Cold Starting Problem

[Octillery]

Seems like this cold Canadian winter has been causing some problems with my truck. It seems like after I let it sit for 8+ hours, it takes quite a few tries to start. Seems like it's putting too much gas in; just keeps turning over. But once the engine has fully heated, I can shut it off and it will start perfectly. I don't recall ever having a struggle starting it last winter, so something must have happened between now and then. I have a 1987 VG30I Nissan Hardbody. I recently ran some diagnostics on the ECU and came back with these results: Engine Coolant Temperature Sensor, Ignition Signal, Throttle Valve Switch, ECM, EGR Function, and the Throttle Position Sensor. Now let me give you a brief description of what I have checked already. Back in the spring I replaced my Throttle Position Sensor, but nearing the summer one of the wires in the connector to the TPS came loose. So I had to fix the clip, and reset the TPS. Then about 4 weeks ago, I thought the TPS was the cause of the cold starting, and decided to reset it again, and still am having the same problem. It seems like it has almost gotten worse. Last week I decided to take a look at the Coolant Sensor, I put it in cold water and warmed it up, and measured it with a multimeter, and it worked fine. About three weeks ago, I had a coolant hose have a leak, and thought that possibly because of the low fluid, the Coolant Sensor picked up an error. I'm very puzzled on this situation, and if anyone could lend me a hand, that would be great. I'd be happy to answer any questions anyone has that would possibly lead to a conclusion. Thanks

Well the coolant temp sensor definitely has the ability to cause the ECU to dump too much fuel... although its usually pretty rare that it does it while its cold. How are your ignition components? When was the last time you did a cap/rotor/plugs/wires job?
Try putting the gas pedal to the floor next time it happens, that should let more air in to balance your air/fuel ratio a little better.

Put a head temp sensor in it and probably should have the sub harness to. This sensor is down behind t belt cover area and conector is up at top of t belt covet has to wires in it gray connector been a long time have to think about this one
