Stumbling Start-Up (Page 2/2) labbe001 MAR 01, 10:17 AM quote Originally posted by TM_Fiero: I had a very similar problem. I eventually found out the engine was flooding itself when starting. Ran normal once started and warmed up. Turned out to be the cold start injector system not working properly. Unplugged the temp sensor for the cold start system. Now starts without any problems. Would be an easy thing to check, just pull one plug and give it a try. Yes I'll definitely give that a try. Thank you. Unfortunately, I have to pull the fuel tank anyway to fix the sending unit. I have a short on the circuit so there's either bad wiring or a bad unit. Since I'm pulling the tank anyway, I'm going to verify all is well with the pump. The PO said he installed a high volume Delphi Fuel Pump (FE0114) so something must have gotten crossed/shorted during that process. labbe001 MAR 01, 06:25 PM So question. I pulled the tank and the sending unit. I did a continuity test on the power (purple) and ground (black) wires and sure enough, I get a beeping notification from my multimeter signifying a closed circuit. Should this be happening? I’m assuming there is a grounding issue some where. Since the sending unit is just a resistor 0-90 ohms, I checked resistance by hooking up my multimeter and lifting the float arm. Everything seems to be. The display showed the resistor functioning as it should. So I’m confused. Should there be continuity (or a closed circuit) between the hot (purple) and ground (black) on the sending unit harness?
