SC300 wouldn't rev above 5k sometimes less
So hooked up my Toyobd1 tool and could see it was lean at high rpm so suspected fuel. Tried another maf just in case since thats a 2 min job, but that did nothing. ECU recently reworked by Tanin so knew that wasn't it. TPS showed to be responding on the Toyo tool so figured it was good. Suspected fuel delivery but no easy way to check fuel pressure. If anybody has a suggestion on easy way to check fuel pressure please reply. So, decided to look at the fuel pump. Glad I did, this is what I found.
In case the pic is not clear, screen was shredded and sucked into pump restricting flow. Replaced the screen, luckily I had a spare with all the race car spare parts I have. Problem solved I hope, haven't test drove it yet but seems to run fine. Edit: This is on my red 93 daily driver, think I will do this job proactively on the 92 race car. I took this red one to the track a couple of weeks ago just to play around since the race car has a dead engine and the new one isn't ready. Not much fun to be limited to less than 5000 rpm. Plus this car is still bone stock on suspension and just rolls and rubs the fender wells. But, with this fixed it should be fun on the street again.
