor is so advanced It's almost pointing to the #8 plug.

What am I missing?
