so, im in the process of buying a 1993 s10 blazer. the guy is telling me that the fuel pump is bad but he says it still runs. just gets real doggie when it warms up. supposedly his mechanic told him the pump is getting warm and not working at full power. now, ive had tons of 1st gen s10's and never heard of this problem. usually when the pump goes, it goes. no half *** working... any thoughts? thanx

 

no body has any ideas on how to hel me here?

 

well a fuel pressure test can tell you if the pumps going or not

96+ Fuel System Diagnosis - Blazer Forum - Chevy Blazer Forums

i found this using the search feature

 

I'd be more likely to suspect the CPI unit, fuel lines under the intake manifold, or fuel pressure regulator, but it's worth taking the time to diagnose it properly. Common issues on the CPI trucks. If you search around you'll find a lot about it

sorry, im new to the forum and still tring to figure out how to use it. where would have been the correct place to post it?

nevermind, i see you put 1st gen tech. thank you for the advise.

ok, i got a dumb question... how do you know if its a TBI or a CPI?
