You don;t need a code reader to check fuel pressure look at the sticky { how to check regulated fuel pressure } at the top of the second gen section and follow it step by step
|
Yeah, you can rent (for free) a fuel pressure tester at pretty much any parts store. Super easy to check. Can save you wasting money replacing the wrong part

Thank you for your help.

Okay, yes the cat has been replaced with a straight pipe.
Took it to AutoZone. It threw 5 codes 2 0300 0171. And 2 0101. The code reader says the blazer needs a fuel regulator. Which makes sense because half of air filter is missing. Me and buddy are now tear apart the carb(injectors) to replace this part. Hope this fixes it. All above can be caused by a bad cat low fuel pressure and such. There is no code for a fuel regulator as the computer does not monitor fuel pressures - Fix the air cleaner, clean the maf with cleaner made for it and do the fuel pressure tests 100% as sticky tells you too before you replace anything and spend money you don't need too spend .... The failed cat was a easy guess now it's time to test and trouble shoot while you keep cash in wallet and wallet in hip pocket ...... |
Thank you for your help.
