The car in question is a 1990 talon tsi awd, not the car in my profile. The only mod done to it is a Dejon intake pipe with bov recirculated and 1g unhacked maf. The problem is that the vehicle will start with started fluid, run rough for about a few minutes then, dies slowly.
Quick stats:
Compression read 165 across the board
Have spark all four: new wires, new distributor, new ngk plugs gapped to .28
Have fuel coming out of hp fuel hose while cranking and new fuel filter.
I have Double checked the cas for 180* flip around.
My timing marks all line up every 6 turns with 1/2 ratchet.
None of my gauges work: tach, oil pressure, gas, etc
Dash lights DO work though including turn signals, high beam, door open etc.
No CEL or Other dummy lights while starting.
Have checked to see if ecu but another 90 ecu out of running car didnt fix anything.
Alt fuse replaced with brand new fuse, checked mpi fuses, and fuel pump fuse.
Have done a boost leak and fixed major leak from stock ic piping.
Holds 15 psi fine for 30 seconds during boost leak test.
Has about 3 gallons of fresh fuel 93 oct. drained out old fluid and cleaned gas tank.
Also replaced the fuel pump with good stock unit and restudded cap. no leaks

Any suggestions on continuing my trouble shooting of this car?
I learned everything above ^^^ using older posts but could not trace cause.
