i recently installed focus fuel pumps, and ever since then the car is running like crap. something went wrong, has anyone did this before, i think i mest up the wiring but on the other hand how could i, that look so simple, my fuel pressure is 75 psi, is that normal with the focus pumps? and when the car is off and i turn the ignitios key on the fuel pumps work all the time they never go off like they should in any other car after a couple seconds, and also i have a trouble code p1237- fuel pump secondary circuit(fuel pump driver module) i even switch the fpdm and no difference, is theres anything else that i might do .
