Picked up a non-running '94 LWB RRC a few weeks ago. Once I got it here I discovered it did not have spark at the coil. Decided to replace the amplifier and in doing so I discovered a bad spade on the ground wire to the dizzy. I ran a new ground and went ahead and replaced the amplifier since the dizzy was already out. Truck would start sometimes, other times not. Looked at the code and continued to throw 23 so I replaced the fuel pump. The code went away and the truck was running fine. Only issue is it would take a 10-15 seconds, sometimes longer, to start when cold. Once it was running if you turned it off and restarted it within 30 mins or so it would restart immediately.
Drove it around town a bit and it started stalling at red lights. It would restart without issue but couldn't find idle. Tried to clean the stepper motor and it didn't help. Replaced the stepper motor and it idles. Drive it around a bit more and drives as it should. Drove 20miles west on 66 then back on side roads and the truck ran great. Code free, no CEL, and running great other than the slow start when cold.
Son has a tournament and wants to take the new truck. The trip is about 250miles away. Decide this would be a nice long test drive so we went for it. About 70 miles into the trip the CEL goes on but the truck it running fine. We drive about 125miles and my son wants to get something to drink so we take the next exit and truck is wanting to stall as we come to the light. We hit the gas station and top off (we were just under a 1/2 tank) and poke around the engine compartment everything looks good. CEL is showing code 44 (left 02). Start it back up and the truck running fine.
Since its running fine full I decide to keep it above 1/2 tank and continue on our journey. The rest of the drive there was fine and no issues running around to games once we are there. Tournament is over so head home. We're approaching 1/2 tank and the truck is feeling sluggish so I take the next exit to fill up. It wants to stall as we come to a stop but i'm able to get to the pump. Gas up but this time when it starts it doesn't sound great. I have to keep my foot on the gas to keep idle and when we pull away it has no power. We pull over and catch a ride home with a teammate.
I grab a bunch of spares and head up this morning. Went to change the 02 sensor and noticed it was very loose, though maybe that was causing the fault. Pulled a plug and they were pretty white. Tried starting but the engine wouldn't start. Replaced all plugs and still no start.
Any ideas?
Would the coolant temp sensor or fuel temp sensor not allow a cold start?
How do I tell if the evap canister is venting properly? If you remove the gas cap after trying to start it for a while you can hear a gurgling in the tank.
