Check engine on but when we try to run the self diagnostics by jumping the pins on the connector under the dash it doesn't display any codes. also, it kicks a relay under the hood and you can hear a clicking on the pass. side of the engine. Advance couldn't run a test either

Any one have any ideas? Found online about the #13 fuse having something to do about it but it's fine.

 

Car is running weird and need to figure it out. Some times it starts, some times it doesn't and turns over hard. Also, a few nights ago the passenger side manifold was glowing. Coils tested fine, and just put new plugs and wires in it.

 

Yesterday he got it fired up and it ran real choppy, almost as if it was running on all cylinders. Fired it back up 20 minutes later and it ran fine?

This doesn't really make sense.

 

Anyway, sounds kind of like a sticking or clogged fuel injector. 93 is a bastard year don't really know about the self diag, have you tried an OBD1 scan tool? Does the CEL flash? or is it on?

what mods have been done? usually when the exhaust is glowing red its a sign of ignition timing and fuel mixtures have been changed

no mods. Just a stock 3.4

Tried to have advance scan it but they said they wasn't getting any power?

bro's. Runs good on starting fluid. fuel pump?

 

Maybe, or clogged fuel filter, bad injector, still needs narrowed down. Start with fuel pressure, then see if its a single cylinder causing the roughness by unplugging the spark plug wires one at a time.
