How do I find a power door wiring schematic for a 98 pontiac Transport

SOURCE: We are replacing the fuel filter in a 98 pontiac

Assuming you mean replacing the fuel PUMP, the 2 wires are different guages. Connect the lighter wire to the lighter wire and the heavier wire to the heavier wire. If the new harness uses both the same size wires, the heavier wire on the vehicle side (solid black) is for the fuel pump ground. Lighter wire is for fuel guage sending unit.

i would try your local dealers parts department ....you may have to persuade him a little as if you will return to buy parts but they have all the diagrams youll need good luck

SOURCE: no fire on 98 transport

recheck all eletrical connections on the engine also recheck for pinched wires and coputer ground wires.

Well you hit all the major ones, could be crank position sensor, ignition module, a bad coil pack (it should have 3), you need to check that you have spark to each plug while the engine is turning over (!!!be careful as this will hurt if you get shocked!!!), this will rule out coil packs. if you have no spark to any plug your looking at a bad ingnition module (which is what the coil packs bolt to). Hope this gets you on the right track!
