low idle and no acceleration

[Zamoraloza]

So I just replaced all 6 fuel injectors, fuel filter, fuel pressure regulator, MAF sensor, and ignition coil on my '85 Celica Supra. I put everything back together all excited that it will run once again. but when I go to turn it on it sounds real nasty and only idles at 600 and when I press on the gas there is no acceleration. this problem is driving me mad I have checked that the crank pulley, cam pulley's and the cam housing and the cam line up when you take off the oil cap. PLEASEE HELP MEEE!!!

Check timing?

[supraguy1230]

check to make sure u plugged everything back in, i had something similar happen, and it was a duh moment when i found that the 1 injector plug came out after i had put the pelum back on.

fuel pump?

My car had the same symptoms as it was sitting in a barn for 3 years before I started to drive it. It idled at 700rpm and poor sluggish acceleration

It gradually started to pick up revs and acceleration over the next 500 miles I put it down to bad fuel in the tank I don't no if your car was of the road or not but thats whot happened me now it's idling at 900rpm and accelerating smoothly

Clogged Fuel socket filter intank?

I had this problem, my gaz tank was rusted from the interior and rust was the restrictor in the intank filter.

To know if it's the problem, you have to monitor your fuel pressure and it should be always around 40 PSI or more, never below 35 PSI

MAF Sensor? Do you have a stand-alone ECU that uses one? Stock 85 comes with an AFM. It you did replace AFM, it needs to be specific to a 83-85 Supra. Did it run OK before the work you did?
