91 Ranger spark issue
Got a 91 ranger 2.3 the primary coil isnt getting triggered by the ecu. its not the ecu,the coil has power going to it. I tried another coil,ecu,maf,iginition module,you name it..the truck will start on the secondary coil if you crank it long enough..when it does run the tach is way off..It did this before and it had a crank sensor code so i replaced that as well as the timing belt,plugs,wires,etc..still doing the same without the crank sensor code....any ideas?
foot note i put in a 91 mustang ecu which is only a four plug computer and I started it,firing the primary plugs instead of the secondary. so i have therefore verified the wiring to that primary coilpack is all fine and working..I used to be a ford tech in a dealer so I know enough about eec IV to know to try that,yet something stupid has stumped me haha
