1992 360 tbi no spark, or fuel

[jmos4]

Hi,

Well long shot but here's my dilemma

Got a 1992 w250 that has a 360 tbi/nv4500 and won't start.

Replaced all the sensors in the distributor
Replaced all the relays on the fender
Replaced the fuel pump

No power to the fuel pump, so I bypassed the harness and still no spark. Also no power to the coil either.

At this point I am just replacing parts with no end in site only thing left is the ECM and that's unavailable and not sure that is even the issue.

Any ideas, besides the obvious add a carb and points, or drop in a diesel (long term plan but not in present time frame)

Regards,

Is the ASD relay intact and working?

Hi,

No idea, I replaced the relay, I am not very good at troubleshooting electrical issues like this no obvious melted or worn through wires.

Best I could say is, download the factory service manual. You can find it with Google. That will help you the most finding the problem.

Check the fusible links on top of the drivers wheel well. Try to stretch them one at a time. If any of them stretch like a rubber band they are it is bad. It means the wire inside is broken. Replace with the correct color and diameter link ! DO NOT USE FUSES INSTEAD ! SOLDER ALL JOINTS ! Also check big wire that comes off the + battery cable that plugs into the main harness. Not the red and brown wires that go to the starter !
