ME again..have spark now but my injectors arent opening,,,,Lots of fuel presure but wont get f injectors to fire,,,Pls help......What controls the pulse width?????

check red wire at injectors for volts,that wire runs through the whole inj. system if you look at a manual you can trace it out,check fuse link at solenoid i think inj. wiring link is blue.

you cant run a SD ecm for a MAF setup. it wont know how to configure anything. get a new computer

well that makes sense, but 86lx says he runs a 87 ecm in his 93.....sayd works just fine.....not sayin your wrong....i just ran this ecm cause i dont have a MA one yet....have to find one......</P>

his ecm could of been modded:dunno: but if it runs it might not be running correctly. or his computer really is a MAF
