help with haywire initial sequence
dang

I've got a mosfet (RFP12N10L) array to control five solenoids. Currently I am testing it with LEDs to get bugs worked out prior to final hookup.
Problem is: with a repetative sequence of pulses (either a do, loop or a goto statement) the first time through after power-on is haywire; multiple LEDs lighting simultaneously, making blinky half pulses, etc. Then, after initial sequence is through and starts again on the first repeat she runs normally, sequencing as the program indicates. The haywire period is the same with each power-on. This happens in roughly the same manner with multiple test programs using all the ways I know of programming blinking sequences that repeat.
Could this be a wiring problem? All connections are decent and wriggling wires makes no difference.
I'm stumped.
