Browning Posted May 8, 2011 Report Share Posted May 8, 2011 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 Quote Link to comment Share on other sites More sharing options...
Browning Posted May 22, 2011 Author Report Share Posted May 22, 2011 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? Quote Link to comment Share on other sites More sharing options...
SinisterSS Posted May 22, 2011 Report Share Posted May 22, 2011 what mods have been done? usually when the exhaust is glowing red its a sign of ignition timing and fuel mixtures have been changed Quote Link to comment Share on other sites More sharing options...

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?

Cordell Posted May 23, 2011 Report Share Posted May 23, 2011 no mods. Just a stock 3.4 Tried to have advance scan it but they said they wasn't getting any power? OBD1 scan tools need a power source, the DLC doesn't power the tool. Quote Link to comment Share on other sites More sharing options...

Browning Posted May 24, 2011 Author Report Share Posted May 24, 2011 bro's. Runs good on starting fluid. fuel pump? Quote Link to comment Share on other sites More sharing options...
Cordell Posted May 24, 2011 Report Share Posted May 24, 2011 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. Quote Link to comment Share on other sites More sharing options...

Browning Posted June 5, 2011 Author Report Share Posted June 5, 2011 wow that was weird. After he decided to just throw shit at it ie. fuel pump, plugs & wires, fuel regulator, etc. Turned out to be the ignition module on the column Quote Link to comment Share on other sites More sharing options...
