| Hi guys, I recently revived my 90 300zx TT after 5 plus years. I've done the following so far: Drained tanks
New Royal Purple HPS oil with new K&N oil filter
New battery
Cleaned and oiled JWT pop charger Turned over first try but lacking power, topping out at 3k RPM. Then... Replaced fuel pump with Walbro pump
New fuel filter, dampner, regulator and lines
Installed fuel pressure guage Turned over today, same issue, lacking power topping out at 3k rev. When I engage first gear top out at 2k RPM. Fuel pressure idle around 40 psi. I'm not sure where to go from here. Dave N used to tune on my car 10 plus years ago when he was living in MA. At that time he said one of my injectors was on its way out. So is it maybe multiple injector problems I'm having?? I don't want to second guess my fuel pump installation and dive back into the tank. Any help/tests I should perform would be super helpful. I don't have a ton of mechanic experience but plan on making this car my project now that I have time and some money to sink into it.
