S15 ignition module Sign In

I have a 1988 gmc s15 5 speed 2.5 throttle body injection...ok it started running ruff after startup then one day wouldnt start .. I tuned it up replaced plugs and plugwires, ditributer cap and rotory button. New injecter and fuel filter. Also fuel pump.. Got it back running for couple of weeks then died again....i was told to change the ingnition module but it will start if i pour gas in the throttle body... Could it still be the ignition module that i did not change?.... Thanks

You need to use a fuel pressure gauges and test the fuel pressure and if you don't have the correct pressure, then troubleshoot why not.

Its been sitting for a while now also .. The gas doesnt smell strong at all... More of an oily smell

Common sense tells you stale gas isn't going to run. Could have sa bad pump also. You still need to test the fuel pressure.
