The distributor shaft should not move from side to side. The tps has to be adjusted with a voltage meter to the correct settings. Plugs, wires, dist cap and rotor should be changed at the same time and this will eliminate any carbon tracking from wire to plug resulting in a misfire.

Change your fuel filter. Replace the distributor cap and rotor. If you have the HEI ignition, they are really bad about burning through the igniton rotor.

If you pull a breather hose loose and spray some carb cleaner down the throat and replace the hose will it try to start? You may have burnt the ignition fuse while tring to start it before. Check all fuses including under the hood. Check them all but we are looking mainly for the one marked ignition. If no luck there then I want you to test the ignition modulator. it is the little black or grey plastic coated half moon shaped box under the distributor cap mounted on the top of the distributor wrapped half way around the middle shaft. In order to check this you will need to take a hair dryer and heat the modulator up to very warm but be sure not to melt the outer covering. Hurry and replace the distrib. cap and get the dryer out of the way of the fan. try to start it. If it sputters or maybe even starts it is the culprit. I have had them even start and keep running after the test but will not start again after you shut it down. Let me know if we have gotten any place so far and I will go from there. Raz

87 gmc sub runs for a while then dies

I had a 99 Suburban that did almost the same thing, it turned out to be the Catyletic Converters were plugged. Try taking the exhaust pipe loose at the manifold for test purposes. If it runs good with the pipes loose, that's the problem. Replace the Cat's. There were no codes for either, it would start and run nice for about 5 seconds, then run rough and then stall.

GM TBI low voltage at the injectors

sounds like a computer issue on the burb, but i would check the IAC(idle air control) valve and the TPS(throttle position sensor) first.
I would start with the IAC on the 93'.

It may sound obvious, but have you changed your inline fuel filter? if so, try a"fuel system cleaning" next.  available at most oil change garages. It runs anywhere between $60-120 and does a pretty thorough job of flushing out the fuel injectors and cleaning out of all the fuel delivery components. I've seen some amazing results with the flush.

88 Suburban too much fuel to start

which wires, to the injectors ? You don't wanna disconnect the Idle air control or the TPS...while cranking, the TPS if improperly installed can be an issue, but the IAC if stuck closed, wont let the car idle, neither will the EGR if it is hung open. also diconnect the map sensor, if it improves, replace it
