My 89 5.7l v8 Camaro iroc-z starts but once I start to go I have to pump the gas for it to barely go and after I manage to make it like 2 or 3 miles I shut it off for like 5 mins then start it back up it will run great up to around a quarter throttle but cuts out if I push the gas more than that and then after around 3 or 4 miles it will start doing the same thing as when I initially started it I have to pump the gas and it will barely move again it idles fine but has a horrible miss once again.. I've never had this problem or heard of anyone else having this problem so please if someone has had this happen please help me out I love my car but very frustrated.....

 

I'll take any advice at this point

 

Fuel filter or fuel pump going south maybe.

 

does sound like a fuel problem. is it carburetor or tbi?

 

Iits had this problem since I got it I just put fuel pump in it now it runs pretty good I tested the injectors and they need replaced most of them read 3.5 ohms and a couple were what they should have been 16 and 17 ohms so 5 need changed so I'll change all of them and it is the 5.7l tpi

 

I also have replaced the distributor and coil just so I knew for sure it wasn't it thanks for the help guys

 

Never seen a fuel pump go kinda half assed like that I thought it was good just by hearing it prime up going to get fuel pressure gauge there is no assuming **** with a car lol most fuel pumps I've had in vehicles either work or don't work
