did you check to see if your fuel lines are getting pinched anywhere while you are taking your gas tank in and out? also change your fuel filter and idk just maybe your oxygen sensors woudl cause the smoke outta the pipes? not sure

hmmm....dizzy module going bad ?
possibly the coil
i didn't quite understand the fuel pressure thing...do you have a guage on it that you can watch when you drive ? it's pretty easy if you don't, just buy one and hook up to the schrader valve w/ a length of braided line, you can zip tie it to the wiper or anything. just to see what it does....5-8 psi fluctuate is ok...it will do that as vac changes from throttle changes. but big fluttering is no good
i think you should isolate whether it is spark or fuel and go from there.
trying to tack both will be harder

RE: problem with red 89 cobra clone (HELP)
today is the same thing.I went out to the car and put the gas pedal to the floor and it started up and reved high, then when the car idle came down it died with gas smoke coming out of the tail pipe. Its got to be gas or electricalbecause the car is getting sparkand starts but then dies. also i bypassed the intra switch and checked therelay under seat and everything is ok and the pump turns on. sometimes it gets fuel in lines and sometime it doesn't, also i tried to start it with starter relay with a screwdriver and it wouldn't start and now my batt gauge says that there is no voltage and when i try to start it it klicks so i ****ed something up i think starter relay.but when this happen my stereo system was bounding and i think the computer is bad because i ran a wire to my starter sil from stearing collumnbecause it wouldn't start without it,so the car would start without clutch in and when i take my battery cables off the car it still has juice from the stereo batts.I have to unplug the fuses so i think whenmy stereo bass was onthe cars volt killed something in elec system dont know going to have to take it in our something what sensor could also be doing this please help help

Just cause it gets some spark doesnt mean you are constantly getting spark. Is the computer poping out any codes? Did you put a fuel presure guage like posted above on it? When was the last time it had a tune up?
