2351, megasquirt q3 transistor ? no pump prime just on constant ?
Posted by jjcool, Aug-05-06 04:26 AM
hi

i currently have a megsquirt v2.2 its all wired up right as a tripple checked wireing.

my trouble is when the ignition is turned on the fuel pump dont prime and go off after 2-3 seconds?

the fuel pump just come on and dont go off? it just carrys on running?

would q3 transistor cause this to happen on a v2.2 megasquirt?


also noticed in megatune, when i first switch ignition on in bottom left corner, it says the fuel pump is on (connected) and after 2 secs it says the pump is off in megatune ???

again would this lead to a faulty q3 ?



i looked on maplins for the PN2222A transistor however its disscontunued but is the 2N2222A transistor compatable ?
