Yes 12.17 volts engine off and fuel pump unplugged 9.61 volts with engine off and fuel pump plugged in. I guess as you said the relay is reducing the amount of volts getting to the pump due to the restriction. Yes I did put a new fuel filter on and don't remember seeing any kinks in the lines...

Ok so I retested with a 14 awg copper wire. Fuel pump backprobed and +B jumped to Fp still reads at 9.61 volts. I unplugged the fuel pump and tested the connector of power supply to fuel pump with +B jumped to Fp and it reads at 12.17 volts. Reconnected the fuel pump and tested the amps of +B...

No haven't tried another cps I've been backprobeing a few things on the ecu I haven't dropped the fuel tank but I did put my inspection camera in the sender unit hole to see the condition of the pump and tank. All looks clean. I just figured something else out hopefully. Jumped +B to Fp on...

Seems like not enough power is getting to the fuel pump. And seems like fpr vsv is not letting vac to the fpr. Also when I shut off the engine fuel pressure dropped to 10 psi fast then held at 10 psi for a good 10 minutes. Am I really facing blockage problems or maybe fuel pump isn't giving...

Ok reran a bunch of test. Fuel pressure +B and Fp 38 psi Idle no fpr 38 psi Idle with fpr 38 psi Snap throttle drops from 38 to 30 psi Full rev drops to 10 psi Volts to fuel pump Idle at 8.78 volts Full rev 11.50 volts Battery 12.6 volts car off 14.5 volts engine running Car idle at 900 rpm...

Will do

Could be true but would think this is a reman starter that I bought three months ago and it started the day I bought it. Wouldn't the company that reman'd it do that? With it having a warranty I think it be better to get an exchange on it. Also still cold here in houston so will probably check...

No it starts every time but it has a loud winning noise like 5 seconds before it starts to spin.

Got the brushes installed a few days ago. It has been cold here in houston so haven't tested anything yet. Now that I got a good iacv on and the idle is perfect now and the charging system should be in good order now i will retest timing, fuel pressure, afm hertz readings, engine codes, and...

got the new brushes in. Will be installing them in later today. Cost me $10 for both.

But luckily the brushes where the same. Figured out swapping the brushes.

I did that and I'm getting the right fuel pressure during the +B and FP jumped, and of course hearing the fuel pump kick on. But I'm reading low fuel pressure at revving. Will do further testing and checking of the fuel system as Pi suggested. Because I have bought a handful of parts I will...

The part number on the alternator I got is 27060-63082 The alternator I already had in the supra has no labels so no part number on that. The one already in the supra is bulkier then the other one I bought. It was the brush as now it is charging since I swapped out the brushes. I will end up...

Ok got the used alternator in yesterday. Didn't fit my supra, bolt holes didn't match. Guy said it was off a 1992 supra turbo and was working before he pulled it off, don't know if there is any difference in the 1992 to 1987. So I just swapped the brushes and installed it and will test it out...

Ordered a used alternator. Hopefully it fixes the charging problem. Then on to fuel problem. Will keep you guys updated.

No not yet as I have been super busy this past two weeks and haven't been able to even look at the supra. Also had issues pop up on my dd i had to spend money on. Will differently get back into it within the next week or two. I know for sure alternator is bad but havent taken it apart yet and im...

Ok got the parts in couple days ago and just got them in the car today. Used fpr vsv, egr vsv, iacv, coil pack harness, and egr modulator. Will try to buy a new alternator brush and see if that fixes my charging problem, if not will just get a new alternator. Then finally back to the fuel issue.

I see a bunch of great fields here. Question is does anyone have access to a 3d printer here? If ya do pm me cause I have a request or more so a part I need made.

Speaking of firearms i also have a dpms ar10, io ak47, and a century arms c93. Word of advice, never buy the century arms c93. Full pos's, never rejects casing properly, double feeds constantly. It was a new gun. I think they screwed up on the recoil spring. Seems tight as hell to me.

Trying living in my shoes. Don't ask me why I do it I just do it. I carry my wallet, phone, three extra mags, my total 8 inch Beretta, my 4 inch blade fixed knife, and my abundance amount of keys on a daily bases. And yes driving with all that is a bit annoying and a pain in my hip. With all...
