Oldsmobile Aurora Fuel pressure Problem
I'm working on a olds aurora with a 3.5 engine and I get a code PO301. And I've changed coil packs 02sensors, changed spark plugs and the boots for the spark plugs my customer said it ran fine when he brought it to me to tune it up and now I've been working on it ever since then and also I checked the compression it is fine too

there is no codes 301 but a 300 for a 3.5 but check your fuel pressure first that will causee misfires. if the customer brought it in for a misfire then it could have been the fulep pump all along or a vacuum leak. fuel pressure shold be 41-47 psi if lower tehn replace the pump
