My sr is completely rebuilt
Stock ecu and smic CA pistons, manely rods, acl bearings, crank polished,(crank, piston and rod balanced together), bc spring and retainer, shims checked installed correctly, everything torqued correctly, apexi head gasket, arp head studs, reinstalled t25 that hasn't been ran for over 4 years One ecu didn't allow 3 of the plugs to spark so I switched to another and motor started right up, but not smooth Cams and crank aligned and timed right with cas The motor smokes white the whole time I Rev the motor and I'm not hearing the spooling or blow off(smic) The plugs are black right away...running rich? It backs fire when I Rev also I'll try to upload a video |

Was also thinking possibly my turbo is bad?
I have another t25 and t28 Just don't want to struggle in replacing it as I've been waiting 3 years for this |

Leaky Injector
|
I had this issue when driving in extremely wet conditions. It was so bad one time I had a tow to a shop and they said they'd check it out the next day. When they got to it; it ran fine no issues . I chalked it up to a wet MAF. But I would imagine whatever happened to it (the MAF) could happen wet or dry.

What slidins13 said. Your engine should run horribly on the verge of stalling or even stall when your MAF is unplugged. Check your wiring of the MAF too and make sure all that's good.

if the smoke is thick white it's burning coolant (most likely head gasket keep an eye on coolant overflow level) if its blueish or grey it's probably burning oil so keep checking oil level

I went to check on it
I had opened the valve cover lid and could smell gas When I first tried to start the car with the bad ecu I'm sure I flooded the cylinders and since the rings are seated fuel worked it's way into the oil? I will pick up some oil and replace it tmrw |

Pull codes from your ecu, replace your oil and filter. Before you turn the ignition on, check the injectors for leaks. You want your bov to make noise while your engine runs like shit, prioritize! Your cluster probably doesnt work because of the dash connector? Pick a problem stick with it until it's fixed. Also do some reading, you might learn how to troubleshoot that way.

Thank you for the grammar tip! I'll be sure to take your advice when I'm writing and essay for you.
I don't understand you statement about wanting my bov to make noise while my engine runs like shit. The dash plug to the ecu is connected correctly with the 6 corresponding wires I've been searching on Google everyday for each problem It's never stated how they fixed their problem I'm going to double check the trans harness to fuse box and the temp senors plugged in correctly |

did the gauges work at any point before the built motor went in? or was the car never running until this motor?
also have you made sure the coolant level hasnt gone down? |

Well rpms don't work on SOHC with sr, but I would disconnect the clip you had to solder the wires for and test the pinout for power and test the wires going to the temp sensor. Either that or try putting in a new temp sensor if you haven't already..
