HELP!! Car won't start with cold weather!!

[jonysho]

My 91 MTX WILL NOT START in the morning when it is cold outside. I know it's got to be problem with the LPM.

This is what happens... when the temp is usually 40 degrees or lower when I turn on my ignition the fuel pump won't shut off. You know it's just supposed to prime for a second and then kick off, but it keeps running and flood the engine thus nnot starting. But I can pull the LPM out and it will prime perfect and fire right up. Put it back in and no dice, same effect.

What wierd is that it only does this on the first start of the day, after that it start just fine no matter how cold.

I sent the LPM to TED he reprogrammed it but it is still doing it.

My question is has ANYONE ever had this happen to them, and what did they do to fix it?

i read in a post the other day if you floor the gas pedal it cuts off the injectors, so if youre flooding that may be the best thing to do. let it go for a sec then mash the gas.

Considering that the problem is isolated to the LPM which is Ted's I would suggest sending it back to him, have it reprogrammed, and have him test it on a similar SHO it similar weather, this is obviously a bug that is not your problem.

Yeah, even TED said he was baffled by this one. I may end up having to send it back again if he can come up with a solution. until then I guess I just wait. shrug
