problem is on a 1999 formula

ive just recently installed a lq9 bored and stroked to a 427, 232/234 comp cam, stage 3 ported heads, moroso deep sump with perma cool relocation kit.
the problem with my car is that it takes a couple of trys to get it started, then when it starts it usually dies. somethime when i try to give it gas it doesnt even do anything while the car is running then it usually dies out again. also my gauges do some crazy thing when i turn my key into the on position, for example it does what the subaru wrxs do when u start (both the speedo and tach go from 0 shoot up to redline or max point then go right back. also my engine temp and oil pressure gauge do not work, they will sometimes move (but hardly ever).
i also checked all fuses and engine control was blown, i replaced it and same thing, i also rechecked it and its fine.

the car did the same thing before the motor swap but what happened was i pulled my stock ls1 out then put it back in.and it did the same thing, i got it running once but then it ould go back and do the same thing. i also swapped my pcm with a 2000 and then swapped it back i dunno if that would effect anything.

is it a pcm problem or something not connected right?
also the obd2 connector isnt working, (after i pulled the dash, dash is still out)

any help would be great, thanx.

 

well i also have a 99 formy..but havent ran into any of those problems..thank god..i would go and check ALL the wiring and connectors that you can..ALL of them..and hows about a T.U.N.E.? you cant expect that to even contemplate running with out a tune..no way!..and check your sensors too...

 

well i know i need a tune, but i had the same problem before with the stock motor. ive checked the connections and they seem to be in order

 

im going to recheck the oil pressure and ect plugs and wires again, i think thats the problem. i tried reseting the pcm but still no luck.

 

check the 3 grounds on the back of the heads.

 

ya im gunna recheck those as well thanks for the reminder

 

That is exactly where I would start! Check all of your grounds! Then the sensors, MAP, IAC, crank position, etc etc...

 

ok i checked out the grounds and they are good, i replaced the ECT plug now im getting a reading, my oil temp gauge i cant tell if its working incorrectly or not. the car started but if u hold it over 3k rpms it runs fine, anything below it wants to die. also i found out the positive wire for the starter was grounding out on the header, im goin to replace it.

also i took out my a/c stuff but are there vacuum lines i have to block off?

 

ok fix starter problem but discovered my crank position sensor is messed up. the wires pulled out of it. does anyone know which color wires go where on the clip.ror where i can get a wiring diagram for it.

 

Also check your sensor fuse you may have blown it with everything grounding out and the motor will act up cause of that.

 

found a wiring diagram

 

ok cps wired up, car will start with starting fluid and idle fine, in like 5 mins the car will die out. not enough fuel? should i get a base tune on it? im also goin to buy a new oil pressure sending unit.
car is almost there lol.

 

wow this sucks, car seems to be acting worse. i changed the plugs but seems like theres a misfire like crazy. im thinking the pcm is gone.
