[urq] below 35 degrees cold start problem

[urq]

Did you re-do the wiring to the ECU when you did the conversion?  IME the
MAC-02 is intolerant of low supply voltage ...  Perhaps you can get one of
those portable jump start boxes and keep it inside, then when you go to
start your car you can have a little bit of a boost.  

You may be right about the slow crank rate though too ... I had a problem on
my V8 where the starter was getting weak and the ECU wasn't getting a good
enough signal to fire the engine.  A replacement starter made the motor
crank faster and start almost immediately.  Perhaps you can try thinner oil?

My '85 WX-powered 4k will not fire when the temp drops below around 35
degree.  The starter turns, but I don't get the fuel pump or spark.  I'm
thinking that the battery is loosing amperage as the temp falls causing the
starter to turn slower and therefor the ECU can't "see" the engine turning
over?

BTW, the battery has been relocated to the trunk and is connected to the
engine via a 1 gauge cable.  Should I try a stronger battery or a thicker
cable?  I can jump it with my P'stroke F250 (two batteries) and she'll
fire....but that doesn't help me when I'm away from the house! 

Anybody got a better idea?

Thanks,
