2.3L ('83-'97) Crank, No Start.

Still don’t have spark after checking all fuses and grounds, replacing dis module, battery, coil packs, crankshaft positioning sensor and spark plugs….

Not sure what else to do with it. Any ideas?

 

[franklin2]

Is this the one that you can't read the codes on? Or was that someone else? The codes may give you a clue where to look.

 

[RustRatz]

Yeah, it’s an obd1 truck. Can’t read the codes

You either have a power or ground issue or something isn't working (I know, kinda obvious...)

For codes, have you looked HERE? It could tell you something but the codes on the early stuff is kinda lacking...

Not having spark points to something with the crank sensor or DIS module, there's a wiring diagram for a '91 which is close enough in the turbo swap area of the tech library, don't remember if the DIS module is in there or not and I don't have the DIS module wiring memorized anymore... my '90 has been running on one coil pack with the tach working for a long time now...

 

[RustRatz]

I’ll have to take a look at the diagram. I believe it’s a ground issue, but I didn’t have a good detailed diagram of the harness.

 

[RustRatz]

Scott, I never did find that diagram. I’m not sure exactly where it is

FOUND IT, the DIS module connectors are in the center, for funzies I have this too apparently (completely forgot about this, found when looking for something else...):
