93 Isuzu Rodeo LS V6 4x4 auto starting issue.

so truck was running fine when i bought it. I drove it an hour home with
no problems. I was jumping my car and my idiot brother put the jumper cables on wrong terminals:banghead:. the truck was still running untill we turned it off then didnt start back up. So im already guessing battery fried, tested it it was bad so i replaced it. now it will turn over but wont start, found out my #6 ignition coil wasnt geting spark but #1 was, so i replaced ignition coil. now it sound's better but still wont start. i checked all the wires and they all have spark, im checking the plugs in a couple of hours, any ideas??... also was thinking of getting starter fluid for the intake to rule out a fuel problem. thanks an any help will be apreciated.

tested all fuses and thier all good. rechecked everything on ignition side and im getting spark 4 sure, i even tested spark plug wires with ohm meter so their all good. now on the 1st try the truck starts goes up to 1000rpms then stalls right after i start it, but i cant get it to start again:runaround:anyway i got a chilton manual and of course it says nothing about what i should do if the truck doesnt start. waist of $30 bucks, all my relays are good 2. still no ceL codes. can anyone help, truck just wont stay running.:crying::crying::crying::crying::crying::c rying::crying::crying::crying::crying::crying::cry ing::crying::crying::crying::crying: lolol:mad:

chilton manual says 9-13psi for fuel pressure, it starts at 30psi then slowly drops every time the engine rotates. im not sure what could be bad or if this is bad. as thier seems to be more fuel pressure then the book says.

93 isuzu rodeo 3.2 shows 25-30psi at idle with vacuum to regulator, 41-46psi no vacuum and should flow 1/4qt in 15sec
