Have you checked the fuel pressure and for trouble codes?

Todd Hubler

how do I check fuel pressure? What are trouble codes? I'm a rookie at this. Please help.


Ok then I would suggest that you check out You Tube, there is all kinds of videos on how to pull the codes from your obd1 GM product and how to get fuel pressure readings, but you will need a fuel pressure testing set of tools fittings and gauges, harbor freight did have them at one time. HTH
