i completed my swap today everything worked good took it for a ride brought it back and left it parked for awhile so we decide to extend the MAF wires since it was the last thing we cut it off wire it on some new wire color to color and now the car wont start we tried removing the maf plug checked fuel pressure, spark, injectors thats all good it just wont fire up is the harness fried? thats what im beginning to think i need some help it really sucks thinking everything is good was gonna drive it home tonight and now its gonna sit again for who knows how long

double check the wires to maf, check all grounds, and check your starter even though unlikely.

i checked the grounds took off the wires i used to wire up the maf and wired that back up it sounds like it wants to start like it will fire for a second then give up im gonna see if i can get a ecu tomorrow and try it out i think the ecu may be messed up it ran great before this maf issue thing

did you clean out the maf or anything? Cuz if you broke the little sensors in the maf it will throw off air fuel enough to run like poop.

so i found out i have no injector pulse when i crank it to start it but when i put starting fluid in it will start and have injector pulse but its really rough so does this mean the cam sensor or crank sensor may be bad? and is there any way to check the sensors?
