I was installing 650 cc injectors on my 97 gsx. I have an upgraded and rewired fuel pump and an safc along with a logger. I finished the injector install and went to double check all my connections up front and at the pump. I plugged the pump back in and accidently touched 2 terminals together on the relay. Well the fuse popped so I replaced it. I started up the car and took it for a drive. I did a little tuning and had it tuned in at 19 psi .... it was reading .94v all the way across in 3rd and 17 degrees timing advance. I drove it around for 30 minutes or so and then took it home since it was getting late. Today I got up and started up the car and let it warm up. As soon as I pulled out of my driveway and laid on the gas the car started jerking really hard and really fast. Like I was hitting fuel cut 100000 times a second. It was also pulling timing like crazy. If I don't hit boost and slowly touch the gas its semi driveable but as soon as I touch the pedal it goes crazy. I can't figure out what it is. I switchd the injectors back to stock and put my old settings back in the safc but it didnt do anything .... I changed the spark plugs back to some POS bosch plugs .... still didn't fix it. I reset the ecu ... didn't fix it. Anyone have any sorta idea? I know 19 psi wasn't too much ... I ran it at 20 for a while and it was fine .... Please help!!!! Do I just need a new relay for the pump or would the car not run at all then? Maybe a wire for the safc came undone? Thanks.
